1.1 INTRODUCTION
The 2570EA MPC is a stand-alone, 2-1/8 inch (outer diameter) cased-hole electronics
instrument designed to operate under the 3504 telemetry protocol. This protocol has
undergone extensive improvements for multi- and single-conductor communications.
These new telemetry improvements require both software and hardware modifications. The
EA is designed to run with either option of two MA sections, the 2570MA (2-1/8 inch OD)

The primary purpose of this new service is to provide for the customer a non-ballistic,
non-chemical alternative to parting downhole tubulars. The MPC has a built-in casing
collar locator, and x-z accelerometers for positional and vibrational assistance, respectively.
The weight of the 2570 EA/MA Mechanical Pipe Cutter instrument is 141 pounds and it is
17.75 ft long using the 50 mm bullnose blade combination, for the 2571MA option it is 183

pounds and 17.875 ft long. The maximum cutting wall thickness varies based with
blade and MA selection and should not exceed 0.5 inch for 50mm blade or 0.6875 inch
for the 2-1/8 inch OD tool size when using a 60 mm blade. For the 2571MA (the 3¼
inch OD tool), which uses a 63 mm blade, the maximum wall thickness should not exceed
0.75 inch.
The Mechanical Pipe Cutter (MPC) Instrument, Series 2570/1, has two sections: 2570EA
(F131144000) and 2570MA (F131143000) with an O.D. of 2-1/8 in. or a 2571MA
(F130091000) with an O.D. of 3¼ inch, targeted to the cased-hole market for pipe recovery
Use for Reference Only

and in some special situations can be applied to free drillpipe cutting. Also, under special
conditions and with proper planning, retrieval and cutting of packer elements and/or
patches can be achieved.
The tool has a rotating cutting head with retractable anchor arms that will cut the pipe,
tubing, or casing without the use of explosives or dangerous chemicals. Chemical and jet
cutters have environmental limitations and require large logistical efforts, e.g., military
escorts, flight transportation permissions, waste disposal or licensing. This tool addresses
the very high demanding environments, where jet and chemical cutter technologies cannot
be used or are difficult to use.

1.2 MPC SERVICE DESCRIPTION

The main application of the pipe cutter tool is to cut production tubing, liners, casings and
drillpipe. Special applications are required to cut premier packers and flexible pack-off
tubing hangers. For example, MPC is capable of cutting any of the following (see Table 1):

1.3 MPC OPERATING SPECIFICATIONS AND LIMITS

The MPC instrument is a 3504 protocol tool; it is not combinable with other logging
instruments. The logging speed used should be based on what is necessary to obtain good
collars either while running in or pulling out of the well. An adequate speed is in the range
of 25–35 ft/min, and it is recommended to tie-in when logging up.
The standard string configuration is to run the MPC EA and MA sections. If necessary,
sinker bars may be incorporated into the logging string just above the A3 cable head
Use for Reference Only

connection. It runs decentralized to maximize the borehole signal of the CCL. A built-in
accelerometer section is used to help determine tool motion during the cutting process and
to help define the final moment of tubular separations. The tool is designed to operate at a
temperature of 392 °F (200 °C) for 1 hour at a maximum pressure of 20,000 psi.

Table 2 – MPC Operating Specifications and Limits

Specification Limit
Operational Temperature Range (min/max): 200 °C for one hour
Maximum Hydrostatic Pressure: 20,000 psi
Operating Medium: Oil, Gas, Brine, Mud, CaCl, CaBr or ZnBr
Cutting Time: < 30 minutes
Maximum Operating Depth: To be determined
Power Required for Operation 1500 Watts

When using the MPC, it MUST be run with a 4503XB or the 4505XA RAP surface panel,
due to additional power requirements and adjustments made to the communication systems
hardware and software. The use of an additional 2010 DC power supply is generally
required.
This service cannot be run on a 4501XA/XB panel with a 3765 Line Control Panel. This is
due to the maximum voltage limitation of the 3765 LCP (@ 600 VDC). This limit is lower
than what may be required to achieve the proper cable head voltage during some cutting
operations. To maintain the required 600 VDC at the cable head, as much as 700 - 750
VDC have been observed at the surface panel. This will be based upon line lengths and
pipe conditions, along with tool loads and actual cutting requirements. Additionally, there
are many sources of communication interference because these panels do not have the
necessary chokes and filters to control our signals while cutting. Using improper
combinations of LCP and Acquisition panels could result in T/O and NVM errors, which
ultimately can cause loss of control of the tool.
Avoid powering up the MPC instrument at surface when possible. Proper safety monitoring
of personnel and equipment should be used whenever the instrument is powered up on the
surface.
Use Appendix A and Appendix C as guides for choosing which blade and which
extensions are needed to best perform a 2570MA job.

When using the MPC it MUST be run with a 4503XB with 5756XC, XD (both with limitations)
or 5771XA or the 4505XA RAP, due to additional power requirements and adjustments made to
the communication systems hardware and software. The use of a 2010 DC power supply is also
required.
If using a 4503XB, additional noise will be seen on system during
cutting operations, unless used with the 5771XA LCP. Use with the
5756 may result in communications loss and unsuccessful operations.
Note It is not recommended to run the tool using the 4503 panel, unless
used in combination with the 5771XA, but if necessary, you can use
different combinations, with extreme caution and if you have prior user
knowledge. Do not run combinations that may lose communications
without first notifying the customer.

This service cannot be run on a 4501XA/XB panel with a 3765 Line Control Panel. This is due to
the maximum voltage limitation of the 3765 LCP (which is 600 VDC). This limit is lower than
what may be required to achieve the proper cable head voltage during some cutting operations. To
maintain the required 600 VDC at the cable head as much as 700-750 VDC have been observed
on the 2010 power supply. This, of course, will be based upon line lengths and pipe conditions,
along with tool loads and actual cutting requirements. Additionally, there are many sources of
communication interference because these panels do not have the necessary chokes and filters to
control our signals while cutting.
Avoid powering up the MPC instrument at surface when possible. Proper safety monitoring of
personnel and equipment should be used whenever the instrument is powered up on the surface.

It is recommended to use a 20,000-ft multi-conductor wireline or 5707 15,000-ft wireline
simulator as the wireline, since these two options are generally available in most locations. With
the tool out of the housing and on a proper non-conductive surface, connect the wireline
(conductor 7) to the booted connector coming out of the uphole end of the chassis. Connect the
alligator clip to the chassis. Make sure the clip connects to non-anodized metal to make a good
electrical contact.

signal on pin 22.

3. Connect the oscilloscope and set it up.
4. Connect the scope channel 1 to TP15 clip lead and channel 2 to the clip lead on pin 7
of U22.
5. Ground the scope probes to TP22 and 25 (no clip lead extension). Be careful not to
pull hard on these or you’ll pull them off the board.
6. Connect the scope earth ground connection to the chassis of the 2570EA with a clip

lead. Make sure the chassis point you clip to is not anodized.
7. Set the scope so both traces are at 500mV/div and DC coupling and 20 MHz BW
limiting.
8. Set the time base at 100 uS/div.
9. Trigger on the channel 2 and at ~200mV (noise reject mode). Set the trigger holdoff
to 100mS.
10. Adjust the 0V line of channel 2 so it is on top of the baseline of the signal on
channel 1. This will allow you to compare the peak-to-peak amplitudes of the two
signals. See Figure 11 below.

Figure 11 – Overlay of Two Signals Ch1 & Ch2 as Seen on Remote Oscilloscope Connected to Tool

11. In the transmitter/Receiver ECLIPS window, use the slide bar to adjust the TX gain
until the amplitude on the Channel 2 is 500mV p–p on the oscilloscope.
12. Adjust the R134 pot so the channel 1 signal is ~ 2Vp-p.
13. Adjust the pot in the direction that reduces amplitude of the channel 1 signal. It
should be smoothly reduced to a level of 400mV peak - peak. If it rapidly jumps to a
high or low value while decreasing down to 400mVp-p, the pot is damaged. Turn in
the tool for repairs to replace the pot.
14. Reverse the rotation of the pot screw to increase the gain smoothly until the channel 1
signal amplitude reaches 9.5V p-p. The gain should smoothly increase in value with
no sudden changes in signal amplitude. If there is a sudden change in the gain as the
screw is turned, the pot needs replacement.
15. If the pot goes from minimum gain to maximum gain in a smooth manner, the pot has
passed the test and can be adjusted for the best communications.

At this point, place the settings for TX and RX at the surface system both to zero and
adjust the pot until the tool responds with the acquisition system and line conditions. Once
this setting has been found, you can place a bit of RTV on the pot and use this adjusted
value for your tool setting (place a note in the tool history folder of how many turns you
used for specific line and length). If you have additional concerns follow the process

Use for Reference Only

Set up the telemetry receiver circuit by following the steps below:

1. Go to the Transmitter/Receiver window in ECLIPS and adjust the TX gain to “-6”.
2. Move the short micro-grabber clip lead from U22 and connect it to TP24 on the Com
Controller digital board (A3002155000).
3. Set both traces at 500mV/div.
4. Set the 0V level of both traces on the second voltage division line from the bottom of
the scope screen.
5. Set the time base at 100uS/div.

it toggles between two DC values when the blue trace crosses it. Verify the
comparison values are 1.45V ± 0.05V and 1.9V ± 0.05V.
8. Turn R134 to adjust the amplitude of the channel 1 until the peak to peak amplitude
is approximately 1V as shown in Figure 12 below. This should be in the middle of
the tunable range.

11. The LED DS06 on the com controller (A3002155000) should start blinking every
time the tool transmits. You should be able to hear an audible change as
communications are established.
12. Go back to the Transmitters/Receivers window. Adjust the RX gain until the
amplitude of the tool response seen on the oscilloscope is ~5V peak to peak as seen
on the surface system oscilloscope.

13. Make sure the 3504 2570EA is selected in the Rx/Tx window (this should be the only
option). TRAIN the tool by pressing the Start button (note: you must have a response
from the tool for a proper train to occur). If there is a train error, a message will
appear in the SYSLOG window. If train goes well, there will be no negative message,
but the surface panel will now be tuned for the response received from the tool. The
actual GAP and Threshold values can be written down in the tool notes and saved in
the tool history folder by looking at the SYSLOG message for the proper system
values. Save these values for future use and record the line type and length for
additional reference in both places.
14. Now go back to the acquisition system and check the telemetry status by clicking the
WTS menu in the ECLIPS Data Acquisition Window and selecting Telemetry Status.

16. Once the downhole or tool pots have been established, the next step is to find the
optimal setting of the TX gain range that the tool responds to. Reduce the TX gain
until the tool stops talking, then increase the TX range until the tool starts talking. Go
up high enough to lose the signal again (when the tool stops talking). This provides
you with the user range; record these values for future reference and knowledge. Set
the optimal TX gain value to the value 1/3 from the bottom between these two
operating Min/ Max gain values.

TOOL Re-Init downloads the system settings to the tool after communications have been
established. Currently this only downloads the CCL GAIN to the tool. A separate RESET
option is available to re-initialize the tool motors.
5.2.1 CCL Gain
Use the MPC: CCL Gain Index to increase the gain of the CCL to an appropriate level
while logging to obtain a proper CCL Signal. The signal can be gained up to 7 times. From
the Data Acquisition Main Menu, Select Tool, then MPC: CCL Gain. The default value is
4 as the system starts; however, if the tool is not in proper communication, the default is
never seen by the tool, so it may be necessary to resend the command, once
communications have been established. Also, you can send the tool re-init command, as
this will also accomplish the reload of the default CCL value.

On the job use of this window is not recommended. The MOTOR ON button will turn on
the Hydraulic Motor, which prepares the hydraulics for activation purposes. This is the
Motor that starts circulating or cycling the hydraulic oil. The MOTOR OFF button will turn
off (or potentially halt) the hydraulic motor operation. SOLENOID ON will activate or

5.2.3 MPC: Main/Feed Motor
On-the-job use of this window is not recommended. This tool command section is
primarily used for testing, assembly and disassembly purposes only. See the Maintenance
Manual and the listing below.
5.2.3.1 Summary of Main/Feed Motor Commands
• Advance Milling Disk Feed
• Retract Milling Disk Feed
• Freeze Feed Motor
• Start Forward Main Motor Rotation
• Start Backward Main Motor Rotation
• Stop Main Motor Rotation
• Start Cutting Process
• Stop Cutting Process
• Update Cutting Parameters Table
• End FPRC Value (=PODX)
From the MPC Control window you can perform the standard command sequence.
However, from the Main and Feed Motor sections of the tool, a user-selected order may be
obtained. The MPC Control is the primary window in which most typical MPC motor
operations will occur. However, by using the MPC Main/Feed Motor window the user can
override the typical tool motor operations, as such the typical user will not need to use this
window except during lab testing and only for surface check out and post job testing
purposes.
5.2.3.2 Milling Disk Feed
The ADVANCE allows the user to advance the mill feed motor, which controls the arm
section from the home position to the full arm extension or the FPRC; this can be observed
to go from 0 to 320. The FREEZE will halt, suspend or stop the arm at its current position
in the operating cycle. The RETRACT button will return the arm to the “at rest” or home
position.

or rotation is 4000 RPM; however, only in the forward rotation mode can the speed be
changed or controlled via the speed selection made off the MPC Main Tool control window.
The STOP ROTATION will freeze or halt any rotation of the blade and head
simultaneously. The START BACKWARD will allow a reversal or clockwise rotational
test of the blade only at 4000 RPM. This option should only be used during the job if the
blade is somehow stuck in position during a cut and cannot be returned back to the home
position.
The Main Motor and Milling Disk Feed motor can both be controlled by using the
Use for Reference Only

following buttons. It is important to note that any combination of these commands can be
sent and used at any time and that this window will override any currently sent command
(via the MPC Control). Therefore, it is vital not to have this window active during the
actual cutting process on the job.
Tool damage is possible if the Main Motor window is
kept open during the cutting process.
• This window is for lab check-out and testing
purposes only.
NOTICE • Blade damage or possible tool damage can result
from improper use of these tool controls; only
experienced users should attempt to use these
controls.

5.2.4 MPC: Firmware Versions

Use for Reference Only

Use this selection to upload and check on the status of your tool’s embedded firmware
versions for the Communication DSP board, the Communications FPGA, the Main Feed
DSP, and the Hydraulic DSP version. If necessary, request an update from your lab
supervisor if these are not up to date with the latest suggested versions (as of January 2012,
all versions should be 130 or later, with the exception of the COMM FPGA remaining
at 100).
5.2.4.1 Latest Firmware Levels are 130/100/130/130 or Later
• MPC Versions: COMM DSP: 130, COMM FPGA: 100
• MPC Versions: MAIN-FEED DSP: 130, HYDRAULIC DSP: 130
5.2.4.2 Main-Feed DSP 130 Firmware Operational Sequence
1. This sequence backs up the tool to set the stop location. Stop is defined as when Feed
current exceeds a threshold (~80mA). The FPRC is reset to “0”.
2. Main motor is ramped up to the targeted RPM, as set by the engineer in MPC Control.
3. The tool goes into what is called the CUTBRASS mode: here the brass insert will be
cut, if installed.
4. When the blade (FPRC) gets to tool OD, halt the Feed motor and calibrate the main
motor current. This is used to calculate the “ID detect” logic. This takes about
5 seconds.
5. Restart the Feed motor and you are now in the FIND ID state, FRATE set to 200.
This is done by checking the Main motor current against the DETECT ID threshold.
6. The tool finds the ID, so retract the head a little bit; then find it again, this time at a
slower FRATE of 50.
7. Find the ID a second time, retract a little bit again and set the feed rate to the cutting
rate selected by the engineer.
8. Start actual cutting of pipe now.
9. If the main motor voltage <425V or main motor RPM <2000, then the blade is stuck,
so retract a very small amount (a “soft reset”).
10. Wait until voltage >475 and RPM >2500; then go back to the cutting state.

11. Cutting is stopped when you reach pipe PODx (pipe overcut value), or maximum
cutting size, or the engineer stops the cut or the tool receives a fault (e.g., the current
is too high, the voltage is too low, etc.). This is called a “hard reset.”
5.2.4.3 Internal Hardware Reset (Hard Reset)
Document is Out of Date - Currently under Review

There are hardware limits that will set the main motor fault light in the ECLIPS MPC
Control window.
If the cable head voltage dips below 300V or the motor phase current exceeds 5A (peak),
the motor will immediately stop and the feed motor will retract. The main motor fault light
will turn on.
Note that this 5A peak current is inside the tool via a 600W control system; it is never seen
on the wireline. The most you should expect to see on the wireline with respect to current
should be not more than about 1.5A. The main driver is a power in = power out device. So
Use for Reference Only

when the input is 600V @ 1A, the output could be 100V at 6A or 300V at 2A, depending
upon the specific needs of the tool. 600W in = 600W out, at a different voltage and current
level.
In this type of scenario, the fault generally happens so fast that the firmware cannot detect
it. These are set by hardware comparators that are in direct control of inhibiting the drive
signals. It is also important to note that this hardware fault only affects the main motor and
does not affect the hydraulic arms, which (if deployed) remain anchored.
A new start cut command will clear the fault light and attempt a new cut. If the problem is
still there, the fault light will reappear.

• Cutting Progress: controls START and STOP
• Cutting Progress, Status Display: presents disk diameter estimated value based on
user-defined units. The % status display represents the cut amount as calculated from
the initial detected wall contact to the user-entered Pipe OD value.

Figure 24 below shows a typical depiction of the status of the MPC tool after the anchor
arms have been set and when the cutting “Start Cut” button is active, which allows the
START cut use. The surface software is designed to control the cutting process in that it
prevents someone from accidentally starting the cutting process if the anchor arms are not
set first. The interface allows the user to select the Conductor type which will default
automatically to a single-conductor line, but if the user makes any changes, this new value

will be saved to the working directory. If the user changes the working directory, the
wireline select will once again default to single-conductor line until the user changes it.
The pipe selected here was entered as 5.5 inches, but the values will default to the

once proper communications have been established for any of these controls. The user
has selected to cut an additional 0.25 inch past the pipe OD, by entering in a value of
5.75 inches. A default feed rate of 1.0 mm/min will normally be displayed and the
tool’s “actual” value will show in the active window below the engineer-selected
cutting feed rate.
The RPM default is 6000 RPM and the blade size will default to the smaller blade size
if an option is available; here the only option is the 63-mm or 2.48-inch blade. It is
important for the user to be aware that any single change made via the MPC control

window will automatically force a download of all control parameters to the tool every
time a change is made.

5.3.2 Pre-Operational Sequence and Lab Cuts

1. After setting up communications with the tool and the surface acquisition system, set
CHV to 500 V and train on the tool signal.
2. Place the tool on a rack or somewhere safe in the yard or lab; be sure to place the
blade at the designated cut position within the test pipe. Use of an umbilical between
Document is Out of Date - Currently under Review

the EA and MA section may be preferable. Typically, in lab conditions the cut is done
in a near-horizontal position, with a water supply trickling through to remove debris
and keep the blade clean. However, it may be necessary to make variations to this
based on your local conditions and equipment availability. Be sure to coat the blade
prior to this step with TUNCUT grease!
3. Start a time-driven file acquisition, and record every time — even lab cuts, demos,
surface checks and tests. This is beneficial for post-review of results and to provide
proof to customers and our technical personnel of all operational events.
Use for Reference Only

4. Anchor the MPC inside the tubing/pipe by sending the “Deploy Arms” command via
the MPC Control Window. Note that the 2010 current draw should be around ~0.20A
initially, then it will settle back to within the range of ~0.12 to 0.18A. The hydraulic
motor RPM should stabilize around 850 to 1400 RPM (~1080 RPM, ideally) when
the arms are fully locked. This may take several minutes, so be patient. If there is too
long of a delay upon deployment, this indicates the tool needs to go to the lab for a
hydraulic oil change and checkout. The hydraulic status display will change to reflect
this new “Locked Arms” condition once the arms are fully extended. All associated
curves should be smooth and stable in appearance.
5. Set Main Motor RPM (6000), validate Diameter Disk Size (50mm), Feed Rate
(1 mm/min), and POD (2.625 in) and PODX (3 in) via the MPC Control window.
Selection of the POD, PODX, blade size and main motor RPM will depend on your
test pipe selection and material conditions. Removal of the bullnose is common for
DEMO purposes and lab tests, extreme care should be taken to protect all personnel
from these added dangers. Additional diligence must be taken to protect the blade
when in this exposed condition.
6. Adjust CHV to 600 VDC (as seen downhole, DH @ the tool) for additional power
draw requirements.
7. Send Start Cut command. Tool current should ramp up to be within the 0.25–0.35A
range. Watch that the curve MMRPM (Main Motor RPM) increases to and stabilizes
at the designated RPM: 6000 is the usual default.
8. If needed, readjust the CHV to as high as 750V (as seen at the 2010 CHV window) to
a higher range. Check the tool CCV and CHV; it should be around 600 V.
9. Expect some possibility of telemetry dropouts while cutting, but if communications
have been set up properly, you should not see any errors or timeouts. If necessary,
exit the file and re-adjust communications to avoid T/O and NVM errors by re-
training. One good reading every ~5 seconds is good enough to monitor the cut, if
you are experiencing this problem and it cannot be rectified. If the dropouts occur too
often (> 5–10 timeouts per cut), consult the telemetry setup (ECLIPS and Tool
adjustments) for proper communication suggestions.
10. Monitor CHV during the cutting process and make slow, infrequent changes to the
CHV to get it to average about 580–600V (DH). Cable head voltages reaching as
high as 750V on the 2010 Power Supply could be required to maintain 600V on the
cable head. This is typically observed when cutting larger pipe diameters on long

lines in very deep wells. Watch the downhole CHV for about 5 cycles before making
any adjustments; this is to allow time for the tool to receive your sent changes and for
the acquisition windows to update to the new display values. Restart an acquisition
time file if necessary.
11. Observe high or unusual changes as seen on the power supply panel or large
Document is Out of Date - Currently under Review

oscillations on all curve responses. If the main motor RPM drops to near zero and the
2010 current is high (0.6–1.5A), sending a stop command may be wise. This can also
be observed by monitoring changes as represented within the 2010 current window.
If this occurs, it may indicate the blade is starting to stall due to debris or is becoming
dull or has broken, though the new firmware will sense this condition and
automatically make the necessary adjustments. It is often best to predict firmware
adjustments to help with understanding what is occurring during automatic
adjustments. Verify the tool is still properly anchored before issuing any new start cut
Use for Reference Only

commands. Observe all the curves and displays for anomalous or unusual behaviors;
make adjustments as necessary.
12. Changes during the cutting process to the main motor RPM (MMRPM) and/or the
milling disk feed motor (FMMR) may be required, depending on the debris removal
process and material specifications. In fact, we have found making alterations to
these values to be quite common. Use the lookup chart to help determine the optimal
starting conditions for the test pipe. However, over time you will begin to develop
and establish better procedural steps than what are provided here. Slower RPM and
feed rates have been used successfully with unusual materials, such as chrome-plated,
Inconel® and certain hard alloys. Other conditions have called for higher RPMs.
13. At the end of the cut, the blade will go beyond the POD (pipe outside diameter) on
one side before cutting completely through the wall. When the blade goes outside the
pipe, the current will go down and the CHV will go up. Do not adjust the 2010
voltage to go lower in this case, as these oscillations are common and necessary.
Allow it to finish the cut, and be prepared to send the STOP CUT command earlier if
an additional over-cut value is used for the PODX, but your cut is already finished. It
is important to note that during the cut process, a sinusoidal response is commonly
seen initially upon wall contact and again after OD breakthrough, due to non-
centralization of the tool versus pipe and/or due to pipe ID and OD wall variations.
Though these responses can be quite severe, they occur very commonly for almost
every cut.
14. Once the main motor has stopped (and the 2010 current has dropped to 0.12–0.19A)
and the cut is finished, adjust the CHV back down to 500V again and send the retract
arms command to disengage the anchor arms; this can be accomplished in any order.
15. Once the arms have been retracted (HMRPM = 0), stop your recorded file.
16. Turn off the acquisition switch ACT and power down the 2010 (inspect the tool and
blade condition and clean debris from any affected area).
5.3.3 Inner Diameter Detection Process
1. Idle: Waiting for pipe O.D. and cut parameters to be sent down.
2. Waiting for Start Cut command.
3. Updating Diagnostic data. (Voltage, Temp., Current, etc…)
4. Start: Start Cut command is received and main motor is initiated. Rotations increase
from zero to the input cut RPM.

5. Main Motor Current Measurement: Once motor RPM is at target speed, the main
motor runs for ~5 seconds while the average motor current draw is measured.
6. Cut Brass: The feed motor initiates at 50 RPM (5 mm/min for 2570MA) to cut
through the brass insert (it is recommended not to run brass on the bullnose with the
tool in the well; the brass should only be installed for shipping purposes and removed
Document is Out of Date - Currently under Review

prior to any well descents). Though we do not generally cut brass, the firmware
performs the act regardless.
7. Once the tool OD has been passed, if no obstruction or frictional change occurs, the
tool continues at this rate until the brass has been cut through completely.
8. All I.D. detection triggers are ignored during this “Cut Brass” mode.
9. High-Speed Advance (Automatic): Upon completion of CUT BRASS stage, the
feed motor increases to 200 RPM (20 mm/min) until the I.D. of the tubular is found.
Use for Reference Only

10. Motor current during this stage is compared to idle current measured in Step 5 above.
11. Tubular I.D. Detect/Retract: Once the blade touches the tubular I.D. wall, the motor
current will increase.
12. Once the running motor current increases above the idle motor current, the feed
motor will immediately reverse to -1000 RPM. This will pull the blade back from the
wall. This is done to account for de-centralization of the tool.
13. Tubular I.D. Re-Detect: Once the feed motor has retracted from the wall, the feed
motor speed is set to 50 RPM (5 mm/min). Tubular I.D. is detected again using the
motor current comparison described in Step 11 above.
14. Tubular Cut: Once the I.D. is detected again, the feed motor speed is set to the Feed
Motor Speed input by the engineer.
15. The cutting process continues until either the input PODX value is reached, or the
engineer has stopped the cutting process via “Stop Cut” command or a fault condition
has been met.
5.3.4 Well Operational Sequence
1. Set the Main Motor RPM, validate Diameter Disk Size, Feed Rate mm/min and
Tubular POD and Overcut values (PODX) from the MPC Control. It is best to have
this done prior to entering time record.
2. Once “On-Depth” and tied in with the CCL, at the designated cut position, train your
communication prior to commencing cutting operations. Do this before entering the
record mode.
3. Enter Time Record and save all necessary observations in the “Jobnotes.txt” file.
4. Anchor the MPC inside the tubular by sending the “Deploy Arms” command via the
MPC Control Window. Take notice that the 2010 current draw should jump around
0.20A; then settle back to within the range of 0.12 to 0.18A. The hydraulic motor
RPM should be between 850 and 1400 RPM (~1080 RPM, ideally) when the arms
are fully extended and in the “Locked” position.
5. Adjust CHV to 600 VDC (as seen downhole, DH) for additional power draw
requirements. Check that your CCV is working and reads less than the CHV when
the clamp is engaged.

6. Send the Start Cut command. Tool current should ramp up to be within the 0.25 to
0.35A range. Watch that the curve MMRPM (Main motor RPM) increases to and
stabilizes at the designated RPM (6000 is the usual default).
7. If needed, readjust the CHV to as high as 750V (as seen at the 2010 CHV window) to
a higher range. Compare and check CCV and CHV again.
Document is Out of Date - Currently under Review

8. Expect the possibility of some telemetry dropouts while cutting, but if

communications have been set up properly, you should not see any errors of any kind.
If necessary, exit the file to allow re-training and adjust communications to avoid T/O
and NVM errors. One good reading every ~5 seconds is good enough to monitor the
cut, if you are experiencing this problem and cannot resolve it. If the dropouts occur
too often (> 5–10 timeouts per cut), consult the telemetry setup (ECLIPS and Tool
adjustments) for proper communication suggestions. Restart another time file if
necessary. It is not necessary to retract the Anchor Arms or to start over if the file
Use for Reference Only

needs to be exited for any reason.

9. Monitor the CHV during the cutting process and make slow, infrequent changes to
the CHV, so it averages about 580–600V (DH). Cable head voltages reaching as high
as 750V on the 2010 power supply could result in 600V seen on the cable head and
as much as 650 V as seen on CCV. This observation is typically seen when cutting
larger pipe diameters with long lines in very deep wells. Watch the downhole CHV
for about 5 cycles before making any adjustments; this is to allow time for the tool to
receive your sent changes and for the acquisition windows to update to the new
display values.
10. Observe high or unusual changes as seen on the power supply panel or large
oscillations on all curve responses. If the main motor RPM drops to near zero and the
2010 current is high (0.6–1.5A), sending a stop command may be prudent. This can
also be observed by monitoring changes as represented within the 2010 current
window or watching your displays.
If this occurs, and you are past the ID or not near the OD, it may indicate a blade is
starting to stall, due to debris or is becoming dull or broken, though the new firmware
will help sense this condition and automatically make necessary adjustments. It is
best to try to predict firmware adjustments to help with your understanding of what is
occurring during automatic tool adjustments. Verify the tool is still properly anchored
and all curves appear normal before issuing any new start cut commands. Observe all
the curves and displays for anomalous or unusual behaviors; make adjustments as
necessary.
11. Changes during the cutting process to the main motor RPM (MMRPM) and/or the
milling disk feed motor (FMMR) may be required, depending on the debris removal
process and material specifications. In fact, we have found making alterations to
these values to be quite common. Use the lookup chart to help determine the optimal
starting conditions for the pipe in your particular well. However, over time you will
begin to develop and establish better procedural steps than what is provided here.
Slower RPM and feed rates have been used successfully with unusual materials, such
as chrome-plated, Inconel and for certain hard alloys. Other conditions have called
for higher RPMs.
12. At the end of the cut, the blade will go beyond the POD (pipe outside diameter) on
one side before cutting completely through the pipe wall. When the blade goes
outside the pipe, the current will go down and the CHV will go up. Do not adjust the
2010 voltage to go lower in this case, as these oscillations are common and necessary.

Allow it to finish the cut, and be prepared to send the STOP CUT command earlier if
an additional over-cut value is used for the PODX, but your cut is already finished. It
is important to note that during the cut process, a sinusoidal response is commonly
seen initially upon wall contact and again after OD breakthrough, due to non-
centralization of the tool versus pipe and/or due to pipe ID and OD wall variations.
Document is Out of Date - Currently under Review

Though these responses can be quite severe, they occur very commonly for almost all
cuts.
13. Once the main motor has stopped (and the 2010 current has dropped to 0.12–0.19A)
and the cut is finished, adjust the CHV back down to 500V again and send the retract
arms command to disengage the anchor arms; this can be accomplished in any order.
14. Once the arms have been retracted (HMRPM = 0), stop your recorded file.
15. Performing a validation pass below the cut zone is not recommended, as the tool can
get stuck passing through the cut zone if the tubular shifts or moves for any reason.
Use for Reference Only

16. If desired, a pull-out CCL pass can be performed from the cut zone upward.
17. When finished, power down the tool, turn off the acquisition switch ACT and POOH.
18. Once on surface, inspect the tool and blade for possible damage. If possible, clean the
cutting area for additional debris prior to shipping it back.
5.3.5 Automatic Feed Adjustment
To reduce the risk of having the blade becoming stuck/jammed during the cutting process,
or having the tool current draw above the 1.5 Amp operational threshold, an automatic feed
adjustment process has been added to the firmware. This sequence will be initiated if one
of the following occurs:
• Cable Head Voltage (CHV) drops below 425V
• Main Motor RPM (MMRPM) drops below 2000 RPM
If during the typical cutting operation the CHV should drop below 425V (or the MMRPM
below 2000), the blade will be automatically retracted from the cutting wall. This is
followed by the immediate reversal of the feed motor to reduce the main motor load
(Note: This will result in an increase of the CHV). Do not make adjustments to the power
supply at this time.
In OLDER firmware, the acquisition system will then reduce the feed speed value by an
index of 1 (i.e., if it’s at 1 mm/min, it will change to 0.75 mm/min). The feed motor then
proceeds back into the pipe at the slower feed rate. If the CHV drops below 425 (or
MMRPM below 2000) again, the automatic adjust sequence will be initiated again. This
process will self-adjust until the feed motor speed reaches the slowest rate of 0.1 mm/min.
Careful observation of these changes are required to make adjustment, if appropriate.
If the feed rate drops to 0.1 mm/min, the user can select, via the MPC Control window, a
higher feed rate. However, if the cable head voltage falls below 425V (or MMRPM below
2000), the auto-adjust sequence will re-initialize as described above. An increase of the
CHV may be necessary or possibly the tool will need to be re-positioned to a better
location within the tubular.
In version 120 firmware or newer (higher), the acquisition system will simply pull back
the feed arm from the tubular, allowing time for possible removal of debris. The feed
motor then proceeds back into the pipe at the same rate. If the CHV drops below 425 (or
MMRPM below 2000) again, the automatic adjust sequence will be initiated again. This
process will continue and repeat until the problem has been cleared or tool conditions or

adjustments have been made to alter the conditions. Careful observation of errors and
faults are required to make the appropriate tool adjustments.
One possible change that can be made is to the feed rate dropping by one increment lower
via the MPC Control window, or possibly making a higher feed rate, though this is
uncommon. Additional adjustment can be made to the MMRPM by lowering or increasing
Document is Out of Date - Currently under Review

the value; the auto-adjust sequence will re-initialize as described above until conditions
have changed. An increase of the CHV may be necessary if large changes are made or
possibly the tool will need to be re-positioned to a better location within the tubular if the
user can not clear the problem. Tubular anomalies have been known to cause multiple
resets of the blade during the cutting cycle.
Of course, if the blade gets firmly stuck, the CHV will drop below the minimum voltage of
300V. This will create a fault condition, which results in a “hard reset”, which is reflected
as a complete retraction of the blade back to the home position. The tool will not re-engage
Use for Reference Only

if this condition occurs. If the tool is resetting in this manner, it is recommended to

possibly find a different spot in the tubular to cut. Do not make this decision in haste; this
should be done after careful consideration.
Cutting blade damage or loss is possible
• In extreme conditions, it has been observed that the
blade gets stuck and remains in the pipe wall. If this
occurs, it is suggested to try to reverse the blade via
the alternate MPC tool control window, to retrieve
NOTICE and possibly continue the cutting process.
• This should be attempted prior to breaking the blade
by releasing the Anchor arms and coming out of the
well. This would be considered only a last-ditch
recovery method.

Use for Reference Only

Figure 32 – Processing Parameter Status Window

8.1 MPC PROCESSING

8.1.1 Bit Size
The bit size is not something that will affect any part of the cutting process, but it may be
of value if a cut is made to the outer casing string. Enter the bit size value based on
customer unit selection; the default is 200 mm / 7.875 inches.
8.1.2 CCL Floor
The CCL floor adjusts and controls the lower limit of the CCL. It is best to use a floor
value if you do not want to see the baseline artifacts while correlating the tubular to get on
depth. This value is best used during playback mode. Once the floor is removed and
changed you cannot recover the data.

8.2 MPC FILTER CONTROL

Figure 33 – Filter Status Window

The Filter Status routine allows the user to adjust the smoothness of the curves over the
logging interval. Options of medium (default), light, heavy and no filter are available.

9.0 RIG-UP PROCEDURES

See Appendix F for a complete list of items needed for running the MPC tools.
Document is Out of Date - Currently under Review

The cutting blade is sharp.

SERIOUS INJURY MAY RESULT
• The cutting blade and/or the anchor arm
assembly of the MPC instrument must
and NEVER be energized on the surface in an
uncontrolled area.
• The tool must only be anchored on the
Use for Reference Only

or surface when the tool is properly sleeved in a

protective tubing assembly.
• After cutting with the blade in the well,
damaged parts and or debris may have
accumulated in the lower section of the tool.
Do not handle the tool near this point!
• Do not transport or ship the MPC instrument
if any loose debris is accumulated around
the cutting blade. Properly clean the
instrument before shipping it anywhere.

Dangerous hydraulic forces and moving blades

SERIOUS INJURY MAY RESULT
• The MPC instrument has an anchor arm
section capable of exerting over 600 lbs of
force. Beware of finger pinch points,
especially when the arms are closing during
surface checks.
• Use caution around the cutting blade and
anchor arm areas whenever you are in close
proximity of the instrument on surface.

Use caution to avoid severe damage to the head sub

during rig-up.
• Do not drag the tool up the catwalk without providing
additional support; this will prevent the head sub
from rubbing against the drill floor or any part of the
Document is Out of Date - Currently under Review

rig.
• Always support the tool when lifting vertically to
NOTICE prevent rotation or pulling over the head sub and bull
nose.
• Make sure a bullnose is in place. Never rig up
without protecting the head sub.
• Damage can result by dragging any part of this tool
if one person lifts it by one end only. This should
Use for Reference Only

never be done.

Baker Hughes always requires at least two people to lift and support the tool at any time. This is
due to its length and weight (HS&E). Anyone we use or those who might assist need to be
notified to do the same. The tool’s owning location has the responsibility to make sure everyone
who may need to handle the tool is aware of the delicate nature of this instrument.
Be sure to perform a vertical make-up to prevent damage to the cutting head area. Vertical
make-up using the proper MPC tool clamp (MPC2570 Clamping Tool Assembly, P/N
A1003932000, shown in Figure 83 on page 120) is required to prevent deformation of the tool
and to prevent potential internal damage. To avoid damage to the housing and all the mechanical
sections, take care to avoid dropping the instrument or letting it swing into the drill pipe, rig
structure, etc.
It is not recommended to make up the string on the catwalk and pick it up in one piece, as this
action can cause undue stress on the housing and internal electronics. If a vertical make-up proves
to be impossible, be sure to support the tool at all times as it transitions from horizontal to vertical.

The MPC must never cut pipe under compression.

• The pipe must be in tension at all times during the
cutting process.
• The MPC cannot cut in a dry hole. There must be
some type of fluid around the MPC to help reduce
NOTICE the amount of debris that surrounds the cutting
blade tooth surface. This debris if not properly
removed or suspended (via “TUNCUT” grease) will
be re-cut by the blade during the cutting process,
which leads to multiple jam-ups and resets.

If damage has occurred or if it is suspected:

1. Validate with an air cut (with the blade installed) that the arm will extend out in a smooth,
even fashion and that the blade does not wobble or experience a fault or status bit flag of any
kind.
2. Test it against a load (cut a pipe) to be sure that shaft damage has not occurred.

10.0 LOGGING AND CUTTING PROCEDURES

10.1 GENERAL PROCEDURES

The MPC should be run in combination with a pre-run of a Free Point Indicator Tool and a
Document is Out of Date - Currently under Review

Gauge Ring run, to determine that the cut area is free and capable of being placed in
tension and to determine that there are no issues getting to the cut with the tool. The MPC
cannot be used to spud with under any circumstances; cuts should not be attempted
in tubulars unless they are under tension. The CCL should be used to tie into the tubular
and to ensure that you do not cut into a collar or other hardware downhole.
To maximize CCL response, the tool should be run decentralized during logging.
The MPC is a modified 3504 protocol instrument that cannot be run in combination with
other services. The MPC can be run with slip-over centralization when required or sinker
Use for Reference Only

bars above the A3 cable head connection. Caution must be used for these configurations
that restrictions do not hamper the added diameters.
If running centralizers, additional CCL gain will be required and may be difficult if not
impossible to obtain. Correct blade selection; type and size must be made prior to any
deployment into the well. Proper anchor arm selection and use of extensions may also need
to be considered prior to all runs; this depends upon the size pipe and MA selection.
10.1.1 Shop Checkout
Only apply power to the MPC instrument when the tool’s hydraulic arms are in a protective
sleeve; this is especially important for the 2570MA section. Follow the safety procedures
in Section 3.0, Safety.
The MPC uses 3504 protocol and typical RUC addressing support; however, it is currently
a standalone instrument and not combinable with any additional tools. Subset E can be
used for training the telemetry. If a surface “DEMO” cut is attempted, be sure the cut
sample is long enough to cover both the blade and anchor arms. Use of a water bucket or
hose must be used to help clean the cuttings from the blade during the cutting operation. It
is also suggested to never attempt any cuts without a liberal application of “TUNCUT
grease” (P/N 10256081-400 gm or 10149015 GREASE, SPEC COMPLEX, TUNGREASE
CK-2, 1 kg) applied onto both sides of the blade, prior to start of operations.
The acquisition system should launch and attempt to download index 18.0 (depending
upon surface configuration); a 4505 is the recommended surface configuration to use.

10.1.2 Telemetry Tuning Method on ECLIPS

This method assumes prior adjustment of the R121 pot in the EA

section of the 2570 tool on the 2155 Com Controller Digital Board (P/N
Note A3002155000). This procedure is focused on the older version board
set-up, but contains useful process and procedures even for the latest
boards.

1. Select a Conductor Switch Position (MUTI-SNGL-NORM) from the Tool Control

window as described below Figure 8 on page 22 and start the acquisition cycle of
data by selecting an appropriate SwAct.
2. Begin with the transmitter (TX) gain value setting on the TX window on ECLIPS
at ~ -15.
3. Find the lowest TX gain setting that the tool will respond to by doing the following:
– Increase the gain 1-2 steps until the tool just starts responding.
– Decrease the TX gain one step at a time, until the tool stops responding; then go
back up one step.
– Attempt to train. Watch the oscilloscope on the surface panel to see if the tool
responds.
– If the tool responds but you get NVM errors, adjust the RX gain on ECLIPS.
– If the tool does not respond, increase the TX gain one step at a time until it trains
successfully.
4. Once it trains successfully, write down that TX gain value. Use the “Jobnotes” utility
to record your procedures.
5. Increase the TX gain and find the highest value that the tool will train on in a similar
manner as described above. Doing this will give you the operating range of the TX
setting.

6. If the trainable TX gain range is less than 3, switch the Conductor switch setting and
repeat the previous steps.
7. Run with the Conductor switch setting that gives the widest trainable range, whether
it matches your line or not.
8. Once the TX Range has been obtained, set the surface transmit gain value to a
Document is Out of Date - Currently under Review

number that is in the lower 1/3 of the trainable range.

– Example: if a tool trains from -9 to -2 TX gain, the range spread is 9 – 2 = 7.
– The best TX gain setting would be 7/3 + -9 = -6.66 (round it to –7).
9. Perform a similar process to optimize the receive gain in ECLIPS. Note: There is no
need to make RX adjustments, until the TX value has been set and the tool is
properly responding.
10. You can typically look at the scope and set the peak-to-peak amplitude of the receive
signal to 1V as a starting position.
Use for Reference Only

11. Reduce the receive gain one step at a time until training fails, and record that RX gain
number.
12. Increase the receive gain until training fails and record that RX gain number.
13. This time set the receive gain in the middle of the trainable range.
10.1.3 Adjusting the Telemetry Receive Potentiometer in the 2570EA
If the transmit gain range extends below -16 or above 9 or if the TX does not respond at all,
than the tool potentiometer is not optimally tuned in the 2570EA.
The result of a high transmitter gain value above 9 means that the tool pot is tuned for
minimum sensitivity. While this is good for minimizing motor noise pickup and additional
attenuation, when the wireline is deployed downhole it may cause the received signal to be
too small for proper decoding.
Conversely, if the required signal is less than -16, the pot gain may be set too high. This
may work, but it will reduce the motor noise immunity. Optimal tuning includes 0 dB in
the trainable transmit gain range.
Remember to try both multi-conductor and single-conductor wireline types in ECLIPS
Tool Control when determining the best trainable range.
If the tool requires a TX gain greater than 9 or less than -16 or the tool simply does not
respond at all, the pot gain in the 2570EA tool needs adjustment to achieve optimal tuning,
as follows:
1. Open the tool and remove the chassis according to the instructions in the
assembly/disassembly procedures.
2. Power up the tool and set the TX gain to 0 in ECLIPS Rx/Tx Set option:

3. Execute the section of the Checkout procedure (F131144-956, see Section 4.0 on
page 21) involving tuning the telemetry range board of the tool. Adjust the
potentiometer until the amplitude of the signal matches what is shown in the
checkout procedure.
4. Use the surface telemetry procedure and tool pot adjustment procedure to determine
Document is Out of Date - Currently under Review

the best position of the pot and acquisition system for your specific line and system
conditions. If a scope is unavailable, for older 2155 boards the resistance of the R121
pot as measured directly with a Fluke measuring tool between R60 and R59 on the
2155 communications controller board (P/N A3002155000) should be in the range of
98 Ω. (Note: this will vary depending on the revision level of the board.)
An alternate solution can be performed by simply setting the TX gain to zero and
slowly tweaking the adjustment pot until the tool responds with the surface
acquisition system. Be sure to allow enough time for your turn(s) to take effect and
Use for Reference Only

be seen and recognized by the acquisition panel. Suggestions for turns are to use ½ to
¼ turn increments with the pot turned CCW all the way, going CW until the tool
responds, allow at least 3 seconds between steps. Stop adjustments train on the signal
and apply small amount of RTV to hold pot in place once established. This is
assuming adjustments are being made on line and panels which will be used to
perform the cut.
Once proper adjustments have been made for your tool and surface conditions, your
specific turn value should be noted and saved for future use and adjustments. A scope
image is the best approach and you can measure it with short micro-grabber clip leads
connected to pins 2 and 3 of U5 on the Com Controller digital board (P/N A3002155000).
Be aware of your specific board level; this reference refers to some older model boards.
See Section 4.0 on page 21 for the new board configuration set, when the pot adjustment
accepts the signal and responds with a reply back to the surface train your tool.
1. Connect short micro-grabber clip leads to pins 2 and 3 of U5 on the Com Controller
digital board (P/N A3002155000).
2. Connect the clip lead on pin 3 of U5 to the Channel 1 scope probe and connect the
other clip lead to Channel 2.
3. Connect the probe grounds directly to TP22, TP25 or TP28 (no clip lead extension).
4. Set both traces at 500mV/div and DC coupling and 20 MHz BW limiting. Set the 0V
level of both traces to the second voltage division line from the bottom of the scope
screen.
5. Set the time base at 100 µS/div.
6. Trigger on the Channel 1 and at 1.7V (noise reject mode). Set the trigger hold-off to
90 mS.
7. The blue trace (Channel 1) shown in Figure 37 will increase and decrease in
amplitude while adjusting R121. The lighter blue (square wave) trace is the
comparison level and it toggles between two DC values when the blue trace crosses it.
8. Turn R121 to adjust the amplitude of the Channel 1 until the peak-to-peak amplitude
is approximately 1V as shown in Figure 37.

9. The LED DS06 on the com controller (P/N A3002155000) should start blinking
every time the tool transmits.
10. The scope connected to the acquisition panel should display traces similar to what is
shown in Figure 38, where the data request (first packet on the left) is followed by
the tool response. Trace 1 may also show the same pattern.

Figure 38 – Data Request Shown on Oscilloscope

11. Put a small dab of RTV between the potentiometer screw and the body.
If Fluke or auxiliary scopes are not available, the best practices approach to obtaining a
similar result is to turn the pot clockwise 12 to 20 turns (depends of board level and pot)
and return with several turns counter-clockwise. This should place the pot in approximately
the right position; use the scope in the truck/unit and keep turning until the tool responds.
Every line and unit may yield various results. However, the window of communications is
fairly broad with this tool and should allow the user quite a bit of leeway.

Figure 39 – MPC Switch Set for Single-Conductor Usage from MPC Control
On the surface side it is best to start with a TX & RX value both around 0 and place the
setting for signal “Terminator” on. It usually is not necessary to set the 60 Hz Noise Filter.
Once the pot is adjusted in the tool, you can apply a dab of RTV to hold the pot in position.
This should allow the user to use this setting on a number of units and lines. Both Multi
Conductor and Single Conductor lines can be used by placing the Tool Command Switch
in either the MULTI or SINGLE position.
Use for Reference Only

The default when you launch the OCT will always be SINGLE, the optimal position will
depend on line length and panel configuration. It is best to Select MULTI or SINGLE prior
to any communications tests, as these positions include additional features which are not
included in the NORMAL position.

Figure 40 – Tx/Rx Set Window

Figure 41 – Telemetry Status Window

Continuously monitor communications during the entire operation, observing the telemetry
status window (see Figure 41 above). If you are receiving multiple T/O or NVMs, adjust
either the TX and or the RX values. Optimal signals are variable, but generally are in the
range of 600 MV p-p on the TX signal and about 300 MV – 600 MV up to 1V on the RX.
For further details on how to set up proper communications, see setting up telemetry
communications in the R&M documentation (F131144-856), if this procedure is unclear.

10.1.4 Surface Checkout

Tool checkout can start at the surface to establish communication with the tool once on
location. Minor adjustments may be necessary to the telemetry if checked at the shop on a
different unit or system. There should not be any cutting or deployment of anchor arms on
the catwalk, unless tool damage is suspected after a run. If a check is required, be sure the
Document is Out of Date - Currently under Review

anchor arm protective sleeve is in place and all personnel are clearly and visibly away from
the cutting blade section during activation.
If telemetry adjustments are required, try to do them in a protected area to prevent moisture
or debris from entering the electronics of the tool. Only under very short or very long line
conditions should adjustment be required, if the lab setup was performed properly with a
representative line. Care and extra precautions should be taken, as extremely high voltages
are present on the tool boards. When the tool electronics are out of the housing, potential
danger exists. If possible, perform any pot adjustments with the electronics in a dog house
Use for Reference Only

or other protected area.

10.1.5 Zero Tool String in ECLIPS
Before RIH (Run In the Hole), the engineer will need to zero the tool to initially put the
tool on depth. There is an internal CCL in the EA section of the MPC. The distance from
the blade to the center of the CCL is variable, depending on blade and MA selection. In
most cases, since there is no clear marking on the EA to note the location of the CCL, the
engineer should zero the tool on the blade; make a mental note of the distance from the
blade to the bottom of the bullnose. On the Main Menu, select Depth, then Zero Tool
String.

Figure 42 – Zero Tool String Menu Item Selected

This will open the Zero Tool String window. Enter the corresponding depth to zero the tool
at the appropriate depth; we use the blade as the zero point for all OCTs. Be aware when
zeroing on the blade the added length of the bullnose, which will vary based on MA and
blade selection. For depth correlations this distance will need to be known.

10.1.6 General Safety Practices

MOTORING: If motoring is performed at the surface, be sure to keep all personnel and
body parts clear of any moving sections, serious personal injury may result.
ELECTRICAL: High voltages are generated internally, but should be well protected from
user contact under normal operating conditions. Additional concerns may result if removal
Document is Out of Date - Currently under Review

of the EA housing is required for adjusting the telemetry while on location. Follow all local
safety precautions especially if operations are required in Zone 2 or 3 areas.
MECHANICAL: Never let the rotating end of the 2570MA drag against the ground
during rig-up operations, do not use the lower section as a pivot point when lifting the tool.
This action can cause damage to the exterior of the housing and/or the rotating section. The
tool may become misaligned, causing damage to the interior mechanisms and/or
compromising the cutting process. Also, the bullnose is made of softer material designed to
allow it to be drilled in case of loss in the well.
Use for Reference Only

PERSONAL: The weight of the 2570 EA/MA Mechanical Pipe Cutter instrument is
around 141 pounds and just over 18 feet long. To reduce personal injury and tool damage,
handling of this instrument should be accomplished with two or three persons and by
moving the tool in sections. This instrument can be assembled vertically over the well or
horizontally on the catwalk or ground with the tool placed on tool stands.
The 2570/71 MA has a rotating bottom section that houses a milling blade. During
operational surface checkout, the area around the MA should be considered a restricted
area.
The 2570/71 MA has hydraulic anchor centralizer arms that provide the necessary force
required to center the tool during the cutting process in the well. They are capable of
supplying over 600 lbs-force on each arm. Use extreme caution when operating the
instrument for any reason, especially on the surface. The forces involved can quite easily
sever a finger! Always place a protective metal tubular sleeve over the entire length of the
hydraulic arms section during operational checkout on surface.
Never place the tool in a vise without a protective shell on the MA section, as damage can
occur and possible warping or misshaping of the housing is possible. Misshaping will
prevent high-pressure sealing, which will lead to tool failure at higher temperatures and
pressures. Never use a pipe wrench on any part of the EA or MA sections. Special
wrenches are available for use when tightening or removing the sections during rig up and
rig down operations, as well as for R&M repairs.

10.2 HIGH-VOLTAGE SAFETY

Risk of explosion due to ignition caused by

equipment or handling in a potentially explosive
atmosphere
Death or serious bodily injury
• Hot Work Permit required if equipment is

This instrument contains internally high voltage in the EA section. Extreme care must be
taken when the tool is powered with the housing removed. The power supply provides 600
VDC to the EA section. Check all local area operational requirements as Zone 2 and 3
additional precautions may be required. The power supply panel during operations can have

10.3 CUTTING BLADE AND ANCHOR ARM SAFETY

The MPC instrument contains an anchor arm assembly which is capable of over 600 lbs of
pressure; serious injury may result if fingers are placed in or around the area of operation
during the deployment of this section. Additionally, to prevent any injury, there should
always be a protective sleeve placed over this section of the tool to allow the anchor arms
to rest against the I.D. of the sleeve during surface checks. Serious tool damage may result

causing serious and or fatal bodily injury or harm. Extreme caution must be used when
operating this instrument for any and all surface checks.

Working on this tool without its protective sleeve is

dangerous.
SERIOUS INJURY MAY RESULT
• The cutting blade and/or the anchor arm
and assembly of the MPC instrument must
NEVER be energized on the surface in an
uncontrolled area.
or • The tool must only be anchored when the
tool is properly sleeved in a protective
tubing assembly.

As a safety feature, the surface software automatically detects if the anchor/centralizer

arms are deployed; if they are not, the cutter blade will not be allowed to operate.
If there have been any cutting operations, the use of additional safety precautions around
the cutting blade section are required. Serious injury may result due to the additional
buildup of fine cutting particles and/or slices or sliver sections. Do not pick up or clean this
section without proper PPE such as goggles and gloves to prevent eye and/or hand injury.

It is important to realize, especially if doing demonstrations or surface cuts of any kind, that
the tip of the cutting blade can reach temperatures in excess of 1200 °F. Caution should be
taken not to touch the tubular or blade areas immediately after or during any active cutting
operations.

10.4 LOGGING PROCEDURES

A pre-job check list (see Appendix F) should be supplied to the customer prior to any
MPC deployment. It is important that certain information is asked for and made available
to the engineer prior to deployment. Special job-specific needs will need to be known for
proper equipment selection.
The MPC is a single or multi-conductor wireline operated device, configured to perform
these seven basic functions during operation:
1. Tie-in: descend to below cut point and pull up in Depth record to establish a base
CCL pass. Select exact cut location after proper depth correlations are established.
2. Position Blade: descend to appropriate depth; determine relative tool position in the
tubular (CCL), avoiding collars to insure proper deployment of anchors and to insure
execution of the cut within the main body of the tubular.
3. Anchor: deploy an anchor “slip” mechanism sufficient to 1) provide reactive
moment to tool rotation during cut, and 2) provide positive axial positioning to insure
constant path of cutter rotation and minimize material removal.
4. Rotate: power the cutting head so as to produce relative motion between the
deployed cutting surfaces and the tubular.
5. Advance: progressively advance the cutting surface to, and through, the casing body
wall while rotating the cutting head mechanism.
6. Retract: retract the cutting arms and anchor mechanisms following completion of the
cut or if power is lost during operations.
7. Retrieve: recover the tool from the well.

10.4.1 Surface Software Safety Stops

• Advancement stops are in place: The user can set limits on how far the blade will
go out, by entering the proper O.D. and PODX of the pipe. Some operations will
require the blade to only cut an internal tubular body and not damage an outside
string that is in close proximity. There are firmware limits that allow only a certain
Document is Out of Date - Currently under Review

amount of over cut (PODX) past the request POD before automatic retraction will
activate.
• Additional safety features include: At what rate the hydraulic motor, main motor
and/or feed motors will turn or extend and how often any of these areas experience
any error messages. The MPC BIT STATUS offers a window display that provide the
ranges and error status available for user observation and the MPC Control window
can be used for various displays for easy access to any necessary changes.

10.4.2 Logging Speed

There are many factors that affect the CCL signal. Therefore, the correct logging speed for
any given situation cannot be defined. Again, this is best found empirically by adjusting
the speed to obtain accurate location of collars. Typical logging speed to achieve
reasonable CCL sensor response is 30 ft/min (9 m/min). Take note of the average CCL
curve value when going through the pipe. If you encounter any base noise, it may require
you to set your CCL Floor threshold above the default number.
Make note of the CCL value when passing through a collar. This number should be 3 to 4x
greater than the “noise” level observed. The CCL min/max scale values should be the
upper limit value and lower limit value as seen on the display log.
You can use the CCL Gain Index to increase the gain of the CCL to an appropriate level to
obtain a proper CCL Signal. The signal can be gained up to 7 times. From the Data
Acquisition Main Menu, select Tool, MPC: CCL Gain. The default gain is set to 4.
10.4.3 Acquisition System
With the ECLIPS or CASE system properly connected to the wireline, connect the tool,
and apply power to all panels. This should include the host computer, a 2010 DC power
supply, and either a 4505XA or 4503XB (w/ 5771 LCP) and oscilloscope. Use of older
5756 panels and the LCP should be done on a very limited basis, due to power supply
demands and missing chokes and filters necessary for proper communication purposes.
Loss of communications could result in an aborted operation.
When using the MPC it MUST be run with a 4503XB or the 4505XA RAP surface panel,
due to additional power requirements and adjustments made to the communication systems
hardware and software. The use of a 2010 DC power supply is required.
This service cannot be run on a 4501XA/XB panel with a 3765 Line Control Panel. This is
due to the maximum voltage limitation of the 3765 LCP (@ 600 VDC). This limit is lower
than what may be required to achieve the proper cable head voltage during some cutting
operations. To maintain the required 600 VDC at the cable head, as much as 750 VDC have
been observed at the surface panel. This, of course, will be based upon line lengths and
pipe conditions along with tool loads and actual cutting requirements. Additionally, there
are many sources of communication interference because these panels do not have the
necessary chokes and filters to control our signals while cutting.

backs up minimally before resuming the cutting process. The purpose is to clear the blade
of any potential debris that may be trapped in the teeth.
The MERR are primary faulting problems that cause a “hard reset” to be displayed by
flagging the MERR curve (also seen in the MPC Control window). The curves that create
this “fault” condition are always involved with a hard reset; they return the blade to its
primary starting place (the home position). In this state the user must issue a start cutting
command to resume the cutting process.
The reason for halting the operation is to demand total attention from the user to

investigate the reason(s) for the fault condition, because these are more serious conditions.
The extra time is to make any necessary adjustments to the rates to avoid additional
faulting. The MERR curves include bit4.s2, bit5.s2 along with bit13.s2.

10.6 WELLSITE DELIVERABLES

There are two primary presentations available:
• MPC_HYD_ET.log (for cutting operations – Time Only), all curves
• …020a or …020b.log (for tie-in with the CCL – Depth Only)
These plotting templates can be accessed using the *MPC* filter. Below are some
alternative log displays:
• MPC.log contains only the main and feed motors curves and associates.
• MPC_ET.log is same as MPC.log. but is in extended time scale.
• MPC_HYD.log is full log with all curves without an extended time scale.
As an alternate CCL presentation, the basic GR-CCL.log offers a very good template for
use with the MPC tool. It has a mirror CCL on both sides of the depth track, which makes
correlations easy and offers a pleasing display. Alterations for proper CCL scaling will
need to be performed for a matched display.
All other displays and controls are generally for real-time use only. However, “capturing”
an XY-PLOT sometimes goes a long way when explaining particular events to our
customers or for diagnostic review with our technical experts. This can be done and added
to a final presentation, if desired, using a Word document utility from your laptop. There is
currently no way of plotting MPC X-Y displays through the plotting utilities offered on
ECLIPS.

always prudent, however, when operating in higher temperature and pressure ranges to double
check that certain measures and equipment are being used and are in place. Performing any
operation above the service limits described in Section 2.0, Equipment Specifications is not
recommended. Operating above 200 °C will cause tool failure with substantial repair and
maintenance costs. Any operations approaching these upper limits of temperature and pressure
need to be planned and streamlined to minimize time in well under these extreme conditions.
The operating time, for example, at 200 °C is limited to only 1 hour; it is vital that the tool be
monitored closely.
Use for Reference Only

Figure 63 – MPC Temperature Show Window

Observe all temperature values in the MPC Temperature All Show Window (see Figure 63) for
estimations as temperature begin to approach these upper limits. The tool will not operate above
this absolute upper limit. DO NOT go past this limit for any amount of time, no matter how short
a period is estimated: serious tool damage and failure will occur.

13.0 LOG QUALITY CONTROL

Providing examples of various cutting scenarios will give the user a variety of tool responses to
study and analyze. This information is the best form of quality control we can offer. These cuts
range from a standard easily-made cut which takes 10-15 minutes on up to a 2-3 hour cut for
Document is Out of Date - Currently under Review

various exotic metals and pipe conditions. It is vital, though, that all users start to develop a sense
of how the tool handles under differing conditions and materials. There are no set patterns and
often using the same tool in the same material will produce various responses due to anomalies
within the material being cut and the blade entry or location. All conditions are impossible to
control, but as an MPC engineer, your purpose is to limit and control as many of these loose
variables as possible.
Observations of cuts have taken as long as 4-5 hours to complete and have been attributed to the
pipe not being placed in the proper state (under tension). Quite often our customers “believe” they
Use for Reference Only

know all the answers based on estimations and assumptions, but for various reasons they do not
have the conditions they perceive as known, controlled and validated.
For these reasons, we suggest the best, most accurate way of determining downhole conditions.
Not running a Free Point Indicator has proven to be a primary cause of increased cutting times.
Pulling “over” tension on the surface does not always guarantee that the tension is seen at the cut
site. Validation of this fact (using FPI) is one of the only ways to be certain.

13.1 LOGGING SPEED

• Maximum logging speed is 200 ft/min (60.96 m/min), sample rate-based depth
logging.
• Recommended logging speed is 30 ft/min (9.15 m/min)

13.2 CUTTING – REMARKS

Included in this section are:
• Extensive cutting time and conditions
• Tubing conditions and anomalies
• Tool position (i.e., @ cut site)
13.2.1 Extensive Cutting Time and Conditions
It is a fact: to place the tubular string being cut in a “neutral” state, we need to know the
weight of the string and all hardware being lifted. To place it in a “tensive” state, we need
to have the string in an over-pull state; preferably we would like a minimum of 5000 lbs.
over-pull, but have required upwards of 50,000-100,000 lbs or more of over-pull for
various reasons. Predicting and knowing if the string is free of obstacles downhole are two
completely different conditions and scenarios. It is vital for a proper cut to be made using
the MPC tools that we know the downhole conditions and are not just guessing at them
with predictions and estimations.
A simple calculation of known tubular weight can be done by taking the length of the
tubular string (*) x the lb/ft value, add in the weight of all the hardware, jewelry and take
into account possible buoyancy factors, etc. (this is many variables and unknowns), this
will get you somewhat in the ballpark. Even if known 100%, though, these estimations do
not take into account drag or sticking, cave-in or erosional factors, pipe collapse and a
variety of other unknowns. It is vital our engineers are knowledgeable of downhole

scenarios so they can help to properly communicate these concerns and variables to our
customers, in order to get the best cutting results possible for them.
There is absolutely no way the MPC can cut tubulars under a “compressive” state. It is a
simple matter of physics; we cannot push or force a blade into a material that has a higher
yield strength than the amount of force we can provide from our cutting arm. Any amount
Document is Out of Date - Currently under Review

of compression either due to vertical or even torsional forces will hamper our cutting
ability. Eventually, even if we are successful at the start we will reach a point where the
pipe will collapse on the blade which will stick or possibly break the blade and terminate
our cutting operation. Performing a surface demonstration for our customers goes a long
way to convincing and showing them, as well as us, the ability of the tool and its
operational capabilities. Practice makes perfect and the more you practice the better you
will get at making predictions and understanding tool behavior. Do not make the
assumption that you can get all you need to operate this tool simply by reading and
Use for Reference Only

absorbing this document and other written information.

13.2.2 Tubing Conditions and Anomalies
Testing has proven that something as simple as a tong mark made near a collar can hamper
our cutting operations. Be aware of material variables and stay away from areas that may
contain them. In the example of the tong mark, what actually happened in this case, is that
the blade goes from material to air in very close proximity of one another. Here the
material is also compressed (i.e., harder or denser), so it requires a very different load from
our tool versus when it is in air.
Going from one extreme to the other creates oscillations on our currents and voltages
(primarily on MM and feed), which are trying to maintain a stable RPM rate. These
oscillations create spikes which potentially can cause catastrophic failure of the tool. To
prevent damage from these types of spikes, our firmware detects and shuts down certain
operations to protect itself from potential damage. There are high limits, as well as low
limits, but the tool cannot survive in conditions of either type for long periods of time.
It is best to observe and identify when the tool is working “harder” than it needs too. Re-
positioning the tool, though it may set you back some initially, is often the quicker and
better option, especially in this case. As the tong marks are on the outside of the housing,
you do not encounter them until near the end of the cut (85–90% or more complete).
However, if the tool continually resets over and over and sometimes even faults out, it
becomes obvious that this is the scenario you have just encountered.
It might take you 15 minutes to get to this point, but then you could easily spend an
additional hour and a half or more trying to overcome this situation. Pulling up and starting
over offers the better solution, because in a clean, smooth, non-variable material cut, it will
only take from 20-30 minutes for a complete cut from start to finish. For this reason we
suggest not making a cut within 1 to 2 ft. from a collar.
Cut variations can be created from manufacturing material variations and/or internal
anomalies. If a cut is proving to be too difficult, try resetting and pulling uphole. Going
downhole is also an option, as long as conditions permit. An added benefit of this is it
allows retrieval of the anomalous cut site for possible diagnosis and future prevention.
Be cautious of external strings of pipe and/or casings. Cutting into a second string of
material can create any manner of havoc on the tool or the well. Problems can range from
encountering different material make-up variations to creating damage to an adjoining
string or casing that must carry or isolate certain fluids.

Take time to consider all variables and possibilities; consider all that might be done to
prevent potential damage by altering your cut site by a few inches or more. When adjoining
tubulars are in close proximity, selecting a site near a collar (this may assist the process by
providing additional clearance), but not so close as to encounter a tong mark or other
obstruction. It generally will boil down to making a selection at a point which might be the

lesser of two evils.

Make adjustments if and when obstacles are encountered. Take a few minutes, if necessary
in the middle of an operation, to determine alternatives and try changes or adjustments to
the tool’s penetration rate or blade rotation. Experimentation is key, as there is not
necessarily always an obvious or immediate answer available; the more you learn the better
you get.
13.2.3 Tool Position
Do not anchor across a variable internal diameter; this can and will create instability in the
Use for Reference Only

tool during the cutting operation. The tool must maintain a consistent and steady cut site or
additional cutting times and or blade damage could result. Be aware of slippage of the tool
or possible turning of the tool as the cut progresses. We have no direct way of measuring or
knowing if or when a tool has “lost its grip” on the tubular ID. Avoid setting in or around
areas that might be conducive to this detrimental condition.
Avoid cutting near hardware of any kind. Do not attempt to make cuts across two different
materials (such as might be encountered with tubing or casing patch). Having two different
materials raises concerns of differing expansion factors, as well as the fact that they both
will have different tensive or compressive and/or torsional factors placed on them in the
same spot at the same time.
Be aware of external hardware such as scratchers, centralizers, conduits or electrical lines
and packers. Do not cut into valves or gas lift mandrels, avoid any anomalies and
variations. Find the spot that has uniform material to cut through.

13.3 REPEATABILITY
Not required unless requested by the company man.

13.4 LOG ACCURACY

Not applicable.

13.5 LOG QUALITY FLAG

We do not necessarily worry about log quality with this service, as it is a physical result
that is measured, but we do have several fault and error condition flags, for tool quality and
monitoring. These are raised during the cutting cycle to indicate to the user the various
states and conditions of the tool. Based on the various information received from the tool
the user will need to make educated decisions for improvements to the tool or the cutting
environment or to make adjustments or changes that may be necessary to the tubular string
being cut or possibly even change the cut site.
Some of these flags, for example, are MERR fault, which is raised for several fault
conditions (which consists of the bit4.s2, bit5.s2 and bit13.s2 errors — all critical — when
set) and any individual flagged error bits such as bit11.s4 and bit12.s4. It is, however, also
possible to create additional flags locally and add them to the presentations or displays to
monitor user-known specific problems that have been encountered possibly in your past or
to monitor something specific to a certain tool string.

15.0 WELLSITE PROCESSING AND INTERPRETATION

There is no need for additional processing or interpretation of this instrument’s results.
The following are the software updates and changes as of ECLIPS Rel6.1 Update 2:
Document is Out of Date - Currently under Review

• Added support for the newer 2571MA tool and also contains changes and advances for use
with the 2570MA tool; both/all versions of the MPC MA are improved and now supported.
• PDF file fixes and changes — almost all MPC PDF displays have fixes and changes. It is
important to note that a multitude of PDF changes and fixes have been introduced to this
service in this release. Selection and changes to all displays have been made to better
represent and monitor the service, based on new display capabilities and curves. It is
important that the user test and use the new displays and make any personal alterations to
these new files. It is not recommended to save and copy over older PDF presentations for this
Use for Reference Only

service.
• Changed the tool lengths and delays in both the m020a and “b” OCT, to reflect the latest
released revision tool lengths. Adjusted the measure points to reflect the various bullnose
options or MA selection. The default tools and length for the m020a OCT reflects the 50 mm
blade selection and bullnose. It is important to note that the delay will not change, as the zero
point for all tools is the blade (not the bullnose); however, the overall length of the tool does
change. The “a” OCT tool diagram will use the 50 mm length by default, if you are deploying
the 60 mm blade and bullnose, you will need to delete the 50 mm MA tool and select the
60 mm MA tool diagram in its place. It is not necessary to make this change when launching
the OCT to run the service; it is only a change to the tool diagram.
• Added additional tool diagram for 50 mm and 60 mm blade and bullnose options for the
m020a OCT. Added new 2571MA tool diagram for the m020b OCT. Added Tensile and
Compressive Strengths for all MPC tools to tool diagrams.
• Converted pipe OD input from an option menu to a numeric input and corrected the limit
values for each blade size and tool size. A warning message will be displayed if the user
selects or tries to enter a value that is beyond the functional range of the blade or tool.
• Will output correct units converted POD value, whether the tool sends the index or the value
is in millimeter or inches. The way the program functions is transparent to the user, but this
design change is a major software change, which now contains embedded variations for both
MPC OCTs.
– This software change must be accompanied by new EA firmware
– Latest firmware levels are: 130/100/130/130 or later
– MPC Versions: COMM DSP: 130, COMM FPGA: 100
– MPC Versions: MAIN-FEED DSP: 130, HYDRAULIC DSP: 130
• A new curve CCLG has been added to both OCTs; the curve is the current gain step value
that the user selected for the CCL index. This curve was added to the AFF output file.
• The old curve POD is renamed to PODX; this is now a new user input to select or enter the
overcut value, which is designed to stop the tool from advancing past this user-entered end
point. The old curve POD is now the requested cut PODX, as viewed by the MPC tool
control status windows.
• POD logic supports separate index lists for 2570MA and 2571MA. What this means is that
the new software and firmware are backwards- and forward-compatible; however, each tool
series requires the use of a unique and separate OCT, which contains different commands that
are sent to the tool.

• Curve MMRC is now the total number of complete revolutions the cutter has made since the
beginning of the file. Additionally, there is a new curve “REVT” that is a tick mark indication;
it provides a tick mark in the depth track for each revolution the head makes.
• Created new curve MERR (MPC Error) that is an indicator of the motor status lights
displayed in the MPC Main Control window. GREEN indicates nominal, a RED status
Document is Out of Date - Currently under Review

indicates a bit status error has occurred.

• Change the curve name PUSI to PSUI-> This curve is the total power supply current (not
main motor).
• Removed the curve MPC7F. It was meaningless.
• Untagged curves MPCS, MPCCS, MPCRAW, and WTSST2570 from AFF output file.
• For m020b OCT: Added AFF recorded tag to curves MPCS1, MPCS2, MPCS3, and MPCS4.
•
Use for Reference Only

Pipe OD numeric entry is now required in the user interface, which replaces the index option
menu entry (MPC Main Control Window). This value should now reflect once entered the
true Pipe OD of the pipe being cut.
• Added PODX Pipe OD overcut numeric entry to the user interface (MPC Main Control
Window).
• MPC tool reset dialog button added to the Tool menu. This option can be used in place of a
power cycle, if for some reason the tool stops responding to surface commands, to reset all
motors. The reset option is smart enough to maintain power to the Anchor Arms, if this reset
is issued while Anchored Downhole. Any motor that is actively engaged during the issuance
of a reset command will ignore the command — only motors in an idle state will be reset.
• The CCL gain now defaults to 4 (was zero, 0), the command is issued when the OCT is
launched and during any re-initialization command.
• The MPC Main Control Window labels for OD fields contain related curve names, Pipe OD
(POD) and Pipe OD overcut (PODX). The POD is used for all user status displays, and
should reflect the true pipe OD being cut, only within the MPC Control Window. The PODX
value is the user-defined value that the tool will now use to stop all cutting processes.
• A parameter value will be sent to the syslog display representing the user CCL gain anytime a
gain value is changed.
• A parameter value will be sent to the syslog display representing tool status when the PODX
parameters are updated.
• Tool cutting (PODX) parameters sent to the tool now contain the PODX value in place of the
POD value. This is what will be used to stop the cutting processes. It represents the maximum
point that the blade will extend to (End FPRC).
• Cutting progress indicator displays (in the MPC Tool Control display windows) are based on
POD value, not the new PODX value. It is important to note that once the start cut operation
button is engaged, any changes to this value will not be represented in the % Status Display
Window.
• End FPRC value is computed using PODX value in place of POD value.
• The 2571MA OCT tool allows values from 4" up to 7.47" ODs to be entered.
• The 2571 tool uses Mill Disk Feed rate index values of 10-17. This is invisible to the user, but
it is extremely important to know, from the standpoint that the OCT for the 2571 (m020b)
should not be used to operate the 2570 tool and the OCT for the 2570 (m020a) should never

be run to operate the 2571 tool. Due to gearing changes between the two tools, there are
different values used internally; this is automatic if the proper OCT is selected. It sends all the
proper commands from the surface to the tool, based on the MA selection. Never intermix
OCTs with different tools; otherwise, the wrong values and commands will result in improper
tool functionality.

• User Interface (MPC Tool Control Window) settings have previously been recorded within
the RDR and used during playback operations. The new UI settings are again recorded and
the code can detect old versus newer RDRs and update the UI correctly.
• Checks are made to ensure PODX overcut is ≥ Pipe OD and will warn the user; it is
important to note that if the user enters the wrong values, the values will not be sent or
downloaded to the tools. Also, if the values are wrong, the tool will not allow one to issue the
Start Cut command.
• Cut PODX has been added to the red MPC Start Cut “are-you-sure” dialog box. This is
Use for Reference Only

designed as a secondary check to the user to ensure the values that are downloaded are the
ones they wish to use. Once the cutting operations have started, any changes to the POD
downloaded value (those being sent to the tool) will not all be picked up by the MPC Tool
Control displays. Changes done after this point will not be properly reflected in the user
status % windows contained within the Tool Control Window.
• A fix has been implemented for the FMMR (Feed Motor Rate) curve, which was not reading
properly. It requires the same set of upper indices that we use for the “frate” curve.
• The mmbi curve had an incorrect multiplicative factor of 0.0478; it has been replaced with
the correct value of 0.0458 from the specifications sheet. However, the mmbi multiplicative
factor has been changed once more to 0.0916, as experimental data showed this to be more
representative of the real value.
• In OCT m020a, renamed pusi curves to psui
• Internal fix was made to both OCTs for the Accelerometer Calculation, which was not using
the value represented in the instrument specifications sheet.

16.0 ENVIRONMENTAL CORRECTIONS

There is no need for environmental corrections of this instrument’s results. All information
presented is for reference only. It is important for all users to be aware that there may be built-in
inaccuracies of the values being reviewed during the cutting process. The primary purpose of the
Document is Out of Date - Currently under Review

displays is to provide a relative indication of what the tool is doing and where it is during the
cutting cycle.
There is no guarantee that what is being viewed is 100% accurate, but all values and situations
have been tested against reality and for almost every cutting purpose have proven to be very good
accurate results. Our mission is to sever tubular strings that have been prepared and placed under
the right conditions (tensive) and to accurately locate and make cuts in the best suitable locations
for our customers.

tool, which produced design changes. Your best preparation for troubleshooting is to practice with
various tubulars in the lab and develop an understanding of the tool and its curve responses. The
easiest and most compact view of a job is to observe the X-Y Plot, primarily the COMBO
presentation. Study the plot(s) and review the comments below until you can identify all the
various characteristics being described.
The figures below describe a scenario when a blade is stuck in the bullnose after issuing the start
command; immediate fault is issued by tool and observed in the MPC Control window. If the
Start Cut command is issued and the feed arm never extends and the main motor does not spin,
Use for Reference Only

the blade is probably stuck in the home position, due to some obstruction or deformation of the
bullnose. By using the alternate MPC tool control windows, the arm was extended and the blade
was rotated and returned back to the “home” position with a retract command. After several
extensions and even several reversals of the blade, the debris was gone. After 45 minutes the cut
was able to be initiated through the proper MPC Control window.

Figure 66 – MM Plot with Multiple Resets Due to Stuck Blade

In Figure 66, notice the scale change on mmrpm, which shows the reversal of the blade to back-
cut into the bullnose; this helps remove excess material. The cut was able to be completed
successfully as a result of these additional measures. Due to extensive rig-up procedures and
deployment concerns, this was clearly the better option from an efficiency point of view. No
damage was observable on the blade upon final retrieval from the well.

Figure 67 – COMBO Plot After Clear Debris Successful Cut

Figure 67 and Figure 68 show that after 45 minutes of extra time spent removing the problem, a
proper initiation was able to be issued. The cut was done to final completion, in a 5.5-inch packer
element.

Figure 68 – 2571MA Cut Success After Bullnose Clean-Up MMplot

In a deepwater scenario it might be necessary to take extra measures, due to condensate concerns
and a potential need to acclimate the tool to the various temperature changes. Do not power the
tool until below-water subsurface contact is passed. Allow at least 1 hour for the tool to acclimate
to the hotter temperatures, prior to power-up. This extra time is necessary because of possible
formation of ice crystals in the tool electronics, as the tool passes through the cold water.

Figure 69 – 2570MA Typical Cut COMBO Plot in 4.5-Inch Pipe

In Figure 69, observe the ID detection process, which is seen at approximately 4-5 minutes
into the file time. The FMBI (Feed Motor current) in green is seen to progress in a uniform
fashion throughout the cutting process until the end of the pipe is reached. The reason the
current increases through the entire cut is due to additional loading forces, which are
created from the compression of the “fail safe” spring. This spring is designed to return the
feed arm back to the home position in case of power loss.
This is a normal profile which is common in all cuts. There is an additional “fail safe”
spring for the hydraulics, which is designed to return the extended anchor arms. This spring
maintains a uniform load, for valve control and in case of power loss (not shown; see
MPC_HYD.XYPLOT).
Looking at the purple curve, we see the Main Motor current (mmbi); it oscillates early in
the cutting cycle, smoothes out in the middle and near the end oscillates again. This is due
to eccentric effects as the blade enters and exits the pipe, as well as any potential
decentralization effects that may be present.
It is always a good idea to make note of the amount of offset that may be present, by
writing down the time and ID value of the blade as it starts cutting into the ID and once
again the time and ID value as seen when these oscillations start to smooth out. These
notes will provide you with a relative amount of overcut that may be required to cut
through the pipe once the OD is first exited, until the last amount of material is cut due to
tool decentralization effects.
Typically, if proper tension is on the pipe, movement on the accelerometer curves will be
observed first, as well as a jump on surface when the pipe separates, due to the additional
over-pull placed on the pipe, both of which should occur before the PODX value is met.
The FMMR (Feed Motor Rate) was held constant at 1 mm/min for this entire cut. The ID
was seen roughly at 3.75 inches and the OD was reached at 4.5 inches by observation of
the rfdd (disk diameter) curve. The time observed at the end of the cut was around 16

minutes, making the total cut time (4-16) around 12 minutes. When not known via
experimentation, an additional overcut (PODX) of 0.25 inch is a good starting point.

Figure 70 shows all the Main Motor curves. In red we see mmrpm maintaining a
consistent 5200-rpm value. In blue we see the mmbv (Main Motor bus voltage) changing
and making minor oscillations as different loading conditions are encountered through the
cut cycle. We see initial wall contact roughly at 5 minutes, which can also be observed on
the green curve (mmbi).

Early in the process we see the “Brass Cut” and the initial high-speed advance until the

high mmbi values (exceeding 800 mA) and the strange harmonics as seen on the mmbv
and the mmrpm curves. In a situation like this, the tool must be turned in for proper R&M
inspection.
Early in the cut process, multiple resets, high currents and large oscillations caused us to
make a variety of changes and improvements to this tool design. One of these was a change

in the spring design for the motor sections.

Use for Reference Only

Figure 74 – 2571MA High Feed Motor Current COMBO Plot

High Feed Motor Currents as seen in Figure 74 with values going over 1A (note the fmbi
scale change) caused multiple hard resets of the tool; these resets made this cut ultimately
impossible to complete. This test resulted in the above-mentioned spring design changes.
Results typical of this have been seen on actual jobs, when springs do not properly function,
due to sticking as a result of improper maintenance.

17.3 LONG WIRELINES AND CUTTING EXOTIC MATERIALS

For wirelines longer than about 30,000 ft., we have seen that the pipe cutter has difficulty
cutting pipe through a high resistance (~280 ohms or greater). Therefore, if using a 5707
wireline simulator, it may be necessary to change the resistance value to about 100 ohms of
loop resistance. For wireline purposes, this would require that the thickest, heaviest gauge
wireline be used for the application, so appropriate power can be delivered to the tool.
The pipe cutter specification requires less than 400 ohms and the tool can cut some
pipes with wireline up to that resistance, but not necessarily the most difficult metals. It
may cut, but it could take a long time, which causes risk to the cutter teeth. Therefore, be
aware that this tool may not cut pipe with an extremely long, high-resistance wireline in a
short amount of time.
If using a twisted-pair wireline (with power down one conductor and return up the other),
the loop resistance may likely be too high; you may need to test this locally.
Typically, the most preferred wireline that long would be about 7/16" or 3/8" wireline. Of
course, a 40,000-ft. single-conductor wireline will push the limits of 3504 single-conductor
telemetry tuning. All these scenarios need to be tested before going out on location.

17.4 COMMON FIELD QUESTIONS AND ANSWERS

Today we tested the tool. When testing with no load (not trying to cut anything) we
had no problem, but when we tried to cut a pipe (2.44-inch PID and 2.875 POD) the
Document is Out of Date - Currently under Review

pipe didn’t get centralized, even with the arms locked. Is this common?
• Yes, this is a common attribute of the smaller 2 1/8" 2570MA tools. The arms are
weak and do not support the tool weight. This is important knowledge for everyone
to be aware of, so proper compensation (such as centralizers), if necessary, can be
added in highly deviated wells. The tool will not centralize itself, but it does lock and
anchor the tool.
• This is not the case with the 2571MA; however, normally this is not an issue or
concern, as we have plenty of overcut capability, in all conditions, except when
Use for Reference Only

cutting 4.5" OD pipe with the 2570MA. When cutting small pipe for demonstration
or lab test purposes, it is best to set the MA in the tubular and vertically immerse the
entire MA tool only with the umbilical in a bucket or barrel of water. This allows
debris to fall out in a more normal fashion. Be sure the pipe supports the tool; the
arms must be locked and set prior to vertical placement, you must support the tool
independently with a proper tool clamp suspended over the water bath.
Then I followed the SSG. I applied TUNCUT grease and kept a water stream inside
the tube that we were cutting as a lab test. The tube was over the arms (completely)
and over the blade only. When cutting the current kept on 0.24A, but had 0.6A spikes
(it happened every time that the blade touched the pipe) and every spike was followed
by a T/O.
• Having T/Os is not normal. You need to properly adjust your communications. It is
always important to know what kind of acquisition system are you are using. Take
note and understand all panels and configurations involved in the communication
process and remove any opportunities of interference.
As the tool was not centralized in the pipe in the first place, the pipe wasn’t cut
entirely because some of the pipe was closer to the tool and some further.
• That is why we provide the opportunity to add additional overcut, due to de-
centralization effects. These effects are apparent via observations of oscillations, as
seen on either or both the main motor current (MMBI) or the feed motor current
(FMBI) curves.
I increased the POD and PODX on the MPC Control window, but the tool stopped
cutting before reaching the diameter that I had set.
• The POD did not change, so why did you change or adjust this? You should not have
done so. The only thing that needed to be changed would have been the PODX.
However, in your case the tool stopped because the tool issued a fault; did you record
a file while making this cut for you and others to learn from? If not, you need to; you
should have seen (if you replay back the file, you can validate this) that the tool shut
down from a “fault” condition error, either Main Motor (MM) or from the (FM) Feed
Motor. Fault conditions require the user to resend the start command to complete the
cut. Knowing which fault it was and why helps the user diagnose the condition and
know what corrective actions are involved to complete the cut.

• You need to develop your skills in understanding and reading the tool signs. This is
not just a push of the button and walk-away operation. The reason the tool stops
completely and goes back to the “home” position is for the user to look at, think

necessary.
As the current was oscillating, so was the voltage.
• This is very commonly seen at the beginning and end of a cut; this is due to the
decentralization effects you mentioned earlier. This condition can also be seen and
identified when anomalies within the tubular are encountered.
I tried to keep the maximum voltage on 580V, as was shown in the SSG.
• The SSG is a guide, it is not the absolute truth; you should maintain 600V on the tool
Use for Reference Only

cable head. The tool is designed with a CCV (Cable Head Clamp) and CHV (Cable
Head Voltage). You need to supply enough voltage at all times to maintain the needed
600V on the tool. You can do this by placing at least 650V on the CHV to maintain
the necessary 600V CCV to the tool. This is especially important to do and monitor
when the tool is in this “oscillation” cycle (as seen at the beginning and end of the
cutting process, when various materials are encountered).
I was using a 50mm HSS blade.
• The blade chart is meant as a guide and minimum recommendation. Testing has
shown that preferably, we should use and select the VHM (Tungsten Carbide –
Krypton coated) blades in every case.
Why did the cut stop before reaching the Cut OD that was set?
• Look at the bit status show window, see what “error flag” was set and then an
experienced user can tell you why the cut stopped. You have fault indicators in the
MPC Control window and error flags in the MPC_HYD_ET.log window. Which one
of these errors was set? Learn to interpret what you are looking at.
Is it common to have TO when cutting?
• No, adjustments must be made; it is common when using older panels like the 5756
LCP, which was not designed with the necessary chokes and filters that are available
in the 4505 or 5771 LCP.
Is there a way to tweak the communication?
• Yes, refer to Sections 4.1 and 4.3 to learn how to set and adjust
communications. Additional information is also available in the MPC R&M manuals.
Is it okay to have a water stream on the blade while cutting in the lab or for
demonstrations?
• Yes, this is absolutely recommended, and is especially necessary with horizontal cut
situations, which are too heavy to fully immerse in a water bath.
Wouldn’t it wash the grease off the blade?
• No, the TUNCUT grease is especially formulated for cutting operations. During
testing, the grease was applied and multiple round trips into and out of wells were
done with fluid: the grease coating survived every time. Did you apply the grease and
see it wash off? If so your application process needs to be improved.

Is the usage of TUNCUT grease mandatory when testing and on the job or we can use
another grease?
• Yes, it is mandatory for all cuts. There are no substitutes; there are special properties
that are built into this formula to help suspend particles, reduce heat at the tip of the
blade and maintain application.

How many jobs does a 2 kg package last?

• It depends how liberally you coat the blade; the blade should be coated for each and
every run. Buy enough to have plenty extra, as it is cheap and is an excellent assistant
to the cutting process.
How many jobs can a blade last?
• It is recommended to change the blade at every opportunity; they are cheap enough
and vital to all operations. Also, we have found the best results are always with a
Use for Reference Only

brand-new blade. For surface and lab testing, we have found as many as seven cuts
for HSS blades and 14 cuts for VHM blades are possible, but this is not the case for
every material being cut or every blade being used. The only way to be certain is to
change the blade at every opportunity.
What’s the usage difference between the high-speed steel, Tungsten coated with
kryptonite, steel and carbide blades?
• The HSS (High Strength Steel) blade is thinner and less brittle; this makes it stronger
to side impacts. The fact that it is thinner allows it to cut faster and cleaner when used
with certain materials, but it has cutting limitations and dulls easily. Once dull, the
blade simply stops cutting (advancing) and a trip out to change the blade is
mandatory.
• The VHM (or Tungsten Carbide, Kryptonite Coated blades [proprietary information:
DO NOT SHARE]) is our premium blade. It cuts under all conditions, even when
broken, chipped, or used often. For these reasons it is our recommended blade of
choice. The only real problem with using VHM blades is that they are slightly thicker
and extremely hard, which makes them brittle and susceptible to side impacts and
breaking. The thicker design affects the cutting process somewhat, but not enough to
be a real factor. In fact, dropping a VHM blade from just a few feet above the ground
can cause it to shatter. During surface testing, though, observations have been made
where a blade broke in half, due to torsional forces and material variations, yet still
completed the cut.
• This would never be the case with an HSS blade. Dull or missing teeth or breakage of
HSS requires the blade to be changed, if not now, soon. With VHM you might have
extreme blade damage and never even know it until you recover and inspect the tool
and blade for damage back on surface.
The blade would not start turning, in fact the current went way up high and we could
not perform a cut. Why did this happen?
• This typically occurs when an obstacle (such as the bullnose) has been moved,
bumped, pushed or been placed in the way of the blade. The firmware is designed to
perform a check of position when each “Start Cut” command has been issued. This is
part of the calibration process involved in monitoring and knowing where the blade
location is every time the arm advances out. The blade attempts a reversal to
determine its “home” position, prior to extending out. The blade also spins during

this process. The blade must have the freedom to rotate and move forward or it will
eventually have a fault and not go anywhere.
• One possibility to check for obstructions is to go to the manual MPC tool control
windows and issue an advance command without rotating and see if the blade
extends. If it does extend, issue a “freeze” command somewhere along the path and
Document is Out of Date - Currently under Review

attempt to rotate the blade forward. If the blade rotates and extends, you know you
have an obstruction, which has somehow been placed in the way of the blade while it
is at rest and in the home position.
• Using the retract option while allowing the blade to spin might allow cutting or
removal of the problem area. Additional attempts and possibly even a reversal of
rotation might be necessary to clear the pathway of all obstructions. This should only
be attempted as a last-resort option, as potential blade and/or tool damage can
possibly occur. A thorough inspection is mandatory once the tool has been returned to
Use for Reference Only

surface.
The customer has asked me to find TD with the MPC tool. Can I do this? Are there
any concerns?
• Absolutely do not spud, bump or otherwise interfere with the cutting blade process or
area, if it can be avoided. By design, the cutting blade has been placed at the lowest
region of the tool; because of this fact, potential cut failure can result if the bullnose
or surrounding areas are damaged. The customer will not be happy and he will want
to blame Baker Hughes for the lost time associated with it. It is recommended that a
dummy run, sinker bar and/or gauge ring run be made prior to deployment with the
MPC tool, if prior depth determination has not been made.
We were in the middle of a cut in a customer’s well, when our cable head shorted out.
We came out of hole and repaired the short in the cable head. And when we tested
communications with the MPC, the tool would not work anymore. What happened?
• When this occurs, there is a diode on the Clamp Board (P/N A3002299000) that will
need to be checked. When shorts occur on the line near or in the cable head while
power is on the MPC tool, it is possible for a protection diode built into the CCV
board to short out. If this occurs on location, the 2570EA electronics needs to be
turned in to the repair and maintenance lab. Be sure that the short has been repaired
in the line or cable head before connecting the new 2570EA electronics. The clamp
board in the damaged tool will need to be replaced or at the minimum, will need to be
checked for damage to the diode.

18.3 PRE-JOB BASIC OHMMETER CHECKS

Use for Reference Only

Use only a digital multimeter, such as a Fluke Model 87 or equivalent. It is important to

make these checks as often as possible prior to connecting the tools; otherwise, possible
EA or MA damage could result upon power-up. Perform this check anytime a tool failure
has occurred with any part of a shared tool within the string.
1. Measure the resistance between the A3 cable head button (+) and chassis (-) with a
Fluke meter. It should be greater than 100K ohms.
2. Set the meter for diode check and measure the voltage drop from the chassis (+) to
the A3 cable head button. The reading should be 0.7 V to 3V.
3. Test the MA connector plug against the values in the following table.
4. Zero the ohm meter lead resistance before performing this test.
5. Measure the resistance on the pins of the MA bulkhead connector. They should fall
within the ranges listed below. The MA must be at room temperature, as the
resistance readings are temperature sensitive.

Signal and Bulkhead Pin Number Resistance Range (ohms) Actual Reading
Main Sin (Pin 5 to Pin 20) 17–23
Main Cos (Pin 6 to Pin 21) 17–23

6. If everything checks out, connect the 2570 EA to the MA using the A3002598000
umbilical, or directly if the umbilical is not available.
7. Check the MA downhole end and remove the blade, if one is installed.
8. Place barriers around the MA to prevent personnel from touching the MA while
under test.

18.4 OPERATIONAL CHECKS

Check the Mechanical Assembly (MA) for damage, the surface for material abrasion and
that it has the proper minimum O.D. For additional details on the filling instructions, refer
to 130091-953 (2571MA PM3 procedure) and/or 131143-953 (2570MA PM3 procedure).
• Too little oil: evacuate, refill and double-check after 24 hours.
• Too much oil: refer to the appropriate PM procedure.

20.0 TRANSPORTATION AND HANDLING

Document is Out of Date - Currently under Review

The 2570 MPC tool is long

The tool can be difficult to handle alone.
• Each section of this tool is around 9 ft. long.
• Use two people to lift each section in a
and controlled manner.
Use for Reference Only

Use caution to avoid severe damage to the head sub during transport. Unfortunately, since
generally those services are handled via a third-party vendor, Baker Hughes personnel need to
take additional precautions. Never ship a tool without the bullnose, to protect the head sub from
possible damage. Do not ship with the blade installed on the tool. To save time, use only half the
necessary screws only during shipping to secure the bullnose in place. Damage may result to the
bullnose, but it will be substantially cheaper and much easier to replace and repair.
If damage has occurred or if it is suspected, validate this with an air cut with the blade installed
that the arm will extend out in a smooth, even fashion and that the blade does not wobble or
experience a fault or status bit flag of any kind. Test it against a load (cut a pipe) to be sure shaft
damage has not occurred. Prior to running the tool into the well or lifting it on the catwalk,
always be sure a bullnose is in place. Do not ship the tool without protection of the head sub for
any reason.
Whenever we ship from HTC, we always place the bullnose on and also try to wrap the head sub
in bubble wrap prior to releasing it to shipping. Tape a sign “Do Not Drag” over the head sub.
However, based on individual experience, you may decide locally, if your shippers have not
changed their methods and damage has occurred, to build a wooden crate (and save it) for
shipping the tools back and forth to various locations.
Baker Hughes always requires at least two people to lift and support the tool at any time. This is
due to its length and weight (HS&E). Any shipper we use or those who might assist need to be
notified to do the same. Damage can result by dragging any part of this tool if one person were to
lift it by one end only. This should never be done. It is the tool’s owning location’s responsibility
to make sure everyone who may need to handle the tool is aware of the delicate nature of this
instrument.
This instrument should not require any additional special handling or transportation procedures.
All standard precautions and protections need to be considered when shipping these tools.
Currently no special shucks or additional instrument protection are provided or required.
Never handle the mandrel by using a vise or pipe
wrench!
• The tool can be damaged by excessive clamping
NOTICE pressure.
• Always use the equipment specified in the
Maintenance Manual.

Effective Date: 15-Nov-2011

Using this tool in high-temperature zones at 392 °F (200 °C) is restricted to a maximum of two
hours of operation. Note: The specifications are still being developed.
Do not drag the tool up the catwalk without providing additional support to keep the head sub
from rubbing against the drill floor or any part of the rig. Always support the tool when lifting
vertically to prevent rotation or pulling over the head sub and bull nose. Be sure to perform a
Document is Out of Date - Currently under Review

vertical make-up to prevent additional damage over the cutting head area. When lifting, always
use two or three people.
The MPC2570 clamping tool assembly (P/N A1003932000) should be used for all vertical
make-ups (see Figure 83). It can be obtained from Plant 0575 (HTC). It is not recommended to
make up the string on the catwalk and pick it up in one piece: this action can cause undue stress
on the housing and internal electronics. If a vertical make-up proves to be impossible, be sure to
support the tool at all times as it transitions from horizontal to vertical. Never allow the head sub
to slide up or down the catwalk.

Damaged parts and/or cutting debris may be

sharp
Serious injury may result
• After cutting with the blade in the well,
and damaged parts and/or debris may be
accumulated in the lower section of the
tool. Do not handle the tool near this
or point!
• Do not transport or ship the MPC
instrument if any loose debris is
accumulated around the cutting blade. Wait
until the instrument is properly cleaned
before shipping it anywhere.

SERIOUS INJURY MAY RESULT
• The cutting blade and/or the anchor arm
assembly of the MPC instrument must
and NEVER be energized on the surface in an
uncontrolled area.
• The tool must only be anchored on the
or surface when the tool is properly sleeved in
a protective tubing assembly.

APPENDIX C: CHANGING THE 2570MA 2-1/8 INCH CLAMPING ARMS ON THE MPC
The following is the method and procedure for changing out the clamping arms on a completely
assembled MPC Mandrel.
Document is Out of Date - Currently under Review

The MPC must be connected together (i.e., hard connection or jumpered) to an ECLIPS system
IN THE LAB. Do not perform this task in the tool/work area.
This procedure requires the skills of at least two
qualified engineers.
NOTICE • One engineer will be running the ECLIPS software.
• The second engineer will be monitoring the hydraulic
piston/coiled pin position.
Use for Reference Only

C.1 ECLIPS SETUP

ECLIPS is used to send tool commands to the tool to start/stop the position of the hydraulic
piston so that the changing of bent/deformed/old clamping arms can be performed.
ECLIPS has a specific GUI that is needed to perform this task. Once ECLIPS is running,
the MPC OCT launched, and communications with the MPC have been established.
From the main menu, Select Tool, then MPC: MOTOR/SOLENOID. See Figure 84 below.

Figure 84 – Data Acquisition Main Menu Window

This will launch the Motor/Solenoid GUI. The Motor On/Off command will start the
hydraulic pump cycling oil down to the piston, which in turn, moves the piston down and
which will open the arms. The Solenoid On/Off commands will close/open the solenoid
valve, which will freeze/unfreeze the movement of the piston while the hydraulic motor is
running. See Figure 85.

Figure 91 – All Required Equipment for Clamping Arm

C.3.1 Step 1: Position Coiled Spring

During hydraulic motoring, the Engineer #1 running ECLIPS must have

Note
a clear, unobstructed view of Engineer #2.

Once the Engineer #2 is in place, Engineer #1 sends the MOTOR ON command. The
coiled spring pin MUST be in the middle of the hold of the clamp housing.
Move the piston until the pin has traveled to the center of the hole. Once Engineer #2 has
relayed to Engineer #1 the pin’s location, Engineer #1 will send the SOLENOID OFF
command, thus stopping the movement of the piston. See Figure 92 below.

Figure 93 – Removal of Roll Pin

C.3.3 Step 3: Install New Arms

Take note of the direction of the clamping arms when connecting to the
hydraulic housing. The knurled insert is on the uphole end of the
Note
mandrel. The downhole end has a smooth insert. See Figure 87 on
page C-3.

With the old arms discarded, use the Punch-In tool and a hammer to insert the new coiled
spring pins. Do this with all three clamping arms. See Figure 94 below.

Figure 94 – Locations of Both Coiled Spring Pins

C.3.4 Step 4: Cycle Power and Test New Arms

Once all three clamping arms have been installed, Engineer #1 can turn off the power to
the tool. This will open the solenoid value and turn off the hydraulic pump motor. The
spring disks inside the hydraulic clamping assembly will push the piston back up into the
hydraulic housing.
Engineer #2 will replace the metal conduit/tube/retainer over the entire length of the
clamping arms. Engineer #1 will power up the MPC, and cycle the DEPLOY ARMS &
RETRACT ARMS command to the tool.
Engineer #2 should watch for complete extension/retraction for each of the arms.

deployment. It is vital that the MPC engineer has at least this information to select the proper tool
components.

Item Question Answer

1. What are the ID and OD diameter, thickness,
type, grade, material content, tubular weight
(lbs/ft) and drift?
2. What is the depth where the cut is to be

attempted?
3. Are there obstacles and/or restrictions in the
well? If so, please provide all well details.
4. What is the type of fluid(s) in the well? If no
fluid, can water be made available and pumped
down to cut zone?
5. What is the Estimated Downhole Pressure?
6. What is the Estimated Downhole Temperature?
7. Are multiple cuts desired? If so, where and why?

8. Will the well be flowing; can it be shut in?

9. Was a FPI (Free Point Indicator) run done prior,
to determine if the cut zone is actually free?
10. What was the latest tag depth and gauge and
when were they run? The MPC needs current
information, as this tool string cannot spud for
any reason.
11. What is estimated tubular total weight?
12. Will a rig be available on location to pull the
tubing and to place it in tension?
13. How much casing pressure is on the back side?
Will the annulus and tubular pressures be
equalized? This is required for MPC operation.
14. Will the MPC be required to cut any exotic
materials?
15. Are there control lines or other strings of pipe to
be concerned about?
