Wireline Selection
Scope
Proper selection of the wire used in wireline service operations is important for the safe
and successful completion of any wireline job. It is important for the wireline service
specialist to understand the limitations of the wire and the effects that well environments
may have on the wire being used.
General Information
Natural wellbore environments and those induced by man may cause corrosion to the
wireline. This corrosion can be controlled either through chemical inhibition or by
changing to a wireline with a different composition. Recent advances in metallurgy have
led to new types of alloy wirelines that have a very high resistance to corrosion. The
following is a discussion of the normal types of corrosion and the methods used to combat
them, followed by a discussion of wireline minimum breaking strength.
Five types of corrosion will be discussed. These types of corrosion are pitting, general
weight loss, crevice corrosion, hydrogen embrittlement or sulfide stress cracking, and
stress corrosion cracking. Corrosion is caused by the presence of oxygen, acid, carbon
dioxide, hydrogen sulfide, and chlorides, whether naturally occurring or not.
The most common type of corrosion is pitting, which is caused by the presence of oxygen,
acid, or carbon dioxide. Oxygen converts iron or steel into rust or Fe2O3. In the case of
wireline, this can only occur on bright steel wire that has not been used for some time and
is not protected by a coating of oil or inhibitor. As rust appears, pitting occurs which mean
a loss of cross-sectional area. This means a reduction in breaking strength of the wireline.
Of course, all of the alloy steel wirelines are extremely resistant to this type of corrosion.
Acids can still be present in the wellbore during wireline operations, during or after
workover operations. Since wireline operations are of limited duration, pitting during
operations will not be a problem. However, acid left on the wireline will cause pitting to
occur. This can usually be eliminated through the use of an inhibitor placed in a chemical
injection sub (liquid chamber).
Carbon dioxide (CO2) in the presence of water creates carbonic acid which will in turn
cause pitting. CO2 is of great concern to producers and pipeline companies when selecting
their tubulars. It is considered to be of much less concern when selecting wireline. CO2
causes problems in tubulars mainly because the fluid or gas is constantly in motion. When
the fluids are not moving, acid will produce a thin oxidant film which will partially protect
the underlying metal. When the fluids are moving, this film is continuously removed
exposing fresh metal to attack. Wireline is normally done under static conditions and CO2
is not usually a problem; however, if CO2 corrosion is considered to be a concern, the use
of any of the wirelines with more than about 8% chrome (Cr) will reduce the corrosion to
almost nothing. However, if H2S is not present, it is usually considered more cost effective
to use bright steel wireline, accept the pitting that does occur, and replace the wire more
often.
Almost all of the alloy steels are quite resistant to this type of corrosion. However, duplex
steels have been found to be affected during extended tests using boiling hydrochloric
acid. As noted earlier, wireline is never exposed to this severe environment; however,
advances in metallurgy have led to comparably priced wirelines that are much more
resistant to acid. This has led to duplex steel being seldom used for wireline anymore.
Crevice corrosion is an accelerated type of pitting corrosion that takes place in a confined
area, or crevice. This is most often seen in a sealing area such as inside the wireline valve
ram bore or in the o-ring groove on a section of lubricator. This type of corrosion is not
normally experienced with wireline, but it might occur if wireline is allowed to stay inside
the stuffing box packing.
The presence of H2S can lead to hydrogen embrittlement or sulfide stress cracking if
present in sufficient quantities to be considered sour service. Hydrogen embrittlement is
caused by the presence of free hydrogen ions. Sulfide stress cracking (SSC) can be
considered a type of hydrogen embrittlement where the hydrogen ions are released by
H2S. SSC is caused by the hydrogen ions penetrating the metal along the grain boundaries,
thereby reducing the cohesion between the grains. The metal becomes brittle enough to
actually shatter under stress. The process can occur extremely quickly. Therefore, standard
(sweet) service equipment or wire cannot be used for sour service, even for short periods
of time. The use of one of the alloy steel wirelines virtually eliminates any problem caused
by H2S. These wirelines, like the alloy steels used for sour service lubricator equipment,
have a Rockwell hardness of less than Rc22.
Sour service is not determined solely by the presence of H2S. Instead, it is defined by the
partial pressure of the H2S which is a function of both the concentration (ppm) and the
pressure (psi) (see Figures 4.1-1 and 4.1-2). The ppm H2S divided by one million and
multiplied by the pressure equals the partial pressure of the H2S. If the resulting H2S
partial pressure is .05 psi or greater, the well is considered to be sour. For example, a well
with 10,000 psi is considered sour if the H2S concentration is only 5 ppm.
Stress corrosion cracking (SCC) can also cause premature failure of wireline. It is caused
by a combination of stress, high temperatures, and chlorides. Actually, the presence of salt
water or any of the salts used to make brine in the oil field, such as table salt, calcium
chloride, potassium chloride, or zinc bromide, can lead to SCC.The term chlorides is used
only as a general reference.
Metals containing almost no nickel (<2% Ni), or a large concentration of nickel (>40%),
exhibit essentially no stress corrosion cracking (see Figure 4.1-3). Therefore, as noted in
the wireline recommendation chart (Table 3), bright steel wireline will show only pitting
in hot chlorides. Therefore, if H2S is not present, bright steel wireline may be the best
choice. Most of the “mid-range” alloy steels contain between 5% and 30% nickel.
Unfortunately, concentrations of nickel in this range lead to severe stress corrosion
cracking. This means that for sour service, where bright steel wireline cannot be used, one
of the more exotic wirelines must be chosen. Extremely hostile environments containing
H2S, high chlorides and temperatures above 350°F may require the use of a cobalt-based
wireline such as MP35N. This decision must be weighed carefully because of the
extremely high cost, but this wireline has been used under the most severe conditions for
more than 10 years with essentially no corrosion.
Attached as Table 5 is a National Standard’s Wireline profiles. These show the tensile
strength, weight, and stretch for various types of wireline. These values were derived by
actual measurement and are considered the best available. These sheets include at least
one wireline from each of the wireline groups shown on Table 1. All of the wirelines in
each group have very similar compositions (see Table 2) and therefore similar physical
properties. Therefore, the minimum breaking strength shown on the NS profiles of a
wireline in the same group as a wireline not listed will be quite similar. If a more exact
value is required, contact the PSL manager for slickline services.
The maximum amount of straight pull normally allowed for new wire is 60 to 65% of the
minimum breaking strength. For heavy jarring loads, this is reduced to approximately
50%. For wire whose OD has been reduced either by corrosion or mechanical damage, the
value used for minimum breaking strength must be reduced. The wire should be measured
with calipers in two directions and the diameters averaged together. This current diameter
is divided by the original diameter and the result squared. This factor is then multiplied by
the original breaking strength to obtain an estimated current minimum breaking strength.

Notes:
1. Carbon Steel - can be used in any temperature/chloride (salt water) range when there
is no H2S or other corrosive fluids. However, the chlorides will cause pitting-weight
loss corrosion. The pitting would need to be monitored and the wire discarded when
the pitting becomes excessive.
2. 316 Stainless Steel - Austenitic stainless can be used in salt water up to 150-180°F.
Since most wells are hotter than this temperature range and most have salt water
(chlorides), 316 SS is rarely recommended.
3. 6 Moly Stainless Steel - such as 254SMO (Supa 70 equivalent, which has been
discontinued) and 25-6MO (Supa 75 Equivalent) are good for any combination of H2S
and chlorides in temperatures up to 350°F. 25-6MO can also be used in H2S and CO2
wells that have low concentrations (2% or less) of chlorides for intermittent service at
temperatures above 350°F.
4. MP35N - is good for any combination of H2S and chlorides in temperatures over
350°F. As with the other wirelines acids can crack MP35N. However, MP35N will
withstand acids much better than the other wirelines. MP35N is considered the best
wireline available.

1. Sulfide Stress Cracking (SSC) - A form of hydrogen embrittlement which takes place
in the presence of H2S. Single hydrogen atoms, or ions, enter the metal matrix at the
grain boundaries. The presence of the hydrogen between the grains weakens the metal
and makes it brittle. If no stress occurs and the H2S is removed, the hydrogen ions will
eventually work their way out, leaving the metal in its former condition. If stress is
applied while the hydrogen ions are still between the grains, the metal may fracture.
2. Stress Corrosion Cracking (SCC)- In the presence of hot chlorides, corrosion cracking
is greatly accelerated in metals with nickel content between 2% and 40%. If no H2S is
present, it is common to use bright steel wireline since it is not susceptible to SCC. In
extremely hostile environments (>350°F), it may be necessary to use a cobalt-based
alloy such as MP35N.

Though the program does not predict the “used life” with 100% accuracy, the program
will show which wireline sections have been subjected to the highest number of cycles.
Improving distribution of these cycles throughout the wireline is the key to increasing
wireline life. Long term use of the program and periodic testing of used wireline samples
will help improve the accuracy of the wireline management program.
The program, instructions for its use and a sample application can be obtained from the
Slickline Technology group in Carrollton, Texas.

Braided line is recommended for heavy-duty wireline work including difficult fishing
jobs. For low-pressure wells, a swabbing stuffing box is used as part of the lubricator rig-
up to pack-off pressure around the line. For well pressures above 1500 psi, a grease head
and grease injection system is needed to pack-off the braided line against well pressure.

With two-piece slickline units, there is some flexibility in matching an open-loop power
unit to drive an open-loop reel unit. However, there is a difference in where the main relief
and pressure control valve is mounted and how it is controlled. Older reel units have the
pressure control valve mounted in their hydraulic system and the pressure control is
"local" to the reel unit. Newer reel units have the pressure control valve mounted on the
power unit. These newer reel units require that a pressure control pilot hose be connected
to the pilot-operated relief valve on the power unit.
A newer power unit with a remote control relief valve can be used with an older reel unit
that has the pressure control in its circuit. An older power unit that does not have a remote
pressure control valve cannot be used with a newer reel unit that requires this remote
pressure control valve. However, older power units can be modified to operate with the
newer reel units as well as with the older reel units.

As unit 101474238 was originally designed for fast speeds with excellent jarring
response, rather than a steady slow speed, Slickline Technology designed a slow speed
kit for the Single Piece Stainless Steel Unit (below). Technology came up with a solution
to replace the existing motor with a Rexroth motor (101883460) and a gear box
(102493758), both of which are part of slow speed kit 102491811.

Counter Wheels
Heavy-duty slickline units have "four-foot" counter wheels, sometimes called "16-inch"
wheels. Using this size of counter wheel helps to extend the useful life of slickline wire.
Running wire over smaller-diameter "two-foot" counter wheels can reduce the fatigue life
of the wire. For best accuracy, the counter wheel should be in good condition without
excessive wear of the surface on which the wire wraps. Each size of wire requires a certain
size of counter wheel and wheels measuring in feet are a different size than wheels
measuring in meters. Pressure wheels sometimes are different too, depending on the size
of the counter wheel. When the size of wire being used is changed the counter wheel and
pressure wheels also must be changed to the correct sizes. The following table lists the
various sizes of counter wheels and pressure wheels required for each wire size. During
manufacturing, the wheels are marked on their sides with their Part Number or Reference
Number. For checking purposes, the table also lists the nominal dimensions of the counter
wheel.

Note Be sure to use the correct values when setting the AMS.
1. Correct load angle at pulley where load cell is mounted. See Section SL 4.13 for
explanation.
2. Correct size of counter wheel: 2-ft.; 4-ft.; 1.25-m; etc.
3. Correct wire size.
4. Correct rotation. There are two choices. The wrong choice will cause the AMS to
count "backwards".
The rear-most wheel uses a load pin as an axle. A load pin is a device with strain gauges
that sends out an electrical signal in proportion to the load on the pin. The load pin is
mounted in an eccentric housing that is marked to indicate the effective load angle. When
a job is set up, the wire passes over the forward Universal counter wheel (toward the well),
passes over the rear wheel, which is on the load pin, and exits towards the well. The load
pin wheel pivots on the eccentric axis and the effective load angle is indicated on the load
pin housing. This angle is entered into the AMS so that the software can calculate the
correct value of wire tension. (See Section SL 4.13 for description of load angles.) The
AMS uses actual line tension to calculate line stretch. Line stretch is used in the depth
calculation.
Rotation of the Universal counter wheel drives an optical encoder (a counter) through the
“T”-shaped right-angle drive. The other leg of the “T” drives a flexible shaft connected to
a Veeder-Root mechanical counter. This supplies a backup depth indication if the
electronic system fails although the mechanical system is less accurate than the AMS.
Note Because one wheel (Universal wheel) is used for all wire sizes, the mechanical
and electronic depth systems will not agree. Refer to the AMS operating manual for
correlation charts used to correct the mechanical depth readout for the appropriate wire
size.
Under normal operating conditions, wire is held in contact with the wheel grooves by the
tension of the wire and the retainer wheels at the front counter wheel originally were
designed only to keep the wire inside the wheel groove. Under certain operating
conditions, however, tool weight may not be enough to keep the wire in contact with the
groove. If the contact is lost momentarily, some relative movement of the wire with
respect to the wheel may occur. The "slippage" will cause incorrect depth calculations by
the AMS. Slippage may not be apparent to the operator. See the following section, Two-
Wheel Counter Maintenance, for information on adjusting the retainer wheels.
Note Be sure to use the correct values when setting the AMS.
5. Input the load angle correctly so that the AMS correctly calculates he actual line
tension.
6. Correct size of counter wheel - Universal.
7. Correct wire size.
8. Correct rotation. There are two choices. The wrong choice will cause the AMS to
count "backwards".
9. Retainer wheels must be adjusted to maintain contact between the wire and the wheel
groove.
10. The eccentric bushing must move freely about its axis when not under load.

Power required by the AMS panel is 9-30 VDC. The AMS depth panel is fused at 4
amperes maximum current and has reverse polarity protection. If improper polarity
voltage is applied to the panel no damage or possible fire can occur. Loss of power to the
AMS depth panel during operation will not cause a loss of depth data. The panel
continuously stores depth data every 100 milliseconds in a battery-supported memory
device. When power is applied to the panel, the last "Depth" is displayed.
Beginning a job, the Zero Depth switch sets the panel depth display at zero. This switch is
only recognized and read by the AMS when line speed is zero. If this switch is pressed
during a wire line operation the depth display will indicate zero depth. To avoid this
possible loss of depth data, the panel stores depth data until the depth changes from zero.
Note If this switch is pressed in error, do not allow the wire to move. To recover depth
while downhole, press this button again to recall the previous depth display. Do not allow
wire line to move before the switch is pressed again or the depth history will be lost.
The AMS panel is programmed to prevent almost all switches from making setting
changes during wire line operations. Most switch settings are recognized and read only
when depth is equal to zero and/or when line speed is equal to zero. Operator control
switches that directly change the depth display are accompanied by an audible tone when
depressed. These switches are "Zero Depth", "Up Depth" and "Down Depth".
All portable AMS units require separate electronic load cells to measure line tension and
optical encoders to "count" wire displacement. Like the panel-mounted versions, the
portable units calculate the wire depth. Starting with the "counts" of the optical encoder,
the software program takes into account the stretch of the wire and the effects of
temperature upon the counter wheel.

STUFFING
Figure 4.13 - 1
When there is an angle other than 0between the wires, the force on the weight indicator
no longer is twice the line tension. There will be a different correction factor for each
angle. The Martin-Decker weight indicator is manufactured with a correction factor for an
angle between the wires of 90. This factor built into the indicator is 0.7071. At an angle
of 90, as shown in Figure 4.13 - 2, a line tension of 150 lb exerts a force of 212 lb on the
weight indicator. The correction factor of 0.7071 multiplied times this 212 lb corrects the
reading to 150 lb. This correction factor is built in and cannot be changed. If the job
requires a rig-up where the angle is different than 90, the weight indicator reading must
be corrected. The equations at the bottom of Charts 1 and 2 show how the corrections are
calculated.

Example:
Figure 4.13 - 3 shows a situation where the angle between the wires is 60. Chart 1 shows
a correction factor of 1.225 for 60. Multiplying 200 lb x 1.225 = 245 lb. Therefore, the
weight indicator reading should be 245 lb at an actual line tension of 200 lb.

These correction factors are useful when spooling wire on the reel and maintaining the
proper tension. The recommended spooling tension is 20% of the minimum breaking
strength of the wireline.
Example:
For .092 bright steel, 20% of the minimum breaking strength is approximately 309 lb.
When using a wireline unit's own spool off device, the angle between the wire at the load
cell sheave usually is less than 10. The factor from Chart 1 for 10is 1.410. Multiplying
309 lb x 1.410 = 436 lb. This shows that to have approximately 309 lb of tension on the
wire, the spool off drag should be adjusted so that the weight indicator at the sheave
indicates between 430 and 440 lb.

A hydraulic power source is required for operation. For maximum rated output from the
pump skid, the hydraulic supply should be capable of providing 40 gal/min (151 liter/min)
of hydraulic fluid at 2000 psi (138 bar).
The pump skid units use a small triplex piston pump. These pumps can be supplied with
different plunger sizes. The size plunger that is used determines the skid unit's fluid
pressure and flow ratings. Be aware that some units have been supplied with smaller
plungers and those units can develop significantly higher pressures than other units. Check
the skid's Operation Manual and the piston pump nameplate to verify pressure and flow
specifications.
Note Never change the plunger size of a pump skid unit without thoroughly reviewing
the pressure and flow capabilities of the other components, particularly the valves and
piping connected to the piston pump's outlet.

Stuffing Boxes
Scope
Stuffing boxes are considered critical pressure-containing components of the lubricator
stack, so it is very important that they be maintained and tested to ensure proper operation.
General Information
A wireline stuffing box is designed to control well pressure up to working pressure of the
equipment while still allowing the wireline to pass through the packing.
Stuffing boxes are available in sizes and ratings equivalent to the lubricator equipment.
All stuffing boxes must be color coded to reflect their pressure rating and service per ESC-
62 and ESC-63. Also, each stuffing box must have a metal tag with the property number
attached to it. All the scheduled testing and inspection will be documented against this
number per SO1103.
The sealing pressure exerted on the wireline by the stuffing box packing is adjusted using
the packing nut. Manual packing nuts are available, but hydraulic packing nuts are
recommended. Hydraulic packing nuts allow remote adjustment, thus eliminating the
necessity for climbing equipment. Climbing and fall safety is discussed in Section
WL1.23.
Stuffing box packing is sized for only one diameter of wireline. Packing kits are available
for rapid conversion to another size wire (see Technical Section XX.XX). A 16-in. stuffing
box sheave should be used with .108-in. and .125-in. wire. Use of the 10-in. sheave with
the larger wire size will greatly reduce the anticipated life of the wireline. Converting a
stuffing box to the larger size sheave will require the replacement of both the sheave and
the sheave staff.
Operation
When threading the wire through the stuffing box it is important to check the condition of
the upper packing gland, the condition of the packing, and the condition of the wireline
valve rubber which is in the bottom of the stuffing box. Periodically the bearings in the
yoke housing and the bearings on the shaft should be lubricated and checked for wear. If a
hydraulic packing nut is being used it should be serviced periodically. The o-ring on the
quick union should be inspected each time the stuffing box is installed, and should be
replaced if necessary.

The Slickline Stuffing Box forms part of the WPCE stack that consists of primary,
secondary and tertiary barriers, all of which are designed to contain wellbore pressure and
all of which fall within one of our Critical Focus Areas, Barriers.
As there are no two wells with the same parameters the stuffing box packing selection must
be made on an individual well basis. What works on one well may not be suitable for
another well.
For further guidance with regards to elastomer material and its suitability to specific
wellbore conditions, refer to the Seal Selection Guideline.
When we select elastomers for our Wellhead Pressure Control Equipment there are a
number of factors to consider. If the information listed below is not available SWA must
be implemented until it is.
Proper selection, inspection and replacement frequency of slickline Stuffing Box Packings
will ensure their integrity throughout the operation, something that will prevent a
hydrocarbon release and a possible serious HSE incident.
During operations there are a number of controls that can be put in place to mitigate the
risk of premature and excessive packing wear.
The use of a Liquid Seal Stuffing Box is one. This is recommended for operations in dry
gas wells or wells with sour, corrosive or sandy conditions.
The Liquid Seal Stuffing Box is used in conjunction with the conventional Stuffing Box.
Short flow tubes directly under the elastomeric packing enable injection of a lubricant
such as honey oil (wire-line grease) between the packing and the flow tubes; a small
amount of the oil will also help reduce the friction and affinity between the elastomer and
the wire.
This will protect the Stuffing Box packings from wellbore conditions and will lubricate the
wire when retrieving the toolstring back to surface, doing so reducing the likelihood or
even eliminating the risk of a hydrocarbon release due to excessively worn packings.
In addition to the use of a Liquid Seal Stuffing Box, lubricating the wire prior to running
in hole and reducing the running speed during the run will also mitigate the risk of
premature packing wear.
Prior to feeding the wire through the Slickline Stuffing Box it is important to check that all
internal components are free from damage, wear and they are the correct material and size
for the wire to be run. All components must be visually checked periodically throughout
the job and replaced before they become worn. The replacement frequency will be
dependent on the well conditions, depth and number of runs. Failure to replace worn
components will affect the integrity of the Stuffing Box seal, ultimately leading to a
potential hydrocarbon release.
When the lubricator is rigged down, between runs, it is important to inspect the condition
of the packings and if there is any sign of damage or wear they must be replaced.
During operations with H2S present, if working in daylight operations only, at the end of
the working day the stuffing box packings must be replaced.
During this time if excessive wear is observed, consideration must be given to either
changing to a more suitable packing material or reducing the number of runs between the
packing inspection.
In this section there is a list of Stuffing Box Packings, with guidance on their compatibility
with specific wellbore conditions.
A list of RMZ Stuffing Box Packings, along with their compatibility to specific wellbore
conditions, has been added as alternative packing option.

General Information
Prior to performing an onsite hydrostatic test of the lubricator stack, the lubricator must be
filled with water. A purge valve can be placed near the top of the lubricator stack to allow
the air to be purged while the lubricator is being filled. This is especially helpful when
using an extremely long rig-up. The purge valve is placed immediately below the stuffing
box and chemical injection sub. The valve consists of an exhaust port and a plunger which
is moved off-seat by pulling the rope socket up against it. Relaxing the tension on the
wireline allows the plunger to again form a seal. The pressure test can then be continued as
usual. Obviously, this cannot be used simultaneously with a tool catcher.

Figure 4.24 - 1
General Information
Tool Catcher
The tool catcher is placed immediately below the stuffing box and chemical injection sub.
It is designed to latch the fishing neck of the rope socket to prevent the tool string from
falling back downhole in the event that the wire pulled out of the rope socket. The catcher
is composed of a collet-type catcher and a hydraulically operated piston used to retract the
collet fingers and release the tool string. Tool catchers are used most often with electric
line tool strings containing expensive and extremely fragile logging tools.
Tool Trap
The tool trap is placed immediately above the wireline valve. It is manually or
hydraulically operated flapper with a slot that is slightly larger than the wireline. It is
opened just before the tool string is lowered into the well and just before the string is
pulled back into the lubricator. The flapper is intended to prevent any part of the tool
string, or anything fished from the hole, from falling back out of the lubricator.
Figure 4.25 - 1
Description
The lubricator sections are tubing risers which allow the running and removal of wireline
service tools from the well without having to kill the well. The standard stack and optional
equipment lubricator sections shown in the Standard Stack and Options section are 8 ft
(2.44 m) long. Other lengths are available upon request. All lower lubricator sections have
two needle valves for pressure bleedoff.
The lubricator sections of braided/E-line are identical to those used in slickline. While the
middle and upper lubricator sections normally have smaller IDs than with the lower
sections for slickline and braided-line operations, for E-line operations all lubricator
sections normally have the same ID throughout the stack because of the increased logging
tool size. In some cases, lubricator crossover sections may be needed. These crossovers
are not listed in catalog but are available upon request.

Description
The wireline valve is normally placed on top of the wellhead (tree) connector and is
designed to allow work to be performed on the other surface equipment above the valve
while the wireline is in the well. The wireline valve uses rams to close on the wireline and
seal off pressure below the well without damaging the wire.
Wireline valves with a single set of rams are normally used for slickline and in low
pressure [below 3,000 psi (207 bar)] braided line or E-line operations. When pressures rise
above the level at which a single set of rams can effect a seal on braided or E-line, a dual
wireline valve is used. In braided and E-line operations, grease can be injected between
the ram bores to help effect a seal. Dual/triple valves may also be used when working with
different wire sizes on the same wireline unit. Logging operators often use triple or quad
valves for additional safety on high-pressure wells.
Note Hydraulic wireline valves are recommend for STD service above 5,000 psi
(345 bar) and for all H2S service wells.
Wellhead Adapters
Wellhead Adapters
When rigging-up pressure control equipment to a wellhead, there are generally two
methods used. The preferred method is a flanged adapter connected to the uppermost
flange on the wellhead. In low pressure work, a threaded adapter may be screwed into the
top threaded connection on the wellhead.
Flanged Adapters
This is the preferred and safest method of connecting to a wellhead. This connection must
carry the weight of the entire lubricator string, which, if subjected to side loading, can
impose a considerable bending stress on the wellhead adapter.
Flanged adapters are used for through tubing work, 2 1/2-in. ID up to 13 5/8-in. for
adapting to rig wireline valve stacks.
Information needed to identify the particular flanged adapter required, would be:
Note Instead of a pressure rating, the obsolete series number might still be used.
• The top connection, which may be a quick union box or a threaded connection for
large diameter risers.
In general, API type 6B flanges are for 2,000 psi through 5,000 psi working pressure and
type 6BX flanges are for 5,000 psi through 20,000 psi working pressure. 6B flanges
require R or RX ring joint gaskets and 6BX flanges require BX ring joint gaskets.
The use of threaded adapters is limited to 5,000 psi maximum working pressure. Line
pipe, 2 1/2-in. and larger, is limited 3,000 psi maximum working pressure.
• Flanging up to the top of the Hydril is the safest way to rig up. Flanges with a threaded
connection are available in all sizes. Hydrolex adapter flanges with Slimline riser con-
nections have Acme threads with o-ring seals.
• Hydril Adapters have replaced the old “shooting nipple.” These adapters are a section
of riser, usually six feet long, with a flange at the lower end. The Hydril Adapter is set
in the Hydril so that the flange is below the sealing element and the Hydril is closed
around it. Care should be take to not deform the riser.
• The Hydril flange adapter is, by far, the fastest way to rig up for a logging job. A
flange sized to the Hydril has a large ID union box connection up, and a union half on
the lower end of the Bell Nipple is connected to it during drilling. When ready to log,
the union connection is broken out and a section of riser with the same union connec-
tion is made up.

Definitions
WPCE - Stuffing boxes, lubricators, liquid chambers, wireline valves, swages, tool traps,
tree connections, grease injection heads, crossovers, and like equipment used to control
well pressure during wireline operations (Slickline, braided line, or E-line).
H2S Service - Sour gas - Wells are considered sour if the H2S partial pressure is .05 psi or
above. The parts per million of H2S must be used in a calculation that involves the
maximum down-hole pressure to calculate the “gas partial pressure.” Multiply either the
mol percent or volume percent H2S in the gas by the maximum pressure; for example: a
well producing a gas containing 10 ppm H2S at 5,000 psi would result in an H2S partial
pressure of 10/1,000,000 x 5,000 psi, or 0.05 psi. A well producing 0.001 mol % H2S in
5,000 psi gas would also represent 0.05 psi H2S partial pressure, because 0.001 x 0.01 x
5,000 psi = 0.05 psi. The significance of 0.05 psi partial pressure H2S is that it is the cutoff
for either sweet or sour service. Wells producing 0.05 psi H2S partial pressure are, by law
in Texas and per NACE, sour; H2S partial pressures less than 0.05 psia are sweet.
Standard (STD) Service - "sweet" wells, standard wells, those not considered H2S or
Cold service.
CO2 Service - CO2containing well. No special WPCE is built for this service. STD
service WPCE is used for CO2 Service.
Cold Service - Temperatures below - 20F (-28.9C). Any WPCE used below -20F must
be rated for Cold Service. New equipment should be ordered with a -75F (-59.49C)
temperature rating, though existing cold weather equipment may be rated for a higher
temperature. See Technology Bulletin CPE 96004 for further details.
High Temperature Service- above 250F (121.1C). ES-I-* and ES-T-* Specifications
- these are Halliburton D/FW Center specifications. Equivalent Halliburton alliance
partner specifications or IMS specifications from other Halliburton centers are also
acceptable.
Equipment Selection/Safety
• On all wireline jobs, the WPCE selected for use must be designed and built for the
intended pressure and service.
• An assembled unit cannot be rated or used at a pressure higher than the rated working
pressure of the lowest pressure rated item in the assembly.
Elastomer
1. STD or CO2 Service - Nitrile (Buna-N)
2. H2S Service - Fluorocarbon (Viton or Fluorel)
For Fluorocarbon o-rings purchased from D/FW Center, 91QV@---M series should
be used for quick unions or other equipment that may be experiencing difficulty
sealing pressure. The 91QV@---H series o-rings are too hard to effect a seal in
many cases (see Engineering Bulletin 355 for details).
3. Cold Service - Low Temperature Nitrile (see Technology Bulletin CPE 96 004 for
further details).
4. Temperature Service
5. STD or CO2 Service - 80,000 to 110,000 psi minimum yield; screw type swages (tree
connections) must be no less than P-105 grade (105,000 psi minimum yield material).
Rockwell hardness must be 36HRC (Brinell 341) or less.
Note CO2 produces a weight loss corrosion that should be monitored. WPCE built of
4130/4140 material will have an equal amount of weight loss corrosion whether the
material is heat treated for STD or for H2S Service. WPCE used periodically in CO2 can
typically be used for years without excessive corrosion problems. For extended use on
CO2 wells, more frequent inspections of the WPCE should be made until the rate of
corrosion is known. If little corrosion is found, the frequency of inspection can be reduced
to that listed in this manual.

General Information
Slickline
Slickline normally travels horizontally from the wireline unit to the hay pulley/weight
indicator at the base of lubricator. It makes a 90° turn around the hay pulley, travels up the
lubricator, and makes a 180° bend at the stuffing box to pass into the lubricator.
For .092-in. wireline and smaller, a standard 7- or 8-in. hay pulley is used. For the larger
sizes of slickline, a 16-in. hay pulley is recommended. Use of the small hay pulley with
.108-in. and .125-in. wireline will cause the wire to be overstressed and can lead to
premature wire failure.
More unusual rig-ups may necessitate the use of several hay pulleys to achieve a 90° bend
at the weight indicator and to prevent the wireline from scraping on obstructions. If a 90°
angle at the hay pulley/weight indicator is not possible, a correction factor must be applied
to the weight indication. This can be found in section WL1.20.
Several operational difficulties with the 16-in. hay pulley have recently been addressed. It
has been impossible to use a standard line wiper with the large hay pulley. An adaptor
(part # 46PA16204) is now available which allows the use of the standard slickline wiper.
Another problem has been noted with the large hay pulley that usually occurs during
downward jarring. As the wire becomes slack, the hay pulley and wire will “flop” against
the tree or deck. When tension is again applied, the wire shows a tendency to slip off of the
wheel and can become kinked around the shaft. A hay pulley stand (part #46PA16205) is
now available that will prevent the pulley from laying over on its side. Care must be taken
to prevent the stand from interfering with the weight indicator.
Braided Line
Braided line is most commonly run using a floor sheave and a crown block sheave. Most
logging units have a weight indicator built into the levelwind assembly. This eliminates
the need for a weight indicator to be attached to the floor sheave (hay pulley). A crown
block sheave is commonly used instead of having a sheave attached to the lubricator. The
wireline can be used to pick up the lubricator. This arrangement also allows heavy jarring
without any danger of bending the lubricator. See Figure 4.34 - 2.

The slickline rope socket provides a means of connecting to tool string to the end of the
wire.
For slickline operations there are two basic types of rope sockets available:
Figure 4.36 - 2
The knot-type rope socket (Fig. 4.36-2) is what we will call the traditional type, because it
has been around the longest. In this type of rope socket the wire is threaded through the
body, spring and spring support, wrapped around a disc, then wound around itself with
tight wraps (Fig. 4.36-3). For typical slickline operations, the operator would make
between 7 to 14 wraps to complete the knot.
Figure 4.36 - 3
However, there are situations (crooked tubing, wire fishing, etc.) where the wraps would
be reduced to 1 ¾ to 2 wraps. With only 1 3/4 to 2 wraps, the operator could pull the wire
out of the rope socket if the tool string became stuck.
The no-knot (Fig. 4.36-4) rope socket is quickly becoming the favored method of
connecting the wire to the tool string for two reasons.
The strength of this type of rope socket is due to the reduction of tight
bending radii.

Note When selecting the stem size, consideration needs to be given to the tubing size
and the cutter bar that might be used to cut the wire at the rope socket. If the cutter bar and
the stem can fit side-by-side in the tubing, when the cutter bar is dropped, it might fall
along side of the tool string creating a very difficult fishing operation.

Some operators will not use knuckle joints because they feel that it
will create a weak link in their tool string. If a knuckle joint is not
properly cared for, it could easily part.

screws into the socket, the connection has a thin wall on the socket. A

operational condition. Careful placement of the pipe wrenches to
keep them off the thin wall of the socket, removing the roll pin and
socket to clean and grease the threads are part of the maintenance
required. The condition of the socket should be inspected before each Figure 4.39 - 1
use to determine its condition.
Otis Knuckle Joints have a special ball and socket design allowing angular
movement between the jars and the running or pulling tool to help align them
with the tubing. Knuckle joints are important if the tubing is corkscrewed and
when wireline work is done in a directional hole. In these conditions, joints
are used at every connection in the tool string. Where stem and jars will not
align or move freely, tool operation may be impossible; however, the knuckle
joint inhibits the wireline tools from hanging up.
Otis Jars are available in mechanical and hydraulic types. With a set of
mechanical jars below the stem, the weight of the jars and stem can be used
to jar-up or down by pulling and releasing the wireline. A Halliburton
Wireline Specialist can easily feel the jars and manipulate the wireline.
Hydraulic jars are designed to provide jarring action in wells in which it is

CN03563
difficult to obtain good jarring action with mechanical jars. Hydraulic jars,
which allow an upward impact only, are usually run just above the regular
mechanical jars. They require careful maintenance for maximum use in the
tool string. Jar operation is monitored by a weight indicator. Otis® Otis®

Otis B Blind Box serves as the impact point when downward jarring

Mechanical Jars
With the mechanical jars attached below the stem, the weight of the stem can be used to
“jar” up by quickly pulling up on the wire to rapidly “open” (extend) the jars to create an
upward impact. To jar down, the wire would be pulled up slowly to extend the jars and
then released quickly to allow the stem to fall, closing the jars and creating a downward
impact.
Hydraulic Jars
The Hydraulic Jar (Fig. 4.40 - 1) is designed to provide upward jarring impacts under
conditions where it may be difficult or impractical to obtain adequate upward jarring
impacts with the mechanical jars.
Hydraulic jars are capable of providing an upward jarring impact only. They do not
provide a downward jarring impact. When used, the hydraulic jar should be installed
immediately above the mechanical jars in the slickline tool string. The hydraulic jar is not
intended to replace the mechanical jar in the slickline tool string.
upward at a constantly accelerating velocity until the top shoulder on the piston strikes the
stop in the upper end of the body. This transmits an upward jarring impact to the tool(s)
that are below the hydraulic jar.
After the upward jarring impact has been completed, the wire is slacked off to allow the
weight of the slickline stem to "close" the hydraulic jar. During closing, as the piston
enters the cylinder, the valve assembly in the piston is moved off seat to permit rapid
displacement of hydraulic fluid from below the piston to above. When the mandrel/piston
assembly has completed its downward travel, the valve in the piston is closed by a small
spring and the jar is ready for the next upward jarring impact.
The slickline operator can control the intensity of the upward jarring impact of the
hydraulic jar by increasing or decreasing the amount of tension (and the resulting stretch)
that is pulled on the wire.
One of the problems associated with the use of hydraulic jars is that they can "gas up" and
created a shock absorber that hinders jarring. Understanding the operation and function of
the components of the hydraulic jars and using good redress practices can reduce the risk
of getting gas into the jars.
When the hydraulic jars enter the wellbore, a pressure differential is created if the balance
piston does not move. The fluid inside the jars will remain at atmospheric pressure. Then
when the mandrel/piston is pulled out to effect an upward jar the differential is greater.
This pressure differential, causes rapid deterioration of the seals and gas enters.
Pre-testing the hydraulic jars on the surface, and visually inspecting the movement of the
balance piston, will assure longer use.
Spring Jars
Spring jars (Fig. 4.40 - 2) were developed in response to the “gas up” problems of the
hydraulic jars and to increase the effective stroke thereby increasing the impact forces
downhole.
Spring jars uses a stack of disc spring washers, that are fully
adjustable giving them the ability to simulate the function of
hydraulic jars without the risk.
Figure 4.40 - 2
SL 4.41: Accelerators
The accelerator is used in conjunction with the hydraulic or spring jars, primarily, when
unseating and retrieving unusually heavy sub surface devices from shallow depths in the
well.
At shallow depths and deeper depths in highly deviated wells, the amount
of “stretch” that could be pulled in the slickline to activate the hydraulic
jar would be minimal. Slickline riding along the tubing wall can cause a
change in the effective stretch of the wire. Additionally, this load applied
to the slickline at shallow depths would tend to either break the slickline
or cause it to pull out of the slickline socket.
When a strain is pulled on the slickline, with the accelerator in place, the
spring in the accelerator is compressed a given distance. The distance
that the spring is compressed is greater than the distance that the
mandrel/piston assembly of the hydraulic jar must travel when moving
from its "closed" to its "open" position. By maintaining a constant
tension on the slickline, the compressed spring in the accelerator tends to
accelerate the upward speed of the mandrel/piston assembly of the
hydraulic jar when it activates. This delivers an upward jarring impact to
the tools below the hydraulic jars.
CN03566
In effect, at shallow depths, the accelerator simulates the wire "stretch"
Otis®
that is normally required to operate the hydraulic jar. The accelerator also Accelerator
provides a cushioning effect that helps to avoid either breaking or pulling
the wire out of the slickline socket at shallow depths. At deeper depths
the accelerator can increase the speed of the impact to generate more force.

Service
The Kinley power jar was adapted from the Kinley tubing perforator, which has given
safe and dependable service in thousands of wells.
It hits hard enough to cut out the bottom of a 2-7/8-ft and is estimated to hit 40 times
harder than Bull Plug any Mechanical Jar.
Uses
• knock a stuck choke loose
• knock out bridge plug
• knock out flapper valve
• shift a sliding sleeve
• drive a spear into tangled wire
• knock loose stuck tool string
• knock out packer ball seat
Advantages
• Tremendous savings possible by avoiding workovers. One job saved a customer over
$2,000,000.00.
• Power jar does not anchor itself and can be pulled and reloaded after each shot.
Figure 4.46 - 1 • Force of blow can be varied to suit the job by changing to a more powerful cartridge
for each shot.
• Hits a harder, straighter blow, even in deep wells, as compared with any mechanical
jar propelled by gravity and impeded by well fluids. It is less apt to batter the Fish off-
center.
• A hammer, chisel, cutter, etc., can be used to perform different jobs. These
attachments remain a part of the tool and are pulled with the jar.

1. The first step is to cover the well hole so that none of the small parts can drop into it
while the cutter is being assembled on the measuring line.
Figure 4.47 - 1
2. Cut 1/16-in. brass welding rod to 4-in. long, and push it clear through the two
lengthwise holes in the slipper. The upper end of the slipper may be identified by the
rounded (crimper) edge where the slot comes to the diagonal end.
3. Put the slipper on the measuring line so that the measuring line lies in the back of
the slot.
4. Put the crimper on the measuring line in the same way, above the slipper, and bring
the two pieces together, pushing the 1/16-in. brass shear pin up into the crimper, and
out the far side just enough so that it can be crimped down into the recess for it.
5. Screw the set screw into the tapped hole at the top of the crimper until it is tight.
6. Put the knife on the measuring line in the same way, below the slipper, and
bring the pieces together, pushing the 1/16-in. brass shear pin down into the
knife. Crimp the end of the shear pin slightly, and screw the set screw in all
the way. This completes the sub-assembly.
7. Put the body on the measuring line and push the subassembly up into it.
8. Line up the 1/16-in. shear pin hole which goes across the knife with the correspond-
ing 1/16-in. shear pin slot which is to be found in the last 3 or 4 threads at the bottom
of the body. Push another 1/16-in. shear pin through and cut it off so that it won't
interfere with the threads.
9. Put the bottom cap on the measuring line, below the body and sub-assembly, and
screw it tightly onto the body.
10. The cutter is now ready to drop into the well. If the well is not full of fluid, run in a
few barrels ahead of the cutter to break its fall, and to be sure it doesn't cut the line
when it hits fluid. Drop the cutter.
11. The cutter will cut the measuring line when it hits the rope-socket. It will also crimp
the end of the line and clamp onto it at the same time. When the line is brought out
of the hole, the cutter will be on the end of it.
Figure 4.47 - 2
Advantages
1. Economical and efficient. Most jobs in tubing take only an hour. Compare this with
the usual long time and heavy expense of pulling the line in two, and then cutting the
remaining line, joint by joint, as the tubing is pulled.
2. Helps to save the fish as well as the line. When the cutter rests on the fish and cuts the
line just ten inches above it, the stub is short and it is possible to fish for the stuck
tools.
• Cuts in casing, tubing, or coiled tubing (1-in. OD or larger).
• Cuts in drill pipe (1-7/8-ft minimum OD. or larger).
• Cuts sand line any size up to, and including 1/4-in. 1 1/2-ft OD tubing,
1/2-in. 2 1/16-ft OD tubing, 9/16-in. 2-3/8-ft OD tubing, 3/4-in. 2-7/8-ft OD

3. Optional electronic programmable timer designed to fire the sand line cutter after a
Figure 4.48 - 1 pre-selected interval.
Operation
The cutter can be lowered or dropped into the well. A groove down one side keeps the
line in front of the knife. After the cutter rides the stuck line down to the top of the rope
socket, it is fired by a drop weight or timer. It is the powder charge that drives the wedge,
which forces the knife to cut the sand line.
In 2-3/8-ft tubing (or larger) the drive wedge that operates the cutting knife also forces a
crimper (not shown) to clamp the line against a sleeve. This crimper allows the cutter and
the drop weight to be recovered on the end of the cut line, which can eliminate the fishing
job (which may be necessary in smaller sizes of tubing).

• Surface to be jarred against – hard or soft tag
• Lessons learned
Shear pin breaking force – Shear pin breaking force can be obtained by taking the
product of the shear pin cross-sectional area and the material's Ultimate Shear Strength
from a straight pull. The values shown in Table 4.49-1 are the Ultimate Shear Strength
ratings for commonly used shear stock material.
Single or double shear face – Shear pins can be either single shear or double shear
(shown below). If a shear pin extends through a core touching either side of the sleeve,
then the pin is said to be in a double shear, and thus the force required to shear it is twice
that of a single shear. Double shear face is the most common condition in slickline
shearable tools.
To produce a pure and smooth shear in materials can be very difficult. The cutting edges of
the shear face need to be sharp with the shear stock closely supported. If the shear force
required is critical in determining the success of the operation, then a pull test should be
conducted prior to the run to confirm any figures. However, Table 4.49-2 (below) can be
used as a guide:
In a given well, if you are concerned about your ability to shear a pin via downward or
upward jarring due to inhibited jar action, start conservatively with a brass or aluminum
pin.
When a pulling tool is being run to either set or retrieve a flow control device, or to
retrieve a fish, it is recommended the pulling tool is pinned with aluminum or brass, unless
it can be confirmed from a previous run the pin in the tool can be sheared without too
much difficulty. In the event the flow control device or fish cannot be pulled free, this
should enable the pulling tool to be sheared, retrieving the toolstring to surface while
leaving a clean fishing neck for future runs. The same methodology can be followed while
shifting an SSD or retrieving a gas lift valve.
Note Although aluminum has similar shear strength to brass, if the cutting surface or
the tolerance between the two cutting surfaces is worn, an aluminum pin can smear
making the shearing process more difficult.
Although the decision tree shows the cautious approach, with all runs having brass pins,
for a number of reasons, including but not limited to the following, a steel pin may be
preferred over a brass or aluminum pin:
• Confirmed hard surface which will allow the steel pin to be sheared.
• Good jar action obtained in previous run and deemed sufficient to shear a steel pin.
• Pin sheared prematurely when working toolstring through restrictions during previous
run.
• Weight of toolstring would cause the brass or aluminum pin to shear prematurely.
• Risk of pin shearing prematurely leading to additional rig time.
Each run should be reviewed with the risk assessed on an individual basis, taking into
account the effect of deviation, fluid viscosity, etc. Changing the spring jar setting, adding
stem, integrating accelerators or roller systems into the toolstring can all greatly increase
the impact force generated at the toolstring, ultimately increasing the mechanical shock to
the shear pin. Additionally, the tool BDMI should be used as a reference regarding correct
tools to be run in the correct order (for example, R-series before S-series).
In instances where more than one shear pin may be in place to help facilitate stronger
manipulation of downhole tools without prematurely releasing the tool being deployed,
consideration must be given to the capability to shear both pins in downhole conditions
versus the expected force required to manipulate the deployed tool without shearing to
release.
Note All toolstring components shall be functioned prior to running in the well. This
will ensure the tool operating envelope and specifications are verified to meet the job
requirement. Consideration should also be given to the physical condition of any shear pin
previously run in the well. If the shear pin is not replaced prior to each run, any loads
applied during previous runs may cause a reduction in shear pin value with premature
shearing a possibility
Note When replaced, shear pins should be cross center punched to ensure they stay in
place during the running operation and filed flush with the OD of the tool to ensure the
tool OD is not affected.
*** When deciding to change from a jar up to shear pulling tool to a jar down to shear
pulling tool, it is recommended to first run the pinned up pulling tool with the keys or dogs
removed to ensure the tool will shear and release from the flow control device in the event
it is latched. If the pin can be sheared, the operation can continue with the pulling tool c/w
dogs or keys.

Conversion Factors
Multiply By To Obtain
Downhole Pressures
To find the downhole pressure, multiply the surface pressure by the Correction Factor
corresponding to the well depth and the Gravity of the gas.
Gas Table
To find the pressure at the bottom of a column of fluid, multiply the depth of fluid by the
Pressure Gradient and add the result to the pressure at the surface of the fluid.
*For heavier fluid weights, pressure gradient in psi/ft = 0.05195 x density (lb/gal) or
pressure gradient in kPa/m = 22.626 x density (kg/m3), 1 lb/gal = 119.841 kg/m3
