 Cardinal Rules of Pipe Recovery

Pipe Recovery

1. Free Point: Pipe is free or stuck. Always leave free pipe above the stuck point if you
intend to fish this well. One or two joints above the stuck point is recommended.
Always check torque and stretch.

2. Chemical Cut: (Hypergolic) Must have liquid present. Does not work well in heavy
muds (>15 PPG). Bromide Triflouride freezes at 48°F and boils at 257°F. Very poor
track record in attempting to cut greater than 0.450” wall thickness.

3. Jet Cut (Super Cutter): Cut in centralized area to avoid casing damage.

4. Back-off: At second free connection above the stuck point.

5. Severing Tool: Recommended for open hole use only. This tool will damage
concentric strings. GOEX recommends firing in the tool joint or coupling if
attempting to sever pipe not drill collars.

6. Freepoint / Horizontal Wells: Torque including left hand torque and stretch readings
a must in order to insure back-off.

 Mud Properties for Fishing

Weight - Sufficient to maintain well control and control sloughing shales and
water flow. Fresh water weighs 8.3 ppg.

Viscosity - Fresh water has a funnel viscosity of 26. In a drilling operation

(10,000’ or less), the viscosity will probably run 32 to 36. Prior to
logging, high viscosity sweeps are normally made with a viscosity in
the 70 range. In deeper wells or unconsolidated sand the viscosity
should be four times the weight.

Velocity - Minimum velocity with drilling mud in open hole is 100 ft./min. by the
drill pipe. With clear completion fluids, minimum velocity is 150
ft./min. In a milling operation, the velocity should be 200 ft./min if
possible.

Yield Point - A low yield will allow the mud to break down at the cutting structure
and not lift the cutting. Drilling muds need a yield point of:
10 - 15 to drill
15 - 20 to washover
30+ to mill
A rule of thumb for yield point during drilling operations is that yield
point should match the mud weight.

Water Loss - This is very important if wash-pipe is going to be placed in open hole.
In hard rock formations a water loss below 10 is okay. In
unconsolidated sands as in Gulf Coast offshore, the water loss needs to
be below 5. Before placing wash pipe in the hole, lower the water loss
below what it was when the drilling assembly became stuck. If you
were drilling with a 5 water loss and got stuck, lower it to a 3 before
running wash pipe.

 Cardinal Rules of Fishing

1. Know your dimensions:

A. O.D., I.D. length of the fish
B. O.D., I.D. length of the fishing tool assembly
C. O.D., I.D. length of the work string
D. MOST IMPORTANT - Know where the top of the fish is

2. Know all tensile & torsional strengths of everything you run in hole.

3. Pulling out of hole: Never rotate the fish out of the hole.

4. Trip time: Fast is not always the best.

5. Never run anything in the hole that is not O.D. fishable unless you are aware of that
fact and make an informed decision that the reward is worth the risk. For example: an
overshot is not O.D. fishable but we run them because it does not reduce the I.D. and
when run with the bumper jar, it releases 99% of the time. This is an acceptable risk.

6. Familiarize yourself with the Fish: Use composite catalog, technical manuals,
manufacturer’s drawings to learn the critical points (depth to top of slips, packer element
and bottom slips) of removing, burning over or milling up a fish. If an exact copy of the
fish, same type packer or stabilizer, etc., can be brought to the well site, it is much more
valuable than a drawing or dimensional data.

 Field Use Formulas

Manual Stretch - The overpull necessary to induce 3 ½” stretch per 1000 ft free pipe is:
2208.5x Nominal Weight of the tube in lbs./ft.

Hydraulic Force - D² x .7854 x pressure

Hydrostatic Pressure - .052 x weight x depth

Max Pull on Pipe - O.D. 2 x .7854 = A

I.D. 2 x .7854 = B A-B=C C = Net Wall Area

Net Wall Area x Minimum PSI Yield = Max Pull on Pipe (J - 55 = 55,000)
(N - 80 = 80,000)

Hole Capacity - D² (In) ÷ 1029.4 = Bbls/Ft

Displacement - Steel Weights 65.63 Pound per Gallon

String Weight ÷ 65.63 = Gallons Displacement
Divide Gallons Displacement by 42 = Bbls/Displacement

Tank Volume - L(ft) x W(ft) x H(ft) = Volume (bbls/ft)

 Four Elements of Effective Jarring Operation

In any jarring operation, make sure you have met each of the four elements or you
are not effectively jarring on the fish or stuck point. This addresses the up-jar only.

1. Restricted Pull:
A. Stuck Situation
B. Restricted Pull Device i.e. Oil Jar

2. Multiplier: Drill Collars

If you do not run drill collars or Heviwate the multiplier is less than 1.

3. Transition Area:
A. Change in mass from drill collars to tubing or drill pipe also can be the transition
area.
B. Jar Accelerator/Intensifier is the perfect transition area.

4. Stored Energy:
A. Jar Accelerator/Intensifier
B. Jarring work-string

 Stuck Pipe Conditions
“Identify the Problem”

When pipe is stuck it is critical to correctly identify the problem

-- Why is the pipe or B.H.A. stuck? Various types of sticking conditions are listed in
the following discussion.

DIFFERENTIAL STICKING - This problem occurs world-wide. The B.H.A or drill-

string becomes stuck due to the differential pressure across a zone. The B.H.A. or
drill-string is held in place against the bore hole by the hydraulic force of the
hydrostatic weight of the drilling fluid.

The most common cause of differential sticking is thick filter cake across a permeable zone.

Preventive Action:
1) Reduce wall contact w/ B.H.A. by using spiral drill collars and H.W.D.P.
2) Keep string moving. Consider rotating drill-string while standing back pipe or
picking up a stand or making a connection.
3) Maintain minimum mud weight.
4) Daily short wiper trips.

Indication of Differential Sticking:

1) Typically occurs when pipe is not moving - especially while making a connection.
2) Drill-string cannot be moved up, down or rotated.
3) Circulation is not affected in any way.

Recommended Procedure:
1) Apply torque and jar down if drilling jars are in hole and working. If jars are not in
hole or not working, apply torque and stack drill-string out. When not in jarring
mode, apply torque and stack drill-string out.
2) Spot a pipe releasing pill. Time is very critical. If the spotting agent is in place in
two hours or less, the chance of it working is enhanced. Local knowledge is very
important. What spotting agents work in your area and what is average time of release?
3) Jarring option by itself is rarely successful because the hydraulic force holding the drill-
string is commonly well over 1,000,000 pounds differential force.
4) Wash-over Operation - Be very cautious. Use a short wash-pipe string. Go for
maximum clearance between the bore-hole and wash-pipe O.D. Shoe design
should cut maximum clearance for the wash-pipe O.D. Be very cautious when
running a drill-collar spear, wash-over back-off connector, or internal screw-in
assembly in combination with wash-pipe for washing over differential stuck pipe.
Keep the wash-pipe moving.

KEYSEAT STICKING - A key seat occurs when drill pipe in tension wears a slot (keyseat) in
the wall of a hole during drilling operations. This occurs when a well deviates from true
vertical; controlled or otherwise.

Preventive Action:
When it becomes evident that a keyseat is forming, wipe it out with a keyseat wiper or string
reamer before it sticks your drill-string.

Indication of Keyseat Sticking:

1) Pipe was moving up when stuck.
2) Pipe is stuck at an O.D. enlargement in the drill-string. Typically the drill-string will be
stuck at the top of the drill-collars.
3) Circulation is not affected in any way.
4) Pipe may be able to be rotated but not reciprocated.

Recommended Procedure:
1) Surface Jars - Do not hit down with surface jars at a setting higher than the weight of
available free pipe or you are jarring up not down.
2) Back-off - Leave a minimum of two joints of free pipe above the stuck point to insure that
the top of the fish will be above the top of the keyseat.
3) Jarring Option - Screw-in with jarring assembly with enough drill collars to effectively jar
down.
4) Wash-over Option - Typically a very short interval to wash-over. Good candidate for drill
collar spear to prevent fish from dropping to bottom when washed-over.

SLOUGHING HOLE - Usually occurs immediately below a cavity. The most common cause
is very poor filter cake, across an unstable zone. A warning sign during drilling is hole fill
during connections or trips. Indication of sloughing hole sticking is pipe is stuck and hole is
packed-off. Circulation is greatly reduced or impossible.

Recommended Procedure:
1) If circulation although at a reduced rate is possible; Jarring is an option that has merit. If
the hole is packed-off, the success rate of jarring is greatly diminished.
2) Wash-over is the option that will work. Dimensions of B.H.A. and well-bore and mud
properties will dictate the risk factor in this option.

BLOW-OUT STICKING - The name clearly describes the situation. What usually occurs in a
Blow-out Sticking situation is bridging and more than one stuck interval. A free-point tool will
only located the top of the stuck drill-string. A pipe recovery log and a noise/temperature
survey are usually required to gather enough information to determine the fishing procedure.

LOST CIRCULATION STICKING - Occurs after loosing circulation. Recommended

procedure is the same as for Sloughing Hole Sticking.

CEMENTED STICKING - When pipe is cemented in place, Jarring is not an option
except on a very short section (10’ or less).

Recommended Procedure:
Wash-over can be a problem unless the pipe is centralized in the hole. If it is not
centralized, selecting a very aggressive mill and milling up pipe and cement may be the
best option. If drill collars are cemented in, of course wash-over is the best option.

UNDERGAUGE HOLE STICKING - Identify if the under-gauge hole is above or

below the bit. If a full-gauge bit is stuck in under-gauge hole while tripping in; jarring
force with an upward jar is usually successful. If the undergauge hole occurs above the
B.H.A. due to a plastic shale or salt section the recommended procedure is the same as
Sloughing Hole Sticking.

MECHANICAL STICKING - Occurs due to foreign object or junk in the hole or

crooked/cork-screwed pipe. Circulation is usually not affected.

Recommended Procedure:
Free-point and part pipe at appropriate place. Run attachment tool with jarring assembly
that will enable you to effectively jar both up and down.

SAND STUCK or MUD STUCK - The recommended procedure is the same as

Sloughing Hole Sticking. The greatest risk is that during pipe recovery a pocket will be
formed in the sand or mud that will cause the free-point tool to show free-pipe, but the
pipe cannot be pulled. Take the free-point reading at a higher pull value than when the
pipe was being reciprocated to prevent this from happening.

SELECTING FISHING OPTION - In the event of mechanical failure

(twist-off, wash-out, etc.) run appropriate fishing tool (usually an overshot with jarring
assembly) A.S.A.P.

In all other cases; identify the problem before taking action. If it is a mud/hole problem,
fix it before fishing tools are also stuck in the hole.

The decision whether to jar or wash-over can be made easier by answering the question
about circulation. Jarring is rarely successful if the hole cannot be circulated. A
formation can be mechanically squeezed by attempting to jar or pull a drill-string
through a tight place if the hole cannot be circulated while jarring or pulling.

JARRING OPERATIONS:
If the fish got stuck coming up - JAR DOWN

If the fish got stuck going down - JAR UP

Be prepared to effectively jar up and jar down with any jarring assembly run in the hole.

 Notes

Weatherford Fishing Tool Manual 21

January, 2003
 General Operational Comments on Fishing Tools

1. Overshot: First choice tool because it does not reduce I.D. and has a better pack-off
than a spear.

2. Spear: Greatly reduces I.D. and has a poor pack-off.

3. Bumper Jar: Aids in getting over or in the fish, is part of the release mechanism for
an overshot or spear and of course allows us to Jar down.

4. Oil Jars: Provides restricted pull that enables the work string or jar intensifier to store
energy and releases upward.

5. Drill Collars: Too many or too few adversely affects jarring operations. Drill Collars are
the multiplier in the impact calculation. Drill Collars can also be a transition area.

6. Jar Accelerator / Intensifier: Jar accelerator negates the affect of pipe and side wall
friction above the jar and as a result a more efficient jar impact is achieved. Jar
accelerator also protects the work string and derrick from jarring damage. Jar accelerator
stores energy and is the perfect transition area.

7. Jarring Operations: How long to Jar? Usually a maximum of 4-5 hours without any
progress of moving the fish up or down. Pay careful attention to what was going on when
you got stuck. If the fish got stuck coming up, most likely it will be freed by jarring down.
Conversely, if the fish got stuck going down, most likely it will be freed by jarring up.

8. Wash-Over Shoes: open hole, rough O.D.; cased hole, smooth O.D. Shoe material must
be AISI4100 or ASI1018 Series material not a cut-off piece of wash pipe. Length of shoe
should be fishable with a spear. Shoe design will change relative to the material to be
washed or cut over. A packer shoe will be flat bottom or ocean wave. A tooth type or
scalloped shoe would be useful for sand or dehydrated mud.

Weatherford Fishing Tool Manual 22

January, 2003
9. Wash Pipe: Must be N-80, L-80, or 1018 material. Clearance between O.D. of wash
pipe and I.D. of hole is of greater importance than the clearance between O.D. of fish
and I.D. of wash pipe. Evenly split O.D./I.D. clearance if possible. Proper annular
velocity is critical for proper hole cleaning (150’ per minute in clear fluids). Length of
wash over string - do not washover more than you can cut and retrieve. Run jars and
drill collars with wash pipe.

10. R.P.M. for Mills & Shoes: 1500 linear inches per minute is the optimum rate for any
carbide milling tool. The formula to calculate optimum RPM is as follows: 1500 ÷
3.1416 ÷ O.D. of mill or shoe. Based on this formula the recommended RPM for a 6”
O.D. mill or shoe would be: 1500 ÷ 3.1416 = 477 ÷ 6 = 80RPM.

11. Weight on Shoe or Mill: NEVER SPUD ON A SHOE! Although it will take 4-6
points of weight to overcome hydraulic lift, the actual weight on a shoe should be a few
hundred pounds. All carbide products have a given feed rate, any additional weight will
not increase the rate, but it will shorten the life of the carbide . The proper way to mill
is by torque not weight. Maintain a constant minimum weight that will maintain the
torque at the carbide contact area. Circulation for cooling of carbide is critical,
minimum rate 1/2 BPM.

12. Mills: Four most important characteristics in prioritized order:

1) durability
2) repeatability
3) types of cuttings and amount
4) speed

MILL DESIGNS:
Concave: Concave design centers mill over fish and is less likely to sidetrack.

Roundnose: Usually run on second mill run cutting a window with whipstock. Very
seldom run on anything else.

Weatherford Fishing Tool Manual 23

January, 2003
 Watermelon / String Mills: Run with window mill will increase window height in
whipstock. They can be run with a drill collar above and below to mill out tight spot in
casing. The drill collars greatly reduce the side track potential.

Pirahna Mill: Mills with a throat rather than small water courses.
A very aggressive mill.

Bladed Junk Mill: Concave design and faster cutting rate through sand, cement or
fill.

Tapered Mill: Originally designed to dress a line top and probably should not be
used for anything else due to side - track potential. Tapered mills are run in some
whipstock applications.

13. If tubulars are not fishable on the outside due to sand, mud, collapsed casing or size,
consider making all necessary cuts with electric line early on before I.D. becomes
plugged by wash over operation. If fish can pass in a hole, stair-step or mix the length
of cut. (larger casing is good candidate for wash down outside cutter.)

14. Circulation: Pre-planning the type of fluid to be used to remove the cutting and debris
from the well is very important. Also, any burning, milling or washing over will require
some type of fluid to perform the hydraulic functions needed for each of these methods.
When performing washover operations the two greatest hydraulic frictional losses occur
in 1) the internal diameter of the work string and 2) the annular space between the I.D.
of the casing and the O.D. of the wash pipe. Pressure drop calculations and the relative
annular velocities to remove solids from the well should be made to determine if the
work string needs to have a larger I.D. or the wash pipe needs to be smaller O.D. This
is very important in deep wells (10,000’ or deeper) with high density (15 PPG and
heavier) whole mud as the workover fluid.

 Pipe Recovery Log
Pipe Recovery Log
The McCullough Pipe Recovery Log utilizes
a sonic system which sets up a vibration in
the stuck pipe. This vibration, measured by
a receiver, decreases at stuck intervals in
proportion to the severity of the stuck
condition. It is an acoustical type survey
consisting of a transmitter and receiver in a
sonic section. The transmitter emits rapid
pulses which travel through the pipe to the
receiver. The entire logging system, both
downhole tools and surface instruments,
utilizes solid state electronics to insure
trouble-free performance.

The 1-3/4" O.D. down hole instrument is

run on a single-conductor electric cable.
The logging instrument is calibrated in
known free pipe—normally near the bottom
of the surface pipe or last casing string.
After recording, a signal attenuation scale is
placed on the log. This scale, expressed in
percentages, accurately indicates the
severity of stuck conditions at each interval.

Thus, the Pipe Recovery Log gives a

complete record of all stuck intervals and
possible trouble areas in a string of stuck
pipe. It gives the length of each stuck
interval. It records the severity of stuck
conditions at each interval. And it indicates
how much each interval contributes to the
total stuck condition of the pipe.

While the McCullough Pipe Recovery

Log has had its greatest use in stuck drill
pipe and drill collars, it also has been
successfully used to evaluate the stuck
condition of washpipe, casing, tubing and
liners.

In stuck tubing, the Pipe Recovery Log

will indicate if it is stuck at the packer, if the
tubing is sanded-up, the severity of the
stuck conditions, and if the bridges have
formed in the annulus between tubing and
casing.

In stuck wash-pipe, casing or liners the

Pipe Recovery Log will indicate the most
practical and economical method of
recovery.

Pipe Recovery Log with Gamma Ray Log in Conjunction
Gamma Ray Collar Log Pipe Recovery Log
While the Pipe Recovery Log may
be run individually, it is
recommended that it also be run in
conjunction with a Gamma Ray
Log if no log of the well is
available.

The Gamma Ray Log shows

what type of formation is causing
the stuck condition. This
information is of great value in
determining the most practical and
economical procedure for
recovering the stuck pipe.

A collar Log is always recorded

simultaneously with a Pipe
Recovery and Gamma Ray Log.

 Differential Temperature Log
Temperature in the well bore
Differential Temperature Log Differential Temperature Log increases with depth. The
geothermal gradient, or rate of
increase, is approximately 1°F per
60 feet on the average. However,
the geographic location and the
heat conductivity of the geological
formation can cause the
temperature change to deviate from
the average. In a well where the
fluid is circulating, the fluid will tend
to have a uniform temperature. If
the well is allowed to stand without
circulation, the fluid will reach the
temperature of the formation around
it. In other words, it would be more
dependent on the natural
geothermal gradient.

Most temperature surveys are

made during the transition period
before the fluid has enough time to
reach thermal equilibrium with the
adjacent formations. If another run
is to be made in the well, there
should be a period of several hours
allotted so that stabilized
temperature conditions may be re-
established.

In the case of lost circulation, it is

known that fluid taken by the
formation is continually being
replaced by fluid pumped into the
well. In running the temperature

 BOWEN SERIES 150
RELEASING & CIRCULATING OVERSHOT
(PATENTED)

The BOWEN OVERSHOT has gained world-

wide acceptance for fishing by means of external
engagement of a fish. Each BOWEN
OVERSHOT is a carefully engineered unit. In
service, it takes a positive grip over a large area of
fish and is therefore capable of withstanding
extremely heavy pulling, torsional and jarring
strains without damage or distortion to either the
tool or the fish.

GENERAL DESCRIPTION

The BOWEN SERIES 150 RELEASING AND

CIRCULATING OVERSHOT provides the
strongest tool available to externally engage, pack
off and pull a fish. The basic simplicity and rugged
construction with which it is designed have made it
the standard of all external catch fishing tools.

During the releasing operation, a sharp
downward bump places the larger portion of the Bowl

breaking the hold. Thereafter, when the Overshot is
rotated to the right, and slowly elevated, the wickers
will screw the Grapple off the fish, effecting release.
The fact that Bowen Releasing and Circulating
Overshots require right hand rotation only, both
during engaging and releasing operation, is
extremely important. This feature eliminates the
dangers that are present when it is necessary to rotate
the string to the left.
All Mill Control Packers are manufactured to pack off a

Calculated Strengths
Note: All strengths listed are calculated theoretical yield points and are accurate within 20%. It should be noted,
however, that all strengths assume a straight, steady pull and full grapple engagement of a round fish. Anything
less than full engagement or straight pulling will reduce the strength substantially. This includes tong marks or
other damage to the bowl surface.
*Type Explanation
FS Full Strength-Engineered to withstand all pulling, torsional and jarring strain.
XFS Extra Full Strength-Engineered for extreme abuse.
SFS Semi Full Strength-Engineered for special hole condition commensurate with maximum strength.
SH Slim Hole-Engineered to withstand heavy pulling strains only.
XSH Extra Slim Hole-Engineered for pick up jobs only.

Calculated Strengths
Note: All strengths listed are calculated theoretical yield points and are accurate within 20%. It should be noted,
however, that all strengths assume a straight, steady pull and full grapple engagement of a round fish. Anything
less than full engagement or straight pulling will reduce the strength substantially. This includes tong marks or
other damage to the bowl surface.

 BOWEN SUCKER ROD OVERSHOTS
SERIES 10 & SERIES 20
(PATENTED)

GENERAL DESCRIPTION

BOWEN SUCKER ROD OVERSHOTS are

sturdy, compact units designed to engage sucker rods
or other items used inside of tubing. Designed and
developed upon the same principle as other BOWEN
OVERSHOTS, they are the most effective means for
the recovery of sucker rods.

USES

BOWEN SERIES 10 OVERSHOTS are designed

to recover non-hardened Sucker Rod Boxes up to 2"
O.D. inside of 2-7/8" tubing and up to 1-5/8,' O.D.
inside of 2-3/8,' tubing. Basket Grapples are
recommended for fishing for hardened and ground
boxes.

BOWEN SERIES 20 OVERSHOTS are

shortcatch sucker rod overshots, which provide a
means for engaging the exposed portion of a fish too
short to be engaged with conventional catch overshot.

BOWEN SUCKER ROD OVERSHOTS, fitted

with tubing thread Top Subs and Oversize Guides, are
ideally suited for engaging the fishing neck of wire
line rope sockets and retrieving wire line tools such as
gun perforators lost inside of casing.

BOWEN SERIES 10 & 20 OVERSHOTS will

effectively catch fish as much as 1/64” maximum
undersize and 1/64” maximum oversize.

CONSTRUCTION

A BOWEN SUCKER ROD OVERSHOT —

SERIES 10 consists of a Top Sub, a Bowl, a Spiral
Grapple and a Control Guide. When a Basket Grapple
is used in a Series 10 assembly, a Basket Grapple
Control and a Plain Guide are required.

A BOWEN SUCKER ROD OVERSHOT —

SERIES 20 consists of a Top Sub, a Bowl, a Grapple
Control and a Basket Grapple. It differs from a Series
10 in that the Grapple Control is at the top of the
Bowl above the Basket Grapple placing the Grapple at
the lowermost position in the Bowl.

OPERATION

First determine that the Overshot is properly

assembled, is dressed with the proper size Grapple
and that all of its parts are in good working order.
Refer to the Specification Table for list of parts.

 MAINTENANCE

Maintenance of Bowen Sucker Rod Overshots is simple,

but important. After each use, the tool should be
disassembled, inspected, repaired as required and re-
assembled.

DISASSEMBLY

1. Clamp the Bowl in a vise between the threaded ends.

Break loose the threaded connections of the Top Sub and
Guide; remove the Top Sub and Guide. Caution: Use only
sufficient gripping action in the vise to break connections;
excessive force can distort or crack the Bowl. Also, avoid
leaving heavy tool marks on the Bowl, which reduce the
longevity of the Bowl.

2. Remove the Grapple. This may be done by unscrewing it

from the Bowl, using right-hand rotation.Where the Grapple
is a Basket type, the Control must first be lifted out; through
the bottom in the Series 10 Assembly, and through the top
in the Series 20.

Inspect all the parts before reassembling them;

particularly the Grapple. Check the wickers to assure that
they have not been damaged or worn too much for
additional safe operation. Grease the parts as they are re-
assembled. To prevent rust or deterioration, either grease or
paint the exterior.

BOWEN SHORT CATCH OVERSHOTS
(PATENTED)

SERIES 70 BOWEN SHORT CATCH

OVERSHOTS are especially designed to engage
the exposed portion of a fish too short to be
engaged with conventional catch overshots.
Designed and developed upon the same principle
as other BOWEN OVERSHOTS, they are the
most effective means for the recovery of a fish
whose exposed upper end is very short.

USE
Each SERIES 70 BOWEN SHORT CATCH
OVERSHOT is designed to engage a specific
maximum outside diameter. (See the Table of
Specifications). Each Overshot can be dressed to
engage any smaller diameter by installing the
desired size of Basket Grapple.

CONSTRUCTION
A SERIES 70 BOWEN SHORT CATCH
OVERSHOT consists of a Top Sub, a Bowl, a
Basket Grapple Control and a Basket Grapple. In
this Overshot, the Basket Grapple is inserted into
the Bowl from the top and the finger of the Basket
Grapple Control fits into the top of the Basket
Grapple. The Bowl is designed to allow the Basket
Grapple to be located at its extreme lower end.

OPERATION
First determine that the Overshot is properly
assembled, is dressed with the proper size Grapple
and that all of its parts are in good working order.
Refer to the Specification Table for list of parts.

Make up the Overshot on the fishing string and

run into the well.

To Engage and Pull the Fish

As the top of the fish is reached, slowly rotate
the fishing string to the right and gradually lower
the Overshot over the fish; combined rotating and
lowering is important.
Allow the right-hand torque to slack out of the
fishing string and then pull on the fish by elevating
the fishing string.

To Release from the Fish

Bump down; then simultaneously rotate to the
right and slowly elevate the fishing string until the
Overshot is clear of the fish; combined rotating
arid elevating is important.

 Table of Calculated Strengths
for
Bowen Short Catch Overshots
Series “70”
“Note: All strengths listed are calculated theoretical yield points and accurate within 20%. It should be noted, however, that all
strengths assume a straight, steady pull and full grapple engagement of a round fish. Anything less that full engagement or straight
pulling will reduce the listed strength substantially. Tong marks and other surface damage to the bowl will also reduce the strength.
Jarring may amplify the pull load by a factor of 3 to 10.”

 Itco Type Bowen Releasing Spears (Fig. 13)
provide a dependable, inexpensive and simple
means of engaging a fish internally. These Spears
insure positive engagement, easy release from the
fish when desired, and easy re-engagement after
the Spear has been released. Mandrel Mandrel

Essentially, the tools consists of a Mandrel on

which is assembled a Grapple, Release Ring and
Nut. After the Spear has been lowered into the
fish, rotate the string one full turn to the left. This
Grapple
turns the Mandrel of the Spear down through the Grap
Grapple, placing the Grapple in an engaging position.
A straight pull will then wedge the Grapple into
positive engagement with the fish. To release,
bump down to break the hold, then rotate two or Release Ring Release Ring
three turns to the right. This moves the Mandrel
up through the Grapple, forcing the Grapple against
the Release Ring and putting the spear in its release Nut Nut
position. A straight upward pull will then generally
free the Spear. However, it is recommended that the
string be rotated slowly to the right as the Spear is
lifted out of the fish. The matching cams of the Itco Type Bowen Itco Type Bowen
Releasing Spear Releasing Spear
Release Ring and Nut constitute a safety device which with Bull Nose Nut with Sub Type Nut
resists freezing or jamming. (Shoulder Mandrel (Flush Mandrel in
in Engaged Position) Releasing Position)
The tool is available in two types -- one known as the
Flush Type and the other as the Shoulder Type. A Fig. 13
Flush Type Spear can be supplied when the specified upper connection can be cut in the standard outside
diameter of the Mandrel. If a larger connection is
required, a Shoulder Type Spear will have to be purchased.
Sometimes it is desirable to have more length than standard
immediately below the shoulder. In order to supply a Spear to
meet the requirements, it is necessary for the purchaser to
specify the exact increase in length that he desires.

SEGMENT TYPE SPEAR GRAPPLE

Retainer Screw
Grapple
The Bowen Segment Type Spear Grapple is used to extend Retainer Ring
the catching ability beyond the range of a one piece Segment Screw
grapple(see chart below). This grapple consists of a Grapple
Body, eight Grapple Segments, two Retainer Rings, six Ring Grapple Segment
Screws, six Ring Spacers, and Grapple Segment Screws.
The helix of the Grapple Body matches that of the Spear
Mandrel, thereby making the action of the Spear the same as
Grapple Body
with a Standard Grapple.

Bowen Full Circle Releasing Spears offer many
outstanding advantages for all fishing jobs where it
is necessary to engage a fish internally. Secure
engagement is assured by the Full Circle Slips
which present up to 450% more useful area for
engagement with the fish than any other spear on
the market today.
Positive Release is assured by the primary release
mechanism, backed by the left-handed wickers on
the Slips which allow the tool to be unscrewed
from the fish, using right-hand rotation.
These tools are versatile, a size being available for
each tubing, drill pipe and casing size. The full
complement of accessories available include Mill
Type, Sub Type and Sidehill Type Nuts,
Extensions, Safety Ring Packoffs and Skirts and
Guides. Generous bores are provided through the
tools to assure ample fluid flow to help remove
settings and furnish lifting force to the fish.

Note:
“All listed strengths are theoretical calculations based upon the yield strength of the material and are accurate within
20%. They refer to the tensile strength of the body and do not relate to the strength of the fish being engaged. Thin
walled or old corroded pipe may allow the grapple to expand to the point where it can “jump” the mandrel spirals.

Jarring may amplify the pull load by a factor of 3 to 10.”

 WARNING
All jarring and pulling loads shown in this manual assume that the force is acting alone and is essentially along
the major axis of the tool. If torque and tension or bending and tension are used together, the resulting combined
stresses may lead to failure at substantially less than rated loads. Rotation and bending together can lead to fatigue.

*Based on 80% of Calculated Load at Yield Point.

**Optimum weights can be determined only by calculation and only if sufficient well data is available

THESE FIGURES DO NOT CONSTITUTE A GUARANTEE, ACTUAL OR IMPLIED; THEY ARE MEANT TO SERVE AS
A GUIDE ONLY, AND APPROPRIATE ALLOWANCE MUST BE MADE IN USE, AS A SAFETY FACTOR.

Users of jars and bumper subs should be aware that milling or drilling operations may develop stresses in these tools that are
more complex than the simple torsional and tensile values listed in Bowen strength data. If unstabilized, the weight necessary
for milling can induce bending forces that combine with torsional forces to generate very high stresses in some areas of the
tool. Rotating in a deviated hole condition or with the tool in a neutral point may have the same effect.

The necessity for milling is recognized and this is not intended to advise against such operations, but merely to caution the
user of possible dangers when rotating under the conditions described.

 BOWEN FISHING MAGNETS
Bowen Fishing Magnets are used to retrieve all types of
small objects having magnetic attraction from bore hole
bottoms. Such undrillable objects as bit cones, bearings,
slips, tongs pins and milling cuttings can often be retrieved
only by magnetic attraction.

These Fishing Magnets are particularly valuable for use

prior to diamond coring. In a single trip, the Bowen
Fishing Magnet will completely clean the hole of these
damaging junk items, insuring good performance and
safeguarding the valuable bit. Wire Line
Adapter
Bowen Fishing Magnets may be run on wire lines or on
pipe. Wire line operations have the advantages of speed
and economy. Pipe operations has the great advantage of
utilizing the generous circulation holes in the magnet to
eliminate settlings above the fish, and to loosen the fish.
The first six assemblies (with sucker rod connection), do
not have circulation bores.

Bowen has Wire Line Adapters available to run between

the Magnet and cable head or rope socket. When ordering, Lipped Guide
specify the required top connection and the Magnet to be
used with.

Cut-Lipped, Flush O.D. Type and Mill Type Guides are Flat
available as optional accessories. Order by standard Guide Bottom Mill Guide
number, specifying type required and Magnet to be used Guide
on.
The Bowen Magnet Charger is designed to induce a
strong magnetic charge into bar type fishing magnets. It is
able to do big charging jobs with small electrical service.
The Bowen Magnet Charger is a pulsed type unit and
requires much less electrical power than ordinary
continuous type chargers.

The Bowen Magnet Charger includes a Power Supply Unit

and Magnetizing Coil Unit. The solid state Power Supply
Unit converts Alternating Current input into short pulse,
high-peak Direct Current output to the Magnetizing Coil.

The magnet is placed in the Magnetizing Coil and locked

into place by means of adjustable arms which are a part of
the magnetic circuit. A push of the button on the Power
Supply Unit starts the magnetizing cycle, which
automatically shuts off after the short interval of time
required to reach peak magnetizing force.

The Bowen Magnet Charger can be used to magnetize

Size 14" 20" fishing magnets up to 14 and 20 inches outside diameter.

 ITCO TYPE
BOWEN JUNK BASKETS
(PATENTED)
GENERAL DESCRIPTION
The BOWEN JUNK BASKET — ITCO TYPE is
an uncomplicated yet dependable fishing tool for
retrieving all kinds of loose junk. Its simplicity of
design, construction, operation and maintenance is
such that any drilling crew can use it successfully.
With free revolving double catchers, magnet inserts
and accessory shoes, the BOWEN JUNK BASKET is
indispensable equipment on a rotary drilling rig.

USE
The BOWEN JUNK BASKET is used to retrieve
all sorts of junk that may accumulate at the bottom of
a well and which may impede drilling progress. This
junk may be such objects as rock bit cones, bearings,
broken slips, bits of wire line, various hand tools,
slivers and debris from twisted off drill string, milling
cuttings, etc. It may also be used to take a core
sample, drill a full gauge hole or to ream the hole.

CONSTRUCTION
The BOWEN JUNK BASKET - ITCO TYPE
consists basically of a Barrel, a Top Sub, an Upper
Catcher, a Lower Catcher, and a Type "A" Mill Shoe.
This type shoe is faced with conventional hard metal
on the cutting surfaces. Accessories include Magnet
Inserts, Mill Shoes dressed with Itcoloy and Finger
Shoes. The two catchers employ rivet-free
construction, easily redressed on location. Catcher
Fingers are cast from strong, long wearing manganese
bronze. The Fingers in the Upper Catcher extend only
half way to the center, its function being to break the
core when an upward strain is taken on the string. The
Lower Catcher has alternately long and short fingers
which extend almost to the center, forming a close
fitting basket which will retain the core or small
pieces of junk. Both Catchers are free to revolve
within the Shoe, eliminating Finger breakage.

 BOWEN
REVERSE CIRCULATION
JUNK BASKETS
PATENTED

GENERAL DESCRIPTION
The BOWEN REVERSE CIRCULATION
JUNK BASKETS are designed to effectively catch
junk by utilizing the reverse circulation principle.
Small junk objects may be successfully deflected
into this Junk Basket and retrieved, which would not
be fished out by other junk baskets.

The tool's unique reverse circulation feature insures

very complete recovery of junk, and eliminates
misruns. Its design also retains a drain through the
tool that eliminates the possibility of pulling a wet
string even though the inner barrel is plugged by the
core. This tool may also be converted into an
effective Fishing Magnet which still retains the
reverse circulation feature.

USE
The BOWEN REVERSE CIRCULATION
JUNK BASKETS are used to retrieve all types of
junk that accumulates at the bottom of a well. This
junk may be such objects as rock bit cones and
bearings, broken slips, bits of wire line, various
hand tools, slivers and debris from twisted-off drill
strings, milling cuttings, etc.

In operation the circulating fluid is jetted outwardly

and downwardly against the full circumference of
the hole, where it is deflected in a manner that
directs all objects into the long hollow barrel of the
basket.

CONSTRUCTION
The BOWEN REVERSE CIRCULATION
JUNK BASKETS consist basically of a Barrel, a
Top Sub, a Junk Catcher, a Shoe, and a Valve
Assembly. A Lifting Sub is provided for ease of
handling the Junk Basket and provides a storage
place for the Steel Ball.

 BOWEN
FULL FLOW TYPE
REVERSE CIRCULATION
JUNK BASKETS
[PATENTED]

GENERAL DESCRIPTION
The BOWEN FULL FLOW TYPE REVERSE
CIRCULATION JUNK BASKETS are designed to
effectively catch junk by utilizing the reverse
circulation principle. Small junk objects may be
successfully deflected into this Junk Basket and
retrieved, which would not be fished out by other
junk baskets.

The tool's unique reverse circulation feature

insures very complete recovery of junk, and
eliminates misruns. Its design also retains a drain
through the tool that eliminates the possibility of
pulling a wet string even though the inner barrel is
plugged by the core. This tool may also be converted
into an effective Fishing Magnet which still retains
the reverse circulation feature.

USE
The BOWEN FULL FLOW TYPE REVERSE
CIRCULATION JUNK BASKETS are used to
retrieve all types of junk that accumulates at the
bottom of a well. This junk may be such objects as
rock bit cones and bearings, broken slips, bits of
wire line, various hand tools, slivers and debris from
twisted-off drill strings, milling cuttings, etc.

In operation the circulating fluid is jetted

outwardly and downwardly against the full
circumference of the hole, where it is deflected in a
manner that directs all objects into the long hollow
barrel of the basket.

CONSTRUCTION
BOWEN FULL FLOW TYPE REVERSE
CIRCULATION JUNK BASKETS consist basically
of a Barrel, a Top Sub, Junk Catcher(s), a Shoe, a
Filter, a Valve Assembly and a Pick Up Sub. The
Valve Assembly consists of a Ball, a Ball Seat, a
Ball Seat Retainer, four Shear Pins, and Seals.

Weatherford Fishing Tool Manual 105

January 2003
 These Junk Baskets are available with one ( 1) Junk
Catcher Assembly or they can be provided with two (2)
on request.

EXPLANATION OF MECHANISM
The BOWEN FULL FLOW TYPE REVERSE
CIRCULATION JUNK BASKETS are designed to
retrieve all types of small objects such as bit cones, tong
pins, hammers, mill cuttings, and similar junk. Its
unique principle of reverse fluid circulation insures
more complete recovery of junk in the hole and
eliminates misruns.

Full Flow Type Valve Assembly

The Full Flow Type reverse circulation is obtained
the same way as the Standard Type. The unique feature
of the Full Flow Type is in the Valve Assembly.
Sometimes when the Standard Type is being lowered
into the well toward a fish, pieces of shale, shell, etc.,
break away from the walls, sift up through the catchers,
and clog the valve which starts the reverse flow action
prematurely when it is not desirable. The Full Flow is
designed to seal off the cavity used in the reverse
circulation until it is needed. When dressed for running
in the hole, the Ball Seat of the Full Flow type is
fastened to the Ball Seat Retainer with Shear Pins. This
blocks off the reverse circulation ports and provides a
"washpipe" between the Top Sub and Barrel so that flow
will be directed through the I.D. to keep the Barrel
washed clean while going in the hole. When the Basket
is over the fish, the ball is dropped and seated, pump
pressure causes the pins to shear, the Ball Seat drops
down to a matching beveled shoulder of the Valve
Assembly part of the barrel which opens the cavity, and
reverse circulation starts. (See illustration)

ACCESSORIES

Mill Shoes
The BOWEN FULL FLOW TYPE CIRCULATION
JUNK BASKETS are furnished with a standard Type
"A" Mill Shoe. This is a mill type with side wings. It is
recommended that Itcoloyfaced Mill Shoes be
considered.

The Type "B" Mill Shoe is similar in design to the

Type "A" but is hard-faced with BOWEN ITCOLOY.
ITCOLOY is a material composed of sintered tungsten
carbide in an extremely tough matrix which will
effectively and rapidly mill up junk during the fishing
operation.

 BOWEN INTERNAL CUTTER
(PATENTED)

GENERAL DESCRIPTION
BOWEN INTERNAL CUTTERS are ruggedly
built, efficient tools for cutting tubing, casing or drill
pipe. Sizes ranging from 1.900" tubing up to 20-3/4"
casing are available. BOWEN INTERNAL
CUTTERS are manufactured to exacting standards
of interchangeability, permitting relative ease of
maintenance after use and the redressing of a basic
assembly to cut alternate sizes of pipe. (See
Specification table for sizes, part numbers and "can
be dressed to cut" sizes)

USE
The BOWEN INTERNAL CUTTER is used to
cut tubing, casing or drill pipe. It may be run on
"macaroni" tubing, tubing or drill pipe, depending
upon the diameter of the pipe to be cut.

CONSTRUCTION
The BOWEN INTERNAL CUTTER consists
essentially of a Wiper Block (or a Drag Spring
Assembly) to accomplish setting in the pipe, Slips
and Cone Assembly to anchor the tool, a Main
Spring to assist in maintaining uniform feed to the
Knives, wedge-like Knife Blocks to drive the Knives
upward and outward to engage the pipe, and
especially hardened and ground Knives for easy,
efficient pipe cutting. A feature of the BOWEN
INTERNAL CUTTER is the "Automatic Bottom"
which permits the operator to set the cutter easily at
any desired depth, to release the tool by simply
pulling upward, and to reset at another depth - all
without coming out of the hole.

OPERATION
The BOWEN INTERNAL CUTTER should be
thoroughly examined to assure that it is properly
assembled, all threaded connections made up tightly
and that it is properly dressed for the size pipe to be
cut. Refer to the Reassembly Procedure and the
Specification Chart on the following pages for the
correct assembly, part numbers and dimensions.

The BOWEN INTERNAL CUTTER is made up

on the bottom of the cutting string. The cutting string
may be "macaroni" tubing or drill pipe, as the
diameter of the pipe to be cut and the circumstances
dictate.

Weatherford Fishing Tool Manual

January, 2003 113
RUNNING IN
Before lowering in the well, check the BOWEN
INTERNAL CUTTER to be sure that the Automatic
Bottom is fully engaged. This engagement holds the
cutter in a released position with the Slips and
Knives retracted while running into or out of the
well.

CAUTION:
Avoid right-hand rotation as the BOWEN
INTERNAL CUTTER is lowered into the well
because right-hand rotation will release the
Automatic Bottom and set the cutter in operating
position. If this should occur, slowly raise the cutting
string and the Wickered Sleeve will be reengaged by
the Grip Jaws to reset the cutter in running position.

CONVENTIONAL CUTTING PROCEDURE

Upon reaching the desired cutting depth, the
BOWEN INTERNAL CUTTER is anchored by
slowly rotating to the right while slowly lowering the
run-in string. The Wiper Blocks (or Drag Springs)
resist rotation and lowering by maintaining friction
on the pipe. This disengages the Automatic Bottom
from the Grip Jaws. Continued lowering or
"creeping" of the run-in string causes the Cone to
move the Slips upward and outward to anchor the
cutter in the pipe. The Mandrel is free to travel
downward under the Knife Blocks forcing the
Knives upward and outward to start the cut. Slight
additional weight is applied while slowly rotating to
the right. The Main Spring in the upper part of the
cutter is partially compressed by the applied weight
and assists in maintaining a uniform feed to the
Knives.

Cutting is accomplished by slow rotation to the

right (10 to 18 rpm) with just enough weight being
applied gradually to feed the Knives into the metal.
Care should be exercised not to try to hurry the
cutting operation as excess weight will cause the
Knives to dig into the pipe burning the Knife points.

For best operation, the run-in string is lowered in

1/16 " intervals - never more than 1/8 ''- a total
lowering of 1-1/4 " will complete the cut.

Free rotation, with little or no reverse torque,

indicates that the cut is completed. To prove the cut,
increase the rotating speed; and if no increase in
torque is noted, it will indicate that the cut has been
successfully completed.
Weatherford Fishing Tool Manual
January, 2003 114
ACCESSORY - BOWEN COLLAR FINDER
BOWEN COLLAR FINDERS are available for all sizes
of BOWEN INTERNAL CUTTERS. They enable the
operator to locate the nearest collar at the cutting depth.
With this information, the operator can then set the Cutter
above or below the located collar and thus avoid the
possibility of attempting to cut within a collar. Furthermore,
by making the cut either immediately above or below the
located Collar it is possible to salvage the pipe in more
usable lengths.

BOWEN COLLAR FINDERS assemble in the bottom of

the Bottom Nut of the Cutter. A Bottom Nut with a threaded
plug is substituted for the standard nut. The Collar Locators
are yieldably pressed outwardly by the Collar Locator
Springs at angles that permit free lowering into pipe.
However, when the assembly is elevated, the upper ends of
the Collar Locators will engage in the first encountered
space between two joints of pipe and thus locate the exact
position of the joint. After the joint is located, the Collar
Finder may be released by exerting sufficient upward pull to
break the Shear Pin. When the Shear Pin is sheared, the
Collar Locators drop into the Sleeve and are retained
therein. To prepare the Collar Finder for the next run, it is
necessary simply to replace the Shear Pin.

During the running in of the string it is necessary at

intervals to elevate the string slightly in order to remove the
rig table slips or spider slips. All BOWEN COLLAR
FINDERS are, therefore, equipped with a Spring, and this
Spring will absorb over eight inches of elevation before any
pressure is exerted directly on the Shear Pin. Thus the
possibility of snapping the Shear Pin during the running in
of the string is eliminated.

COLLAR LOCATION
At the cutting depth, elevate the cutting string slowly
until a slight but noticeable jarring reaction occurs in the
string. Mark the string at this point. The BOWEN COLLAR
FINDER is now within a located collar. From this point,
locate the Knives of the Cutter at the desired point either
above or below the located collar.

BOWEN COLLAR FINDER MAINTENANCE

To guard against failures and to prolong the life of the
tool, the Collar Finder should be thoroughly serviced after
each group of runs.

 Bowen External Tubing and Drill Pipe Cutters

Bowen External Cutters are automatic spring-fed

cutters that provide fast, efficient, external cutting and
recovery of long sections of tubing, drill pipe or
casing. The spring-fed feature prevents excessive
strain from being applied from the rig floor, which
could cause the knives to burn or break before the cut
is made.

The Body of the Bowen External Cutter is designed so

that when an upward strain is taken on the cutting
string (and the Spring Dog Assembly has engaged a
tool joint or collar), the downward travel of the Spring
Dog Assembly and the Thrust Washers is limited to
compressing the Main Spring and to shearing the Feed
Ring Shear Pin. Thereafter the Knives are fed for the
cutting operation only by the Main Spring. A Thrust
Bearing Assembly assures smooth, low-friction
rotation of the cutter.

The Spring Dog is designed to catch under the

coupling to actuate the cutter and retain the cut-off
section of the pipe. It is effective for use with
couplings, collars or squared shoulder tool joints. It is
standard and will be furnished unless an alternate
optional catcher assembly is specified.

The optional Ratchet Pawl Assembly is used if the

pipe being cut has external upset integral tool joints.
This assembly may also be used with couplings.

 Bowen Hydraulic External Cutters

Bowen Hydraulic External Cutters are hydraulically

actuated mechanical tubing and drill pipe cutters. The cutters
provide fast, efficient, smooth cutting, and are capable of
cutting and recovering strings of tubing or drill pipe. The
Cutter Knives are fed entirely by pump pressure, thus giving the
operator sensitive control.

Simple, yet rugged, Bowen Hydraulic External Cutters are

composed of a Top sub, Body, Guide, a set of knives, and a
Segmented Piston Assembly. Two Shear Pins hold the Piston
in a “running in” position until they are sheared to begin the
cut.

The Piston Assembly is composed of a Rubber Ring and set

of interlocking, conical piston segments. The segments are held
in a contracted position by a tough Rubber Ring stretched
around the end of the segments in a suitable groove. Each
piston segment has a fluid passage which is engineered to
simultaneously pass fluid for flushing, cooling, and restricting
the fluid flow for ample pumpdown force on the knives to
effect the cut.

To operate, assemble the cutter using the proper size and

type of Piston Assembly. Run the cutter into the hole to cutting
depth. When cutting depth is reached, open the fill-up and
standpipe valves just enough to shear the shear pins.

Begin slow rotation; 15 to 25 RPM. Slowly close the bypass

valve again to pump fluid down the working string. This will
begin feeding the knives to start the cut. The amount of
pressure and gallons per minute required depends on the size
cutter and piston assembly being used. Use extreme caution to
avoid surging of pump pressure when starting a cut. Pressure
surging causes the string length to contract and expand, moving
the cutter up and down. This motion prevents the knives from
remaining in one position when starting a cut.

A rough chattering action followed by the smoothing of the

rotary will signal the completion of the cut.

Bring the cut section out and strip it from the washpipe. Do
not spud coming out of the hole.

Bowen Simplex Packer Retriever
STINGER
BOWEN SIMPLEX PACKER RETRIEVER STINGERS are
simply extensions that permit the Retriever to be lowered
completely through the packer during the milling operation.

BUSHING
The Bushing is provided with a box connection at its lower end for
attaching the Stinger, also a pin connection at the lower end for
attaching a Mill Shoe and a box connection at its upper end for
connection to the run-in or fishing string. Bushings are provided
with circulation ports that may direct some fluid down around the
outside of the Retriever.

MILL SHOES
Mill Shoes for BOWEN SIMPLEX PACKER RETRIEVERS are
of sufficient length to completely mill away the slips of the packer
and contain the packer within its length. The Mill Shoe is faced
with BOWEN ITCOLOY (sintered tungsten carbide) on its leading
edge and on its internal diameter. The lower outside diameter may
be dressed with hard-facing material to reduce wear. Mill Shoes
are made with additional length to permit redressing with BOWEN
ITCOLOY several times. The Mill Shoe must be of a length which
will shroud the packer.

When more length is needed, a Short Mill Shoe may be used with a
piece of washpipe, of sufficient length, in place of the long Mill
Shoe. (See assembly illustrated here.)

OPERATION
Make up a complete BOWEN SIMPLEX PACKER RETRIEVER
ASSEMBLY consisting of Retriever, Stinger, Bushing and Mill
Shoe. Make sure to determine the following:
1. That the Retriever is the correct size for the packer to be caught.
2. That the Stinger is sufficiently long to permit the Retriever to
pass completely through the packer.
3. That the Bushing and Mill Shoe are the correct size for the
casing specifications.
Refer to the Specification Tables and Range Charts in the
following pages.
Make up complete assembly to the fishing string.

 Bowen Packer Type Casing Patches
GENERAL DESCRIPTION
The BOWEN PACKER TYPE CASING PATCH is
an external catch tool, designed to engage a previously
prepared fish, pack it off, and become a permanent part
of the repaired casing, pipe or tubing.

The same dependable method of engagement and

release which is utilized for Bowen Overshots is
employed in the BOWEN PACKER TYPE CASING
PATCH. This method assures positive engagement and
positive seal-off from either direction. The Patch
provides a permanent connection which remains rigid
and leak-proof for many years, yet is positively
releasable if ever the need arises.

BOWEN PACKER TYPE CASING PATCHES will

not restrict the bore of the casing or tubing in any
manner.

The BOWEN PACKER TYPE CASING PATCH is

composed of three outside parts and five internal parts.
This simplicity of design is matched by the simple
positive operation.

USE
The BOWEN PACKER TYPE CASING PATCH as
indicated, is used to repair a damaged casing string by
replacement of the damaged section, without having to
remove the entire string of casing from the hole.

Where the upper portion of a casing string becomes

ruptured or disoriented from the lower portion such as
by faulting or caving of the f o r m a t i o n, crushing,
rupture, or backing off, the upper portion must be
removed. New casing is then replaced, the BOWEN
PACKER TYPE CASING PATCH forming the
patching means between the old and new strings.

CONSTRUCTION
The BOWEN PACKER TYPE CASING PATCH is
constructed in the most basic manner to perform the
functions of engaging the fish, sealing off the fish, or
releasing, either during or after setting operations,
should this become advisable.

Weatherford Fishing Tool Manual

January, 2003 131
 The TOP SUB, BOWL and GUIDE form the outer
assembly.

The TOP SUB has an upper connection to match the

running string, and a lower connection to mate with the
Bowl. A Top Sub Seal is located immediately below the
lower thread of the Top Sub.

The BOWL has an upper connection for the Top Sub, an

area of length into which the PACKER PROTECTOR
slides during operation, a spiraled section which contains
the engaging GRAPPLE, a space for the MILL CONTROL
PACKER, and a lower connection to accept the GUIDE.

The GUIDE is usually flush with the outside diameter of

the Casing Patch, and cut lipped. The primary purpose of
the Guide is to assist smooth entry of the fish into the catch
area of the patch. A secondary function is to maintain the
inner working parts in position.

The inner working parts of the Bowen Packer Type

Casing Patch are the GRAPPLE, PACKER, MILL
CONTROL PACKER AND PACKER PROTECTOR.

The GRAPPLE is essentially a cylinder with wickets in

its inside diameter for engaging the fish, and spirals on its
outside diameter to mate with the spirals in the Bowl. Both
the wickets and the spirals are made with a left-hand lead,
which allow release by right-hand rotation. The Grapple
has a series of longitudinal slots which allow the Grapple to
flex diametrically during operation.

The PACKER is a double lipped sleeve type packer,

molded in one piece from synthetic rubber compound. The
material is chosen to include the best combination of
properties for general oil well service. It withstands most
well fluids; has good resistance to gas invasion, and
abrasion.

In service, the outside of the Packer seals against the

inside of the Bowl. The upper lip is protected from damage
by the Packer Protector, until the entering fish pushes the
Packer Protector up out of the way.

The MILL CONTROL PACKER serves the dual

purpose of milling off burrs from the outside of the fish as
it enters the assembly and serving as a special key to key
the Grapple to the Bowl. The Grapple is free to move up
and down sufficiently to engage or release the fish, but is
prevented by the Control Finger from rotating. Thus, the
torque required to release the assembly may be transmitted.

 Bowen Lead Seal Casing Patches
(PATENTED)

GENERAL DESCRIPTION
The BOWEN LEAD SEAL CASING PATCH
is an external catch tool designed to engage a
previously prepared fish, pack it off permanently
and become a part of the repaired casing or tubing.

It consists of two body parts and nine internal

parts. All parts are manufactured from carefully
chosen materials of the most suitable type and
grade for each part.

BOWEN LEAD SEAL CASING PATCHES

will not restrict the bore of the casing or tubing
which is being repaired. They are available in two
types: Sizes for Standard Service and sizes for H2S
(hydrogen sulfide) Service (See Specifications).

USE
As indicated, the B0WEN LEAD SEAL
CASING PATCH is specifically engineered to
effectively engage and pack off a string of casing
or tubing. After the Lead Seal Casing Patch has
been set in position, it ordinarily becomes a
permanent part of the string and is usually
cemented in place.

Where the upper portion of a casing string

becomes ruptured or disoriented from the lower
portion such as by faulting of the formation, caving
of the formation, crushing or rupture, the upper
portion must be removed. New casing is then
replaced, the Lead Seal Casing Patch forming the
patching means between the old and new strings.

CONSTRUCTION
The Lead Seal Casing Patch is constructed in
the most basic manner to perform the functions of
engaging the fish, setting the Seals, or releasing
during operations should this become advisable.

The working parts are a Grapple Carrier,

Grapple, Grapple Control, Control Set Screws,
Lead Seals, Center Seal Ring and End Seal Rings.

 Bowen-Lebus Anchor Washpipe Spear
(PATENTED)

GENERAL DESCRIPTION
The Bowen-Lebus Anchor Washpipe Spear is
specifically designed for the purpose of aiding in
washing over and retrieving stuck drill stem, when
stuck off bottom, with safety to prevent the
dropping of the washed over and freed fish. This
can be accomplished in a single round trip, thus
effecting a considerable time saving.

The Bowen-Lebus Anchor Washpipe Spear

when in service is always in position to
automatically catch the fish off bottom, when
being run into the well, while being raised or
lowered to make kelly connections, or when
coming out of the hole.

The Bowen-Lebus Anchor Washpipe Spear is

one of the most versatile tools ever designed for
washover fishing operations. The method of
anchoring this Spear inside the Washpipe is to
expand the catching slips with a threaded tapered
cone and without using a special landing collar or
nipple for making connection with the fish.

When the Washpipe Spear is anchored

properly inside the washpipe, it will not release
due to rotation of the washpipe and Spear. Neither
will it release by the application of any amount of
weight applied against the Spear slips while being
lowered into the well, but only after the operator
has connected onto the fish by right-hand rotation
where this is required. After connecting onto the
fish by right-hand rotation, the slips of the
washpipe Spear may be released by continued
right-hand rotation and tension load on the
Washpipe string. If the washover starts as soon as
the washpipe will turn over the spear, the slips will
drag, causing excessive wear on the slips.

 Bowen-Lebus Unlatching Joint

GENERAL DESCRIPTION AND USE

The BOWEN-LEBUS UNLATCHING JOINT is a
unique multi-purpose tool. It may be used as a
Setting or Running Tool; a Safety Joint or in any
operation which requires a tensile and torque load
transmitting device, which may be released and re-
engaged at the operator's option.

The Bowen-Lebus Unlatching Joint is particularly

well suited for use as a companion tool to the well
known Bowen-Lebus Anchor Washpipe Spear.

The Bowen-Lebus Unlatching Joint may be

dressed for either right-hand rotation, left-hand
release or right-hand rotation, right-hand release.
This eliminates the necessity for a separate tool for
each. Since a combination of torque and vertical
pull is required to release the tool, full torque may
be applied in either direction during operation. The
tool will not release accidentally.

Bowen-Lebus Unlatching Joints are available in

all sizes from 3-1/4” O.D. through 7-3/4” O.D.
Additional sizes may be furnished on special
request.

OPERATION
The BOWEN-LEBUS UNLATCHING JOINT is
designed primarily for use with wash pipe and the
ANCHOR WASH PIPE SPEAR. It is a means of
allowing the wash pipe spear to be removed from
the well with the wash pipe. The unlatching joint is
operated by predetermined movements of the wash
pipe because the spear slips are firmly set to the
inside wall of the wash pipe when the unlatching
joint is unlatched and moved with it. To remove the
wash pipe spear from the hole, the unlatching joint
is expanded upward to break the snap bar (see
figure 1-B, page 2) and to set the spear slips.
Lowering the drive body while applying torque
moves the drive body into the unlatched position.
From this position the wash pipe and wash pipe
spear are free and can be removed from the hole
(see figure 1-B, page 2). The unlatching joint's male
stem is now firmly engaged to the stuck fish,

Weatherford Fishing Tool Manual

January, 2003 144
 the joint's drive body is engaged to the wash pipe
spear. The joint will automatically re-engage into the
latched position when the drive body is lowered over
the male stem while applying right-hand torque.

If the joint is dressed for left-hand unlatching, the

joint's drive body is torqued to the left (see figure 3,
page 3). If the joint is modified for right-hand
unlatching, the drive body is torqued to the right (see
figure 2, page 3).

Right-hand unlatching is used for deviated holes

where applying left-hand torque to the unlatching
joint might possibly unscrew the wash pipe above the
BOWEN-LEBUS UNLATCHING JOINT.

NOTE: The Beveled Latches are designed to prevent

movement of the drive body to the left.

RIGHT-HAND LATCHING
AND UNLATCHING

Figure No. 2, page 3, shows Beveled Latches

inserted into windows on the BOWENLEBUS
UNLATCHING JOINT for right-hand latching and
unlatching. To latch the joint, the drive body is
lowered over the male stem while applying right-
hand torque. The drive key engages Slot A and
drops until it engages Surface B. The drive body
continues to rotate to right, passing over the Beveled
Latch until it engages Slot D and moves into the
latched position.

To unlatch expand the joint to its upper latched

position with a pull to set the wash pipe spear slips.
Lowering the drive body while applying right-hand
torque allows the drive body to move to the right,
passing over the Beveled Latch, engaging Surface
C. Pulling up on the drive body causes the drive key
to engage Slot A, unlatching the joint.

RIGHT-HAND LATCHING AND

LEFT-HAND UNLATCHING

Figure No. 3, page 3, shows a Keyway Plug inserted

into the window on the BOWEN-LEBUS
UNLATCHING JOINT for right-hand latching and left-
hand unlatching. To latch the joint, the drive body is
lowered over the male stem while applying right-
hand torque. The drive body's drive keys engages
Slot A and drops until it engages Keyway B. The
drive body continues to move to the right until the
opposite drive key engages the Keyway Plug and
moves into the latched position.

 Bowen Surface Bumper Jar
GENERAL DESCRIPTION

The BOWEN SURFACE BUMPER JAR is especially

designed and engineered to be installed in the drilling string at
the surface. Its presence permits the operator to deliver sharp
descending impacts or (downward) jarring blows against the fish
at its stuck-point. By a simple adjustment, the BOWEN
SURFACE BUMPER JAR may be set to deliver very light
blows or blows of very high impact.

USE
The BOWEN SURFACE BUMPER JAR may be used to
great advantage in any situation where the downhole running
string (drilling, fishing or washover) becomes stuck, and a heavy
downward blow is required to release it. The BOWEN
SURFACE BUMPER JAR is often used to free keyseated drill
pipe and drill collars.

It is also used to initiate abrupt jarring blows down the string

to actuate Drilling Bumper Subs, Bumper Safety Joints and other
similar downhole bumping tools.

The BOWEN SURFACE BUMPER JAR is particularly

useful for transmitting very heavy downward blows to effect the
release of grappling tools such as Overshots or Spears, in
situations where the grapples or slips have become imbedded in
the fish, or become fouled due to repeated and prolonged
downhole jarring.

In many instances, the BOWEN SURFACE BUMPER JAR

has been successfully utilized, where all previous methods
failed.

CONSTRUCTION
Basically, the BOWEN SURFACE BUMPER JAR is
composed of a Mandrel Assembly which works in conjunction
with a Bowl Assembly.

The Mandrel Assembly is composed of a Top Sub, Mandrel

and Friction Mandrel.

The Bowl Assembly consists of a Bowl, Bowl Extension,

Bottom Sub, Knocker Sub, Friction Slip Spacer, Control Ring,
Control Ring Plug, Seal Insert and Washpipe.

 Fishing Wire-Line / Not Parted

There are two options in fishing stuck logging tools; the cable - guide
method (pg. 158) and the side-door overshot (pg. 159)

It is critical that you can identify what is stuck; the logging tool or the
wire-line. If you do not know for certain use the cable-guide method.
The cable-guide method is much slower but is also much safer.

Listed below are the situations that I would recommend NOT to run
the side-door overshot.
1. any radio-active logging tool
2. any directionally drilled hole
3. any line-stuck situation
4. any depth below 3000’
5. any wire-line with large O.D. Quick Connect

Bowen recommends the side-door overshot in cased hole situations

 Fishing Wire-Line /Parted
If you are unfortunate enough to have parted wire-line in your well in
casing or open-hole, you are one bad decision from junking your well.
Be very deliberate in making any decisions and involve people that
have successfully fished wire-line in casing or open-hole.

A person might think that wire-line when parted or pulled into will fall
down the hole and ball-up. Wire-line (slick-line, swab-line, electric
logging cable) will stand up in the hole very well. The rule of thumb
that I use is the 10% Rule - wire-line will stand up at 90% or more of
its original height in the well. Shrinkage or stacking out will be 10% or
less. The reason that wire-line will stand up is that these steel wire-
lines come to your location on a drum. The steel gains a memory of the
helix of the drum and when parted in the hole, the wire will try to
return to the helix of the drum it was stored on. This memory makes
the wire-line stand up in the hole.

The recommended fishing procedure for parted wire-line is as follows:

Rope Spear with appropriately sized barbs-RUN ON PIPE
Open Hole - Never use stop
Cased Hole - Use Stop Ring
Have a selection of rope spears on location; center spear, two prong
grab, crank-shaft bend and etc.

Be prepared to make a number of trips as the fishing process is actually

a trial and error to find what works best in this well, with this wire,
under these conditions.

A person might think that you could run wash-pipe and wash-over and
recover large amounts of wire-line. What I have found to be the case is
that the wire will ball up and bridge off about one foot up in the shoe
and then twist into. When you can no longer make hole you will trip
out. The balled up wire in the shoe is a mirror image of what was left
behind in your casing. I do not recommend running wash-pipe to
recover wire-line in casing or open-hole.
