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 (10,000â&#x20AC;&#x2122; 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.

Weatherford Fishing Tool Manual January, 2003

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, manufacturerâ&#x20AC;&#x2122;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.

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 â&#x20AC;&#x153;Identify the Problemâ&#x20AC;? 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 drillstring 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 drillstring 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. Weatherford Fishing Tool Manual January, 2003

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. Weatherford Fishing Tool Manual January, 2003

CEMENTED STICKING - When pipe is cemented in place, Jarring is not an option except on a very short section (10â&#x20AC;&#x2122; 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 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 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 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 (10,000â&#x20AC;&#x2122; or deeper) with high density (15 PPG and heavier) whole mud as the workover fluid.

Force

Buoyancy is commonly and correctly thought of as a force tending to make a submerged object float, but the way buoyant force is applied is often misunderstood. There is a simple demonstration of the application of buoyant force -- and of the lack of it -that clearly illustrates the principles involved.

As shown in the example above, a beaker maybe fitted at the bottom with a rubber pad. A hollow steel cylinder is beveled on each end -- the bevel being internal on one end and external on the other. When the cylinder is held in place with the external bevel down (as in “A”) and the annulus filled with

mercury, fluid (hydrostatic) pressure is applied to the end of the cylinder and this force causes the cylinder to rise and float when the cylinder is released. In contrast, when the cylinder is held in place with the internal bevel down and the annulus filled with mercury as in “B,” the fluid pressure has no end area on which to act and there is no axial force. Consequently, the cylinder does not rise when released. This illustration leads to some interesting but not always accepted conclusions. In “B,” there is fluid displaced by air and steel but no buoyancy. In other words, the common concept that buoyancy is equal to the weight of fluid displaced is true only sometimes!! Buoyant forces exist only when there is an exposed end or crosssectional area to which hydrostatic pressure can be applied vertically. It follows that the lower end of a submerged steel tube must be in compression, and that calculations using buoyed weight per foot are technically incorrect for calculating axial forces in a tubular string. *The demonstration was originally conceived by J. Paul Sloan, then of Gulf Oil Corp, and now retired

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 pipeâ&#x20AC;&#x201D;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 Differential Temperature Log

Differential Temperature Log

Temperature in the well bore 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 reestablished.

ln pipe recovery work the most common reason for the running of the Differential Temperature Log would be to determine lost circulation zones. The Differential Temperature Log consists of an absolute temperature curve, differential temperature curve and collar log—recorded simultaneously. An extremely sensitive downhole probe records minute temperature changes from O to 400°F. It sends this information to a surface panel which records it for interpretation.

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 survey, the temperatures recorded down to the lost circulation zone will tend to be cooler than the temperature of the formation. Below the lost circulation zone, the fluid has been stagnant in the hole and will probably be at formation temperature. A distinguishable change in the temperature gradient curve is notified at the lost circulation zone. In open hole logging, the theft zone will be indicated by a drop in temperature as the heat sensor passes through it. When logging inside drill pipe near bottom, the theft zone will be indicated by an increase in temperature as the heat sensor passes through it. In either case, the lost circulation zone is established as to depth and thickness. Differential Temperature Tools are available in 1-3/8"and 7/8”O.D.

BOWEN SERIES 150 RELEASING & CIRCULATING OVERSHOT (PATENTED) The BOWEN OVERSHOT has gained worldwide 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.

Weatherford Fishing Tool Manual January, 2003

BOWEN OVERSHOTS are continually developed to new standards of strength and efficiency and are expertly constructed of the highest quality material. Each BOWEN SERIES 150 RELEASING AND CIRCULATING OVERSHOT is a compact unit designed to engage, pack off and pull a specific size of tubing, pipe, coupling, tool joint, drill collar or smooth O. D. tool. Through the installation of proper undersize parts, they may be adapted to engage and pack off any smaller size. Bowen course thread Overshots are designed for easier assembly and maintenance. The Bowen "CT" Overshot has a course ACME thread on the upper end of the Bowl where the Top Sub is attached and at lower end where the Guide is attached. The course thread allows much easier field assembly and will stand more abuse than the fine series currently offered. The internal parts are completely interchangeable with existing Bowen Overshots. Cross over bushings can be provided from fine thread series to course thread series, allowing full use of Bowls, Top Subs, and Guides currently in stock. (See spec. page 29 for Course Threads.) All sizes of BOWEN SERIES 150-RELEASING AND CIRCULATING OVERSHOT are available in FULL STRENGTH or SLIM HOLE TYPES. Despite the extremely small outside diameters of FULL STRENGTH TYPE OVERSHOTS, they are engineered to withstand the pulling, torsional and jarring strains which must be exerted by modem machinery, to release and retrieve a lost fish. The SLIM HOLE TYPE OVERSHOTS have reduced outside diameters, as compared to the FULL STRENGTH. They are used to perform pulling jobs in tight holes where no other outside catch, releasing fishing tool can be run.

USE A BOWEN SERIES 150 RELEASING AND CIRCULATING OVERSHOT is used to engage, pack off and retrieve twisted-off or lost tubing, drill pipe, coupling, tool joint, casing or other similar fish.

CONSTRUCTION The BOWEN SERIES 150 RELEASING AND CIRCULATING OVERSHOT is composed of three outside parts; the Top Sub, Bowl, and Guide. The Basic Overshot may be dressed with either of two sets of intemal parts, depending on whether the fish to be caught is near maximum catch size for the particular overshot. If the fish diameter is near the maximum catch of the Overshot, a Spiral Grapple, Spiral Grapple Control and Type "A" Packer are used. If the fish is a tubing collar, a Type "D" Collar Packoff Assembly will replace the Type "A" Packer. If the fish diameter is considerably below maximum catch size (usually 1/2â&#x20AC;?), a Basket Grapple and a Mill Control Packer is used.

GRIPPING AND RELEASING MECHANISM The Bowl of the Overshot is designed with helically tapered spiral section in its inside diameter. The gripping member (Spiral Grapple or Basket Grapple), is fitted into this section. When an upward pull is exerted against a fish, an expansion strain is spread evenly over a long section of the fish. No damage or distortion results to either the fish or the Overshot. This design permits a far stronger tool with a smaller outside diameter than is possible with an overshot that employs a single tapered section which supports slips. A Spiral Grapple is formed as a left-hand helix with a tapered exterior to conform with the helically tapered section in the Bowl. Its interior is wickered for engagement with the fish. A Basket Grapple is an expansible cylinder with a tapered exterior to conform to the the helically tapered section in the Bowl. Its interior is wickered for engagement with the fish. Three types of Basket Grapple are available to meet the need for catching various types of fish: The Plain Basket Grapple is standard, and will always be furnished unless another type is specified. It is wickered for its entire interior length. It is used to catch any plain single diameter fish. The Basket Grapple with Long Catch Stop has an internal shoulder located at the upper end, to stop the fish in best catch position. It is designed to stop and catch an upset, or box section of a tool joint, with sufficient length left below the Grapple to allow the joint or upset to be packed off with a Basket Mill Control Packer. The Basket Grapple with Short Catch Stop has a double set of wickers, of two different internal diameters. It is used to stop and catch a coupling with a ruptured piece of pipe engaged in its upper end. The upper set of wickers will catch the ruptured pipe, and act as a stop against the coupling, while the lower set of wickers will catch the coupling. The coupling will be stopped in best position to be packed off by the Mill Control Packer. Grapple Controls are of two types: Spiral Grapple Controls are used with Spiral Grapples; Mill Control Packers are used with Basket Grapples. Grapple Controls are used as a special key, to allow the Grapple to move up and down during operation while simultaneously transmitting full torque from the Grapple to the Bowl. Spiral Grapple Controls and Basket Grapple Controls are plain. Mill Control Packers include a packoff. See Packoff Mechanism below for a complete explanation. In operation, the Overshot functions in the same manner, whether dressed with Spiral Grapple parts or Basket Grapple parts. During the engaging operation, as the Overshot is rotated to the right and lowered, the Grapple will expand when the fish is engaged, allowing the fish to enter the Grapple. Thereafter with rotation ceased and upward pull exerted, the Grapple is contracted by the

Weatherford Fishing Tool Manual January, 2003

tapers in the Bowl and its deep wickers grip the fish firmly. During the releasing operation, a sharp downward bump places the larger portion of the Bowl tapers opposite the Grapple smaller tapered portion, 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.

PACK-OFF MECHANISM The type of Packoff used depends on how the Overshot is dressed, and the operator's choice. When the Overshot is dressed with a Spiral Grapple, a Type "A" Packer is used. The Type "A Packer is a sleeve type. It seats at its O. D. against the inside of the Bowl. It has an internal lip which seals around the fish. Each Type "A" Packer is designed to pack off a specific size. A Type "A" Packer should be ordered for each catch size Spiral Grapple. A Mill Control Packer is used when the Overshot is dressed with a Basket Grapple. The Type "R" Mill Control Packer is used when a packoff is required. The unique double lip seal of the Mill Control Packer provides a positive seal of the fish. The Packer is self energized and is retained within the Mill Control by a lower second sealing lip and requires no adhesive for retaining the Packer. The Type "R" is most commonly used. It has a replaceable inner seal and a replaceable outer seal. The inner seal and the outer seal may both be replaced in the field when required. The Type "R" Mill Control (with mill teeth) is available. Mill Control Packers are designed to remove small burrs and rough breaks only.

All Mill Control Packers are manufactured to pack off a specific size. One should be ordered to match each size Basket Grapple. Mill Control Packers when used, replace a Plain Basket Control. The Plain Basket Control is used with a Basket Grapple when no packoff of the fish is required. Type "D" Packer assemblies are available to pack off tubing collars in tubing size Series 150 Overshots. The Type "D" Packer assembly consists of a Packer, a Spring and an "O" Ring. It is assembled in the Bowl above the Grapple. Its upper end is sealed in a counterbore in the Top Sub, by the "O" Ring. In operation, its lower end stops the collar in proper catch position, while the integral molded seal enters and packs off the collar threads at the top of the collar. The Type "D" Collar Packer is designed to be used with a Spiral Grapple, in place of a Type "A" Packer, where the collar being fished is too short to allow effective catch and pack off length.

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.

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.

Weatherford Fishing Tool Manual January 2003 48

MAINTENANCE Maintenance of Bowen Sucker Rod Overshots is simple, but important. After each use, the tool should be disassembled, inspected, repaired as required and reassembled. 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 reassembled. To prevent rust or deterioration, either grease or paint the exterior.

SERIES 70 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.

Weatherford Fishing Tool Manual January 2003 56

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.” Complete Assembly

Weatherford Fishing Tool Manual January 2003 57

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. 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 turns the Mandrel of the Spear down through the 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 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 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 Release Ring and Nut constitute a safety device which resists freezing or jamming. The tool is available in two types -- one known as the Flush Type and the other as the Shoulder Type. A Flush Type Spear can be supplied when the specified

Fig. 13 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.

Retainer Screw

The Bowen Segment Type Spear Grapple is used to extend the catching ability beyond the range of a one piece grapple(see chart below). This grapple consists of a Grapple Body, eight Grapple Segments, two Retainer Rings, six Ring 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 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.

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

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.

Weatherford Fishing Tool Manual January 2003

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.

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.

Weatherford Fishing Tool Manual January 2003

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, specify the required top connection and the Magnet to be used with.

Lipped Guide

Flat Bottom Guide

Cut-Lipped, Flush O.D. Type and Mill Type Guides are available as optional accessories. Order by standard Guide number, specifying type required and Magnet to be used on.

Mill Guide

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. Size 14" 20" Bowen Magnet Charger Complete Assembly 71999 71662 W eight…………………….. 5100 7100 Power Supply Unit Part No. 70973 70973 W eight…………………….. 100 100 Magnetizing Coil Unit Part No. 70974 76663 W eight…………………….. 5000 7000 Input Requirements: 100 Amperes, 208-230 Volts, 50/60 Hz., A.C., Single Phase.

The Bowen Magnet Charger can be used to magnetize fishing magnets up to 14 and 20 inches outside diameter. Proper Charge Regardless of the charging method, a Bowen Fishing Magnet is properly charged when it reads 2500 gausses or more on a commercial gauss meter. Lifting capacity is a function of size, contact area and charge. The gauss meter reads the strength of the charge which does not vary because of the size of the magnet.

ITCO TYPE BOWEN JUNK BASKETS (PATENTED) GENERAL DESCRIPTION The BOWEN JUNK BASKET â&#x20AC;&#x201D; 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.

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

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 â&#x20AC;&#x153;running inâ&#x20AC;? 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.

HOUSTON ENGINEERS, INC. ADVANTAGES: The "DH" Cutter has been designed to washover, cut and recover stuck tubing in lengths of cuts up to 1,500 feet. Unlike most external cutters, the initial run of the rotary shoe and washover pipe is eliminated, thus saving as much as fifty percent of valuable rig time ordinarily required for such operations. The releasability feature virtually eliminates the expensive repair charges normally incurred when the cut cannot be made. Other outstanding features of the "DH" Cutter are: 1. Designed stronger than nominal sized washover pipe. 2. Not necessary to remove the washpipe from the hole before making additional cuts. 3. The overshot assembly, knives, and operation of the cutter in general can be checked with the recovered tubing before stripping tubing from the washpipe. 4. Unaffected by temperature, hydrostatic pressures, fluid movement or pump pulsation.

Sleeve, Knives, Drive Body and either a Slip Dog Overshot or T-Dog Overshot Assembly. The type overshot assembly used is governed by the type of tubing to be cut. A. The Slip Dog Overshot is used on tubing with integral joints such as "CS" Hyd. B. The T- Dog Overshot is used on the standard collared tubing. Both dependable overshot assemblies will catch and release their respective tubing. All releasing operations require only right hand rotation, and the overshots will automatically return to the catch position after releasing. This releasing method allows removal of the kelly for making connections or other operations. The cutting elements of the "DH" cutter are well supported and are tungsten carbide inserted to assure numerous cuts. The knives are protected by the knife actuator until put in the cutting position, and then spring fed to assure proper feeding, eliminating the possibility of excess loading. The lower connection will allow the use of washpipe and/or rotary shoe below the cutter if necessary.

FEATURES: Principal parts of the "DH" Cutter are: Top Sub, Drive Sleeve, Actuator

Assembly Instructions

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. Weatherford Fishing Tool Manual January, 2003

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. Weatherford Fishing Tool Manual January, 2003

141

USE The Bowen-Lebus Anchor Washpipe Spear is designed to be run inside washover pipe. It engages the Fish at its lower end, usually by a threaded connection, preventing the fish from dropping to the bottom when it is washed loose. The Anchor Washpipe Spear will recover drill pipe, drill collars, packers, bridge plugs, etc., that are to be washed over, either off bottom or on

CONSTRUCTION The Bowen-Lebus Anchor Washpipe Spear consists essentially of a Head, Body Stem, Control Cage, Restriction Rings, Slips, Friction Blocks, Choke, Ball Latch, Slip Cone, Ball Latch Cage, Centralizing Lugs and Bottom Sub. The parts that comprise the Bowen-Lebus Anchor Washpipe Spear are manufactured from carefully selected, high grade alloy steel, fully heat treated to obtain the best quality of operation and long life.

bottom, and bring the fish out of the hole, inside the washpipe, after it has been washed loose. This saves additional trips with the fishing string.

Fishing Spears, taper taps or other applicable fishing tools may be run on the Anchor Washpipe Spear to engage the fish.

The Bowen-Lebus Anchor Washpipe Spear is available in all drill pipe sizes from 2-3/8" A.P.I. Regular 3-1/4" O.D. through 5-1/2" A.P.I. Regular 8-1/4" O.D., inclusive. These tools may be dressed with oversize Slips, Restriction Rings, Friction Blocks and Centralizer Lugs, to allow operation in larger sizes than the size for which the tool was designed. Each Slip (part 12) marked with the size range of washpipe inside diameter in which it is used.

The Bowen-Lebus Unlatching Joint should always be run between the Washpipe Spear and the fish.

When the Bowen-Lebus Anchor Washpipe

Restriction Ring (part 4) should be 1/16" smaller than the inside diameter of the washpipe in which they are used. The Friction Blocks (part 5) are marked with size numbers which match the size number marked on the Slips.

Spear is not available, various methods are attempted for the release of a stuck drill stem. Among these are; mixing oil in the drilling mud;

Centralizer Lugs (Part 14-A) are marked with the size number to indicate the inside diameter in which they are used.

inserting jars and bumper subs in the string; using explosives in the string, and as a last resort,

All oversize parts may be changed without completely disassembling the Washpipe Spear.

washing over.

By using the Bowen-Lebus Anchor Washpipe Spear, washing over need no longer be considered as a last resort.

In the larger three sizes JCF-27, JCF-28 and JCF-29, it is important to use a choke (part 15) which has less area than exists between the washpipe and drill collars, or the area between the washpipe and well bore, being certain it is small enough for the rig mud pump to provide adequate fluid to operate the restriction rings.

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 reengaged 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 3-1/4â&#x20AC;? O.D. through 7-3/4â&#x20AC;? 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 righthand 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 lefthand unlatching. To latch the joint, the drive body is lowered over the male stem while applying righthand 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. Weatherford Fishing Tool Manual January, 2003

145

To unlatch, expand the joint upward from the latched position until the spear slips are firmly set. Then, by lowering the drive body while applying lefthand torque allows the drive body to move to the left until the Keyway Plug is contacted. Continue left-hand torque and pull up on the drive body. This will cause the drive body keys to engage Slot A, unlatching the joint. NOTE: The Keyway Plug prevents the joint from unlatching with right-hand torque and movement.

Applying torque to the BOWEN-LEBUS UNLATCHING JOINT will not break the snap bars. They break only when the joint is expanded in tension. After breaking, the snap bar parts remain attached to the drive body and male stem - no jamming, no clogging. LATCHING OR UNLATCHING JOINT Figure No. 6, page 4, shows the LEBUS UNLATCHING JOINT being separated after unlatching. This figure also illustrates joining parts together for latching the joint.

LATCHING OPERATION Figure No. 4, page 4, shows the BOWENLEBUS UNLATCHING JOINT drive body being lowered over the stem while maintaining right-hand torque to latch the joint.

INSTRUCTIONS FOR DRESSING THE JOINT For Right-Hand Release (See Fig. 7, Pg. 5) 1. Remove insert keyway plug (3) and screws(8)

LOCKING JOINT FOR RUNNING INTO WELL

2. Place both beveled latches (4) and springs (5) in latch windows using proper length screws (7).

Figure No. 5, page 4, shows the BOWEN LEBUS UNLATCHING JOINT drive body in the latched position with snap bars and packing stem inserted. The snap bars lock the drive body to the male stem to prevent joint disengagement while running into the well.

NOTE: The latches and latch windows are marked with an "X". When the "X's" are lined up, the latches will be in the correct position. Latches MUST be placed in slots so bevel on latches will allow the drive body to pass over BOTH latches while moving to the RIGHT.

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.

Weatherford Fishing Tool Manual January, 2003

151

The Washpipe, which is connected to the Bottom Sub and moves inside of the Main Maridrel, is sealed from the Main Mandrel by the Seal Insert confining the well fluids within the Washpipe and out of the restraining mechanism within the Bowl. The Main Mandrel, which is hexagon in shape, fits into a correspondingly shaped bore in the Knocker Sub, where it is continuously capable of transmitting torque, while also free to move up and down over its entire 48" stroke. Control of the BOWEN SURFACE BUMPER JAR is exercised by the action of the restraining mechanism of the Friction Mandrel, the Friction Slip, the Friction Slip Spacer and the Control Ring. The Tonnage (the striking force of the jar) is adjusted by setting the Control Ring. Top and Bottom Subs are furnished with a 5 1/2" F.H. connection. The Top Sub is a box connection and the Bottom Sub is a pin connection. A lifting sub is provided for the top connection for the purpose of transporting and/or lifting the Surface Jar. EXPLANATION OF MECHANISM Referring to the illustration on Page 5, it can be seen that the Friction Slip is restricted within the tapered bowl by the Control Ring. Turning the Control Ring to the right or to the left moves the Friction Slip up or down the taper, thereby either increasing or decreasing its ability to expand. There are internal Rings (raised areas) within the Friction Slip which must pass over the external Rings (raised areas) of the Friction Mandrel in order to pull the Jar into its open position and to produce the jarring blow. When the Surface Bumper Jar is being opened or tripped, the Friction Mandrel pulls the Friction Slip into a reduced section of the taper in the Bowl and against the bottom ofthe Control Ring. Hence, depending upon the position of the Control Ring, only a slight pull or a pull of many tons is required to open the jar. When the Surface Bumper Jar is installed at the surface and a straight upward pull is exerted against it, the Friction Slip frictions upon the enclosed friction Mandrel and arrests upward movement while the drill pipe is being stretched. When the upward pull reaches the pre-set tripping tonnage, the Friction Mandrel is pulled through the Friction Slip. The resultant downward surge of the drill pipe in returning to its normal length causes a sudden separation of the Main Mandrel and Bowl assemblies which are free to move apart for the length of its 48 inch stroke and drive the weight of the free pipe against the point where the fish is stuck.

When the Surface Bumper Jar is being closed, the Friction Mandrel pushes the Friction Slip into the enlarged section of the taper in the Bowl and then slides easily through" it. The Control Ring Plug has a projection on its inner end which engages a slot in the Control Ring and prevents it from turning. Removing the Control Ring Plug from the Bowl exposes a port through which the Control Ring may be turned with a Control Ring wrench. Turning the Control Ring to the right moves it upwardly, in turn, moving the Friction Slip into the smaller diameter of the tapered bowl, therefore constricting the rings more and requiring more tons to open the jar. The words "More Tons" are stamped on the right side of the Control Ring Port. Turning the Control Ring to the left moves it downwardly, in turn, moving the Friction Slip into the larger diameter of the tapered bowl, therefore expanding the rings more and requiring less tons to open the jar. The words "Less Tons" are stamped on the left side ofthe Control Ring Port. NOTE: The Surface Bumper Jar should be pulled open at the rig site before it is brought from the field to be serviced. OPERATION In all types of jarring operations, the BOWEN SURFACE BUMPERJAR is installed in the drilling string or fishing string just above the rotary table, or at the joint nearest the table. If circulation is desired, connect the kelly to the top of the jar. If circulation is not required, connect a single joint of pipe above the jar. Sufficient weight (300 to 400 lbs.) should be run above the jar to close and re-set it. Always begin jarring operation with a LIGHT tonnage, gradually increasing the tonnage as the operation proceeds. Set the restraining mechanism to light tonnage by adjusting the Control Ring as indicated by the stencil on the Bowl at the Control Ring Plug. (To adjust the Control Ring, remove the Control Ring Plug and then, using the Control Wrench, rotate the Control Ring to the RIGHT to increase the tripping tonnage or to the LEFT to decrease the tripping tonnage. Take an upward strain on the BOWEN SURFACE BUMPER JAR. When the upward strain is equal to the previously set tonnage, the restraining

Weatherford Fishing Tool Manual January, 2003

152

mechanism will release and allow the Bowl Assembly to descend rapidly with respect to the Mandrel Assembly for 48 inches. This will cause the weight of the stretched pipe to fall downward against the stuck fish. To Free A Stuck Drill String Drill Strings frequently stick on the trip out of the hole by pulling into a keyseat. Install the BOWEN SURFACE BUMPER JAR in the drill string as explained above. Set the Jar for light tonnage and begin jarring operations, gradually increasing the tonnage as jarring proceeds, until the drill pipe is free. CAUTION Do not set the tripping tonnage of the Jar higher than the weight between the surface and the point where it is stuck. If the tripping tonnage is set higher than the weight of the amount of free pipe above the stuck point, it will result in the pipe being pulled tighter into the keyseat. Do not use a load setting that will create a stretch in the drill string that is greater than the stroke of the jar. This could cause an impact within the jar and possibly damage the hook or other rig components. Be aware that a sudden freeing of a heavy fish will allow the fish to drop and strike a jarring blow with the jar. This could also damage the rig. A similar procedure is observed in all cases of stuck pipe. To Actuate A Bumper Sub Many drilling operators employ Drilling Bumper Subs in the drilling string. Also, almost all fishing operators install a Bumper Sub above the engaging tool in a fishing string. When the String, in either case, becomes stuck and the Bumper Sub is ineffective, install a BOWEN SURFACE BUMPER JAR in the string as explained above. Set the Surface Bumper Jar for light tonnage, just enough to open the Bumper Sub. Thereafter, gradually increase tonnage but observe the precaution cited above and do not set the tripping tonnage so high that it exceeds the weight of the free pipe above the stuck point. Continue jarring with the Surface Bumper Jar until the stuck string is free. To Release a Fishing Tool Occasionally, fishing tools or grappling tools such as Overshots or Speaks cannot be released by the normal procedure of bumping down with the weight of the fishing string. This is usually the result of the Grapple or the Slips having become imbedded in the fish or having become fouled due to repeated and prolonged bumping and jarring on the fish.

In such cases, install a BOWEN SURFACE BUMPER JAR in the fishing string as explained above. Set the tonnage at a medium tonnage but do not exceed the weight of the free pipe below the Surface Bumper Jar. If there is a Bumper Sub in the string, set the tonnage high enough to insure that the Bumper Sub is pulled into its fully open position. Open the Surface Bumper Jar to erect the release of the Grappling tool. This will usually require only one or two blows. Precautions Always begin Surface Bumper Jar operations with the Jar set for LIGHT jarring, gradually increasing tonnage as jarring operations proceed. Avoid setting the tonnage of the Surface Bumper Jar to exceed the weight of the free pipe between the Jar and the stuck point. This will usually result in defeating the purpose of the Jar and may stick the pipe tighter. Occasionally, the BOWEN SURFACE BUMPER JAR may become "half-cocked" -where the Jar is neither fully opened nor fully closed. This situation results from having set the tripping tonnage so high that there is insufficient pulling power to trip the Jar and the weight of the pipe above the Jar is insufficient to close it. It is then necessary to break the Jar out of the string, protect the pin connection thread on the bottom, and strike the Jar sharply against some solid object until the Jar is closed. Then, the Control Ring may be adjusted for less tripping tonnage and the operation resumed. NOTE: It is important that the Surface Bumper Jar be opened at the rig site before it is brought in from thefieldfor servicing. MAINTENANCE The BOWEN SURFACE BUMPER JAR normally requires very little maintenance. After each use, it should be thoroughly rinsed out with clear water to remove any drilling fluid that may have been circulated through it. The Jar should be opened so that the surface of the hexagon Main Mandrel may be lubricated with a good grade of heavy weight oil or grease. After lubricating the Main Mandrel, the Jar should be set to minimum tonnage and then closed. The exterior surface may be painted or lubricated to prevent any rust or deterioration.

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 3000â&#x20AC;&#x2122; 5. any wire-line with large O.D. Quick Connect Bowen recommends the side-door overshot in cased hole situations only.

BOWEN SERIES 160 SIDE DOOR OVERSHOTS

Important features of the Series 160 Side Door Overshot are:

Bowen recommends the use of the Series 160 Side Door Overshots when fishing for conductor line or cable tools in cased holes. These Overshots are run in on tubing or drill pipe. By removing the side door in the Bowl, the line can be fed into the tool. After the line is in place, the door is put back into position as part of the Bowl.

•· Eliminates the necessity of cutting the line or cable

•· Eliminates the possibility of lines fouling (this can take place when two lines are in the hole)

•· Provides more positive control than would be possible when fishing with a conventional wire line overshot

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 wirelines 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.
