fish, centralize it, then properly guide the fish into the bowl. Oversized Guide – When the hole size is considerably larger than the diameter of the fish, theremay be sufficient room for the overshot to pass alongside of the fish without engaging it. I n this case, an oversized guide can be used to assure fish engagement and to properly guide the fish into the overshot. ExtensionSubs– When the upper portion of the fish is damaged or otherwise cannot be engaged, an extension sub can be used to allow the overshot to be lowered further over the fish to assure proper engagement and pack-off. The extension sub is assembled between the top sub and the bowl, and is available in lengths from 24 to 60 inches. Overshot Milling Shoe – Used in place of the standard guide, the overshot milling shoe allows the top of the fish to be milled clean. This removes excessive burring or jagged edges and assures proper grapple engagement andpack-off. Overshot Mill Extension – The mill extension is used with the standard guide. It is assembled between the bowl and guide and, like the overshot milling shoe, allows the topof thefish to bemilledclean. HollowMill Container and Mill Insert – The Hollow Mill Container provides a means to dress thefish and recover the fish with a standard Overshot in one trip. The Hollow Mill container is located between the Overshot Bowl andStandard Guide. A Mill Insert, dressed with Tungsten Carbide to the desired milling diameter, is placedinsidethe lowermost section of the Hollow Mill Container andis secured in place by theStandard Guide. This will allow for the fish to be dressed prior to entering theOvershot for recovery.
LockRings& Spacer Rings – A lock ring assembly can be used to prevent unscrewing of the top subfrom the bowl during left-hand rotation of thefishing string. Lock rings comein pairs and are assem-
bled between the top sub and the bowl.Whenselectingaspiral grapple andtype A packer, the spacer ring must be used with the lock ring assembly to keep the typeA packerinthecorrectposition.

External Catch –
Die Collars
Die Collar The Gotco DieCollar is an external catch fishing tool designed to retrieve tubular members from thewell bore.
Construction
Assembly and Operation
The Die Collar is manufactured from high grade alloy and specially heat treated. The hardened cutting teeth (wickers) are machined on a shallow taper (approximately 3 /4 inch per foot) to providean excellent grip and positive engagement. Plain watertight wicker's are furnished as standard equipment. Fluted wickers are also available on request. Die Collars are available with plain, lipped, or mill type bottom, or with threaded bottom for attaching a standard lipped or oversized guide.
Assemble the Die Collar to the bottomof the fishing string. Run in the hole until reaching the fish. Apply minimum weight (less than one point) and rotate sufficiently to allow the wicker threads to become embedded in the exterior surface of the fish. Caution: Be
careful not t o apply excessive weight or to rotate excessively. This could cause damage to the wi ckers. Once the
fish has been securely engaged, it can be liftedfrom the hole.
Standard Components A standard or oversized guide can be assembled to the bottom of the Die Collar, if it has been ordered with the optional lower thread. When the hole size is considerably larger than the diameter of the fish, there may be sufficient roomfor theDie Collar to pass alongsideof the fish without engaging it. In this case, an oversized guide can be used to assure fish engagement and to properly guide the fish into the Die Collar. Standard Die Collars are supplied with right-hand threads. Left-handthreads are available on request at no extra charge. When extra long Die Collars (those having a catching range considerably larger than the standard sizes) are requested, it may be necessary to provide atwo or three piece welded assembly. Ask your Gotco sales representative for expert adviceon ordering.

Junk Catchers – Reverse Circulating Junk Basket
Reverse Circulating Junk Basket The Gotco Reverse Circulating J unk Basket (RCB) is a junk retrieval tool designed to removeall types of objects from the bottomof thewell bore. This superior tool removes such items as slips, hand tools, bit cones, and any other small pieces of junk from the well. The RCB uses reverse circulation to aid junk recovery. Construction The tool consists of atop sub, barrel assembly, catcher, and shoe. The barrel assembly con-
sists of an inner and outer barrel, valveseat, cup, andball. A lift sub is also provided to assist in handling.
Assembly and Operation Make up the junk basket to the bottom of the string and run into the hole. When the tool is approximately 10 feet from the bottom of the hole, the ball is dropped down the drill pipe. The ball will position itself in theball seat and reverse circulation will begin. Circulateand begin coring. Combined with the reversecirculation, this guarantees that any
junk on thebottomispumped into the barrel and caught by the catcher assembly. The tool is removed from the hole after cutting 10 to 20 inches of core.
Optional Components and Accessories Shoes - Four types of shoes are available to fit the Reverse Circulating JunkBasket. TypeA mill shoe is supplied as standard equipment with the cutting teeth dressed with hard metal and has side wings. The typeA mill shoeis used where the formation is relatively soft and thefish is a loose piece. Type B mill shoe is equal in design to the type A shoe, however, it is hard faced with Gotcoloy a sintered tungsten carbide in an extremely tough matrix which will effectively and rapidly mill up junk during the fishing operation. This shoewill cut on O.D., I.D. and bottom. Type C mill shoe is also hard faced with Gotcoloy, however, is designed with a flat bottom, and

the Gotcoloy is placed on the inner faceand the outer face. This design is used to mill up junk and is extremely effective for cutting cores. Type B or type C Gotcoloy dressed milling shoes are used if theformation is hard or if thefish is embedded in the formation. Use of thesetwo designs also cuts away protruding excess metal to allow free entry of the junk into thebasket. Finger Shoe- For retrieving loose junk on the bottom of the hole which may exceed the maximum catch of the RCB can be retrieved by use of a finger shoe assembly. The assembly consists of a shoe extension andthe finger replacement. The entire assembly is used in place of a mill shoe. The fingers are designed to close in beneath the fish when slowly lowered during rotation. Finger replacements can be replaced easily and are very inexpensive. Magnet Inserts - The RCB can be easily convertedto a fishing magnet by removing the catcher assembly and replacing it with a magnet insert. The insert still allows direct or reverse circulation and can beused with A, B or C type shoes, or special shoes designed to customer specifications. The magnet insert is the same design as the Gotco Fishing Magnet and by adding a top sub to the magnet insert, it can be used independently as a fishing magnet.

Junk Catchers – Fishing Magnet
Fishing Magnet The Gotco Fishing Magnet is a junk retrieval tool designed to effectively removemetal particles, shavings, and debris from the bottom of the well bore. Theprocess of retrieving small, oddly shaped objects is one of the most frequent and most difficult fishing jobs.Typically, theseobjects are the result of bit failures that leave cones and cutters in the hole, or are an accumulation of mill cuttings, or are simply accidental droppings of unmillable objects into thehole. In these cases, the fish is nearly always an odd-shapedobject that cannot beengaged in the normal manner. Fishing magnets successfully removethese small objects from the hole bottom. The tool’s design incorporates generous circulation holes that wash away the cuttings and other debris that otherwise would prevent contact with the magnet. Fishing magnets canberun on either wire lineor pipe.
Construction The fishing magnet is constructed from steel specially selected for its ability to conduct the necessary magneto-motive forces. The magnet element is one of the most powerful permanent magnets available. Used properly, it will never lose its

charge. A variety of shoes are available to accommodate any retrieval situation. Caution:
Wire Line Adapter – An adapter is available to install between the magnet and the cable heador socket. Magnet Charger – The Gotco Magnet Charger provides the highest strength possible for recharging your fishing magnets. While magnets should not lose their effectiveness during normal handling and operation, conditions exist which canreduce their charge. Welding a magnet sub jects the magnet circuit to electrical current which can adversely affect the charge. Similarly, storing the magnet in the vicinity of electric motors, or bringing magnets too close to each other can be detrimental to the magnet’s strength. Recharging is quick and simple. There is no limit to the
number of timesa magnet can be recharged, and with proper handling a recharged magnet will retain maximum strength indefinitely. Keepers – Keeper bars are recommended when magnets are stored. They are placed on the faceof the magnet and will consumemost of the flux generated by the magnet element. This will reducethe potential for the attraction of miscellaneous metal items or particles. Keepers canbesafely and easily removed at any time. Air Shipments– If shipping by air, consult your freight forwarder. Special handling is required by most airlines when shipping magnetized items.
Magnets are charged while in the assembled state and shoul d not be disassembled. Di sassembly is dangerous and can cause serious i njur y due to the extr eme forces generated by the magnet element.
Gotco Fishing Magnets
Assembly and Operation
Gotco Fishing Magnets
No assembly is required other than selecting the desired shoe and installing it on the lower end of the magnet assembly. Make up the magnet assembly to the bottomof the fishing string. Run in the hole, and hold the magnet 6 to 12 inches above the fish. Circulate generously to wash away cuttings. Reduce circulation, lower the magnet to the fish, androtate slightly to obtain good contact. Cut off circulation and lift the magnet from thehole.

The jar will begin to open slowly asthe piston meters the hydraulic fluid in the jar. Once the jar has opened approximately half of its full stroke, the piston will release and the jar will suddenly open fully, releasing theenergy stored in the stretched drill string, delivering the desired impact. The amount of impact is determined by the amount of stretch applied to the string. This provides the operator with complete control over the impact applied. No adjustments to the tool are required. Once the jar has been tripped it can be quickly reset by lowering the string and allowing the jar to close. Heavy-duty splines allow for full torque transmission at any time. For maximum effectiveness, also use a jar impact amplifier.

Assembly and Operation
Bumper Sub
30
The fishing bumper sub is installed in the fishing string immediately above the fishing tool or safety joint. To apply a sharp downward blow, mark the pipe at surface to indicate open and closed positions of bumper sub. Raise fishing string to open bumper sub and allow for some additional pipe stretch. Drop string sharply and stop with the brake approximately 4 to 6 inches above the closed position of bumper sub. As the fishing string springs downward, the bumper sub will deliver a sharp downward blow. To apply a solid downward blow, raisefishing string to open bumper sub plus exert a slight stretch in string. Drop full weight of pipewithout braking to deliver a strong downward blow. To apply an upward blow, mark pipe at surface to indicate open and closed positions of bumper sub. Raise fishing string to open bumper sub plus exert moderate strength in string. Drop string by the amount of pipe stretch only and catch it with the brake. As pipe recoils at the bottom of the hole, the bumper sub will deliver asharp upward blow.

Jar Impact Amplifier – Accessory Tools
Jar Impact Amplifier The Gotco J ar Impact Amplifier is a vital accessory tool designed to berun with theGotco Hydraulic Fishing Jar. It will acceleratetheupward motion of thedrill collars and the fishing jar allowing theoperator to apply significantly greater impact to thefish.This is particularly helpful in deviated holes where friction may reducethe impact of thejar or in shallow holes where there is insufficient string lengthto provideadequate stretch to the running string. Acting also as a shock absorber to the rebounding string, thejar impact amplifier will protect tools and stringfromdamage.

Construction Manufactured from high strength alloy andheat treatedfor maximum toughness, the jar impact amplifier is both rugged and reliable. Heavy splines allow theapplication of full torque and a generous through bore offers unrestrictedcirculation at all times. Operation The jar impact amplifier should be located in the string immediately above the drill collars. No presetting is required. When a stretch is applied to the string, the jar impact amplifier fluids are compressed, storing additional energy. When the jar trips, this energy is released. The tool will automatically reset, each time the jar trips, and will continue to operate as many times as necessary to freethe fish.
Service Kit A service kit is required to properly redress and fill the hydraulic jar. One kit will service all Gotco Jars and Jar Impact Amplifiers.
Setting Tools A mandrel body setting tool is required for each size of jar impact amplifier. Setting tools are used to properly position and set the standard copper back-up and non-extrusion rings.

Thecritical seal points of theMandrel and Washpipe areequipped with a seal-ring assembly consisting of an Oring, Non-Extrusion Ring and Seal Protector Ring.This Seal Ring set keeps the diametrical clearance at the seal points to an absolute minimum as hydraulic pressure is applied from either direction in the tool. This greatly increases the life of theO-Ring and seal set by prohibiting O-Ring extrusion.

Boot Basket (Junk Sub) – Milling
Boot Basket (Junk Sub) The Gotco Boot Basket (Junk Sub) is an accessory tool used in milling or drilling operations. It is designed to prevent cuttings that are too heavy to becirculated from settling to the bottom of the hole.
Construction Boot baskets are manufactured from high-strength heat treated alloy steel to withstand wear. Heavy-duty ribs are attached to the cup to prevent it from being crushed and to guide thetool through tight places while tripping out of the hole. These ribs are not welded to the main body of the tool, further enhancing its strength.
Assembly and Operation Boot baskets are useddirectly above the mill or drill bit. On severe milling jobs, it is customary to run two or three baskets in tandemabove the mill. This tandem running not only increases the capacity to remove the cuttings, but also provides extra stabilization for the mill. Boot baskets can berun in either open hole or insidecasing. When the basket is working inside a casing, hardfaced pads, dressed to the same O.D. as the mill or bit, should be used.
Optional Components and Accessories
Boot Basket (Junk Sub)
The standard boot basket is a welded assembly with a 10 inch deep cup. L ong and extra long baskets are available; these provide a 20 or 30 inch deep cup.

Whenordering,pleasespecify: • Nameandassemblypart number. • Casing size andweight. • Topconnection, if nonstandard.
Manufactured from specially selected alloys, designed specifically to resist wear, the casing roller can be used to restore any size and weight of casing. The casing roller consists of a mandrel with a box connection up and threeheavy duty rollers. The I.D. of each roller is precision ground to assure proper rotation on the mandrel. Securing the rollers to the mandrel is a nosecone which is retained by large ball bearings. A throughbore provides circulation capabilities. Tools may be run effectively at relatively slow rotary speedsandare available with lefthandconnectionsif desired.
Operation The casing roller should be made upto the bottomof the drill string. Lower the pipe and rotate slowly until the damaged section is reached. Start circulation, increaserotation speed and continueto lower slowly. The tapered nosecone will enter and guide the tool, allowing it to open the collapsed portion to its original size. Use of too little pressure will wear the tool without restoring thecasing. Be sure adequate downward pressureis maintained. Add drill collarsif thestringweightis insufficientto assurecontinued downward progress.

Remedial and Repair – Casing Scraper
Casing Scraper
Gotco Casing Scrapers
The Gotco Casing Scraper is designed to remove scale, mud cake,cementsheath, embeddedbullets,andotherforeignmaterial fromtheinside of thecasing wall. Maintaining acleancasing I.D. is vital to the efficient operation of down-hole tools used in drilling thewell. The resulting smooth surfaceproperly prepares the casing for subsequent down-hole operations such as packer settingandsqueezetools. Construction Manufactured from alloy steel and heat treated to provide strength and durability, each scraper must pass rigid nondestructive testing to ensure the highest quality product. Each tool has six blades specially aligned on the body to provide themaximumcutting surfaceareafor vertical and rotational scraping. The blades are designedto give optimum shearing action with the least amount of restriction to returning well fluid. The splined body provides absolute safety and security by locking each blade onto an integral part of the scraper. This unique body design also allows for ease of maintenance and dressing of the tool. All casing scrapers can be easily set for positive or spring loaded scraping action. Even when set positive to drift, the spring loaded design will effectively scrape multi-weighted casing within the well. All blades are cast steel and heat treated to provide long lasting service life.
