ACCELERATOR
PURPOSE
Designed to intensify the jarring action and cushion the force on the rope socket.
DESCRIPTION
The accelerator is made up of seven components.
1. Fishneck2. Barrel3. Cap4. Mandrel5. Spring6. End Cap7. Bottom Sub
OPERATION
Run in tool string directly below the rope socket when jarring up. The spring is collapsed and when the hydraulic jars fire, the spring tension is released, accelerating the tool string upwards at a much higher rate of speed. This keeps the energy of the jarring force in the tool string and lessens the force on the line and rope socket.
PRECAUTIONS
Do not place vice jaws or pipe wrenches on the barrel where it can be crushed. Remove cap head screws before attempting disassembly.

BLIND BOX
PURPOSE
Used to deliver downward jarring blows.
DESCRIPTION
For heavy downward jarring to move obstructions downhole, add sufficient stem weight. Choose the correct blind box O.D. to cover the area of obstruction, ensuring the blind box is not too large to pass any restrictions that maybe encountered. When the blind box is ran on the end of a tool string to cut wire from a rope socket of lost wire and tools be sure the O.D. of the blind box will be sufficient.

CENTRALIZER
PURPOSE
To centralize the tool string in large diameter tubing and casings.
DESCRIPTION
The Mechanical Centralizer is made up of six components:
8. Fishneck9. Mandrel10. Spring11. Spring Sub12. Bow Spring13. Bottom Sub
APPLICATION
Generally ran just above the pulling tool, but some applications may require multiple Centralizers higher in the toolstring.
PRECAUTIONS
After each use, inspect bow springs for cracks and wear.
The mandrels are much lighter than full size toolstring, so excessive jarring should be avoided.
Running through profile nipples will score the seal bore, thus damaging the nipple and plugs will not seal.

ROPE SOCKET
PURPOSE
To connect slickline to the tool string.
DESCRIPTION
BT Wedge Rope Socket is made up of 3 components: 1. Body2. Sleeve3. Wedge
OPERATION
Thread line through top of rope socket and sleeve, lay line in groove of wedge and form around radius at bottom of wedge. (care should be taken to form the line around the wedge and not bend or kink the line as this may create a weak spot in line and lead to failure)Once the slickline is formed around the wedge, the sleeve should be slid down over the wire and wedge to hold it in place, the tail of the wire should be trimmed so as not to stick up past top of wedge.

TUBING PUNCH
PURPOSE
To provide a means of achieving well communication between annulus and tubing.
OPERATION
Assemble the Components of the Hydraulic Tubing Punch and attach to the toolstring.Once attached to the toolstring, release safety sleeve, and lower into the wellbore to desired depth, set down on a pre-run collar stop or other firm base. Jar down to shear the shear pin and detonate the charge. The punch is forced through the tubing wall when the firing shell is detonated, gas pressure build up above the piston forces the piston down which displaces the oil in the oil chamber to the punch housing. The oil pressure transmitted to the punch housing shears the punch piston pin and forces the punch piston from the punch housing and through the tubing wall. The outside end of tapered punch being larger in diameter than the inside end allowing the punch to fall outside tubing and clear of the perforator. The hydraulic perforator is designed for three common tubing sizes; 2.375, 2.875 and 3.50 inch tubing. With the use of larger OD sleeves and longer punch piston the 2.375 perforator is converted to 2.875 and 3.50 inch. Two styles of firing pins and shell caps are available which are rim fire or center fire. The style of firing pin must be matched with the charge.

ROLLER STEM
PURPOSE
To ease friction by centering the tool string.
DESCRIPTION
The BT Roller Stem is made up of 4 components: 1. Roller Stem2. Wheel3. Bushing4. Roll PinRoller stem is made up in short sections usually two feet in length with upper and lower thread connections. Slots cut at 45 to one another are cut in the body lengthwise. Rollers are mounted in the slots with the use of a roller shaft placed at 90°. The rollers used have an outside diameter larger than the body of the roller stem. This allows the tool string to have a gliding effect.
APPLICATION
Used in wells with great degrees of deviation, slant wells and wells containing internal coated tubing.
OPERATION
The roller stem is normally placed midway in the tool string. In some applications placement is near the top and bottom of the tool string.
PRECAUTIONS
After each use inspect rollers for cracks, wear or chips.

SAMPLE BAILER
PURPOSE
To obtain sample material from the bottom of the wellbore, or other obstructions caused by sediment, or scaling in wellbore.
COMPONENTS
1. Fishneck2. Barrel3. Ball4. Shoe
DESCRIPTION
The Sample Bailer is operated by jarring down into the debris in wellbore and thus forcing the material upward past the ball into the barrel. The ball has limited travel due to the cross pin through the barrel and typically should relax onto the ball seat after the barrel is filled, thus trapping the sample inside the barrel.

TUBING END LOCATOR
OPERATION
Select the correct finger size and install in the slotted housing.Using a brass shear pin assemble to the tool string. The tool string and tubing end locator are lowered down the well, until just past the tubing bottom.The finger will now rotate out from a compressed position to a horizontal position resting on the shear pin.Raising the tool string until a weight increase appears on the weight indicator, indicates the tubing bottom depth. The tool string is now lowered approximately two meters, and accelerated up quickly, striking the finger on the tubing bottom and shearing the shear pin.The shear pin may also be sheared with the use of hydraulic jars.When ran in conjunction with a sample bailer, a sample from total depth of the well can be obtained.Delivering a few light downward jars sinks the sample bailer into the bottom of the well to catch a sample.

C1 RUNNING TOOL
PURPOSE
To run Baker style “S”, “W”, and “Z”, lock assemblies.
DESCRIPTION
The “C-1” running tool consists of two parts.
1. Body
2. Locating Ring
OPERATION
The “C-1” pinning procedures is done in one of two ways. Pinning the lock assemblies only, the two upper outer series of pin holes are used, pinning under the fishing neck of the lock assembly, brass shear stock is used.
Pinning the “C-1” running tool to the “S” selective lock assemblies will require an “A” shank to retract down facing locks, to avoid the lock assembly hanging up while lowering assembly into the well.
The up facing locks trail enabling them to locate in the nipple profile during upward jarring of the setting sequence.
Pinning to plugs with removable equalizing mandrels, the lock assembly is pinned in the same manner under the fishing neck, except using the lower outer series of pin holes with brass shear stock.
The equalizing mandrel is pinned through an upper center pin hole, or one of the upper outer holes, this pin will be brass depending on the size of the plug being ran.
The “W” and “Z” lock assemblies are pinned in the same manner, being no-go lock assemblies no shanks are required during the normal setting procedures.
To set the lock assembly in the nipple profile lower to the nipple, moderate downward jarring ensures that the lock assembly has landed to the proper depth before upward jarring is administered to set the lock assembly and shear the “C-1” running tool pins.
PRECAUTIONS
Before running check the locator ring size to make sure that it matches the nipple profile when setting selective locking assemblies.
18 | P á g i n a
X RUNNING TOOL
PURPOSE

GR ADAPTER
PURPOSE
Used most commonly for retrieving down hole components, that require downward movement or jarring during pulling sequence.
DESCRIPTION
The ‘GR’ sub consists of four components:
1. Fishneck
2. Shear Sub (* inner core)
3. Core (** pin)
4. Split Collar (*** band)
OPERATION
The ‘GR’ pulling tool is assembled by attaching a ‘GR’ adapter sub to the top of a ‘GS’ pulling tool. The shear pin must be removed from the shear down ‘GS’ pulling tool and a shear pin installed in the ‘GR’ adapter sub.
Shearing the ‘GR’ pulling tool is accomplished by upward jarring. Once the pin is sheared in the ‘GR’ adapter sub, the cylinder on the ‘GS’ is forced upward by the core spring tension releasing the dogs to the retracted position.
Extended core lengths are optional for ‘GS’ portion of the pulling tool for retrieving equipment with an inner locking sleeve.

GS PULLING TOOL
PURPOSE
Manipulation and retrieving of down hole Wireline tools.
DESCRIPTION
Consists of nine components: 1. Fishneck2. Core3. Shear Sub4. Cylinder5. Core Spring6. Spring Retainer7. Dog Spring8. Dog Retainer9. Dogs
OPERATION
Shear pin placement is through top cylinder sub and core. Dogs are contained in the lower end of the cylinder, and held in place by the dog retainer.
Similar to the external pulling tools the core is tapped to accept prongs or core extensions. Shearing of the ‘GS’ pulling tool is accomplished with downward jarring. The core is driven down as the cylinder lands on top of the internal fishing neck body.
Once the pin is sheared the dogs retract up to tapered recess of core. The tension of the core spring holds the dogs retracted, allowing the pulling tool to release from the fish.
’GS’ pulling tools are normally pinned with brass, or mild steel.
PRECAUTIONS
Sand or debris on top of fishneck may hamper the shearing ability in such cases a “GR” may be used.
Care should be taken to inspect the dogs, skirt, and fishneck for damage such as metal, fatigue, cracking, or deformity of the metal.

JDC PULLING TOOL
PURPOSE
To run and retrieve subsurface tools.
DESCRIPTION
BT JDC’s are made up of 8 (*10) components: 1. Fishneck2. Core Cap3. Core4. Core Spring5. Skirt6. Dog Spring7. Dog8. Pawls9. Shear Pin Sub*10. Shear Pin Cover*
OPERATION
Used when there is a need to jar down to shear off of a subsurface tool and/or fish when a jar up tool is not desired.
Used for setting tubing stops or any other tools where one must jar down to set.
The core may be easily changed in the field to allow for a deeper or shallower reach depending on application.
The BT JDC pulling tool is able to be turned into a BT JUC by simply changing the fishneck and removing the core cap.
PRECAUTIONS
Ensure the proper core is installed so as the tool can properly be sheared, the improper core may result in the inability to release the subsurface tool and/or fish.
Care should be taken to inspect the dogs, skirt, and fishneck for damage such as metal . fatigue, cracking , or deformity of the metal.
ACT JU (Jar Up) Pulling Tools are used to shear and release tools and are available with C - S Core options.JD (Jar Down) Pulling Tools are also used to shear and release tools and are available with C - S - L Core options.

SHIFTING TOOL D2
DESCRIPTION
The “D-2” shifting tool is designed to shift Baker style “L” sliding sleeves. Made up of several components, the main parts of the “D-2” shifting tool are:
1. Fishneck2. Mandrel3. Collet4. Connecting Adjuster5. Control Sleeve6. Nut7. Spring8. Retractor9. Retaining Sleeve10. Dog11. Dog Retainer12. Dog Spring13. Key14. Thread Protector
Collets come in different OD measurements, each sleeve ID will require a corresponding collet with a larger OD.
The purpose of the collet is to locate the sleeve desired to be shifted, the tool can then be extended allowing the spring loaded dogs to move outward latching the inner sleeve for shifting.
The collet design allows locating and shifting any desired sleeve in a completion with two or more sleeves.
The selective collet feature includes both the opening and closing “L” sleeves. The tool requires a specific distance from the square face of the shifting dog to the collet locating profile. This measurement is done with the tool in the retracted position and allows for the shifting tool to disengage the sleeve when the shifting sequence is complete.
Although the shifting tool can be deliberately released three steel shear pins are incorporated at the base of the shifting dogs allowing for a safety release feature.

WIRELINE GRABS
PURPOSE
Fishing slickline or cable lost down well bore.
DESCRIPTION
The wireline grab has 3 components: Fishneck
1. Locator Ring
2. Body
3. The wireline grab consists of a hollow housing below the top sub.
Either two or three long slots are machined to the bottom of the housing to form the prongs. There are barbs attached to the inside of the prongs pointing upward. The bottom end of the prongs are tapered to guide the wire to the inside of the grab and to conform to the I.D. of the tubing.
The number of prongs will vary with the size of the tubing to maintain the strength of the grab. Smaller sizes of grabs will have only two prongs, while larger sizes may have three or more.
The wireline grab’s O.D. usually corresponds to the drift diameter of the tubing, but can be constructed to a desired choice of O.D.
Threaded rings may also be added to top of grabs to get desired O.D. so as not to allow wire or debris past the wiregrab.

R LOCK
PURPOSE
To locate and lock a variety of subsurface controls in the desired corresponding nipple profiles.
DESCRIPTION
The “R” lock mandrels have internal fishing necks, their components are:1. Fish Neck2. Expander Sleeve3. Packing Mandrel4. Key Retainer Sleeve5. Key Springs6. Keys7. Packing Assembly.
The “R” lock mandrels with the flow control components are designed for the “R” seating nipples installed in heavy weight tubing.
These lock mandrels similar in design are selective, this is made possible by their running tools.
The lock mandrels maybe installed in any one of multiple seating nipples installed in the tubing string of comparable size.
Once the desired nipple has been located in the tubing string these mandrels are mechanically locked. This is done by driving the expander sleeve behind the keys, holding the mandrel in a locked position.
OPERATION
The “R” lock mandrels are ran selective, or can be ran in the non selective position when setting in the upper “R” profile in the tubing completion string.
Both the running positions are built into the running tool which has a set of locating dogs to selectively run and set the lock mandrels in the lower nipples in the string.
The running tool is changed to a non selective position once the desired selective nipple has been located. This is done by lowering the running tool with the lock mandrel through the nipple profile and then pulling back up through. The “R” running tool procedures are explained in the “X” running tool operation in the running tools section.

X LOCK
PURPOSE
To locate and lock a variety of subsurface controls in the desired corresponding nipple profiles.
DESCRIPTION
The “X” lock mandrels have internal fishing necks, their components are:1. Fish Neck2. Expander Sleeve3. Key Retainer Sleeve4. Packing Mandrel5. Key Springs6. Keys7. Packing Assembly.
The “X” lock mandrels with the flow control components are designed for the “X” seating nipples installed in standard weight tubing. These lock mandrels similar in design are selective, this is made possible by their running tools.
The lock mandrels maybe installed in any one of multiple seating nipples installed in the tubing string of comparable size.
Once the desired nipple has been located in the tubing string these mandrels are mechanically locked. This is done by driving the expander sleeve behind the keys, holding the mandrel in a locked position.
Running tool required is “X”
Pulling tool required is “GS” or “GR”.
OPERATION
The “X” lock mandrels are ran selective, or can be ran in the non selective position when setting in the upper “X” profile in the tubing completion string.
Both the running positions are built into the running tool which has a set of locating dogs to selectively run and set the lock mandrels in the lower nipples in the string.
The running tool is changed to a non selective position once the desired selective nipple has been located. This is done by lowering the running tool with the lock mandrel through the

S LOCK
PURPOSE
To selectively lock subsurface controls in compatible “F” seating nipples.
DESCRIPTION
The “S” lock assemblies have an external fishing neck and consist of:
1. Lock Mandrel
2. Four Lock Dogs
3. Lock Springs
4. Pins
The locks are fitted and pinned in the mandrel with two locks facing up to prevent upward movement and two locks facing down to prevent downward movement once the lock assembly is locked into place in the “F” seating nipple.
The “S” lock assemblies are made selective by two components, they are graduated nipple seal bore sizes and the running tool locator ring sizes. The “S” lock assembly is ran with the “C-1” running tool complete with locator ring and model “A” shank.
The shank is required if the lock assembly is not equipped with a removable equalizing mandrel in the subsurface control.
The model “A” shank when threaded into the running tool and pinned to the “S” lock assembly retracts the down facing locks for running in the well. Pulled with a “JUC” or “JDC” pulling tool and model “A” swivel probe to unlock the up facing locks.
OPERATION
The “S” lock assembly with the subsurface control is pinned to the “C-1” running tool with appropriate locator ring. The “C-1” is attached to the tool string and lowered in the well to just above the desired seating nipple, the tool string weight is now taken.
The lock assembly is now set in the seating nipple profile with moderate downward jarring, an upward strain will indicate the lock assembly with the sub surface control is locked in the nipple. Upward jarring will shear therunning tool pins, releasing the “C-1” running tool from the lock assembly.
48 | P á g i n a
Once the shearing sequence is done the “S” lock assembly will be retained in the seating nipple profile with the four locks. When running the up facing locks are trailing and during pulling the down facing locks are trailing.
PRECAUTIONS
Choosing the correct locator ring for the “C-1” running tool is important to eliminate the possibilities of the lock assembly and the subsurface control being located and set in the wrong profile in the tubing string.Nominal Size

W LOCK
PURPOSE
To offer a positive locating sequence for sub surface controls in selective “F” nipple profiles.
DESCRIPTION
The “W” top no-go lock assemblies have an external fishing neck and consist of:
1. Lock Mandrel
2. Two Lock Dogs
3. Lock Springs
4. Pins
The “W” lock assemblies have a larger OD dimension near the top of the lock mandrel which no-go’s on top of the nipple profile sealing bore preventing downward movement when locked in the nipple profile.
The two locks are fitted and pinned in the body of the lock mandrel facing up to prevent upward movement of the lock assembly when locked into the nipple profile.
The “W” lock assemblies are ran in the “F” profile seating nipples having a seal bore dimension smaller than the lock assembly no-go OD dimension.
Ran with a “C-1” running tool.
Pulled with a “JUC” or “JDC” pulling tool and the model “B” probe to disengage the locks.
OPERATION
The “W” lock assembly with subsurface control is appropriately pinned to the“C-1” running tool, no shanks or locator rings are required for “C-1” running tool.
The “C-1” running tool with the “W” lock assembly and the subsurface control is attached to the tool string and lowered to the nipple profile, taking the tool string weighs above nipple depth.
Downward jarring sets the “W” lock assembly in the seating nipple profile.
Upward strain ensures the lock assembly is set in the seating nipple profile, upward jarring now shears the pins in the “C-1” running tool.
50 | P á g i n a
The “W” lock assembly is ran with the up facing locks trailing.
PRECAUTIONS
Be sure the “W” lock assembly no-go OD is larger than the seal bore size of the desired seating nipple it is to be set in. This prevents the loss of the lock assembly and accessory out of the tubing string into the casing, should there be no more nipples with a small enough ID for the “W” lock no-go to locate in.

Z LOCK
PURPOSE
Locking subsurface controls in Model “R” bottom no-go seating nipples.
dEScripTion
The “Z” lock assemblies have an external fishing neck and consist of;
1. Lock Mandrel
2. Two Lock Dogs
3. Lock Springs
4. Pins
The “Z” lock in conjunction with the subsurface control accessory sets in the model “R” bottom no-go seating nipples.
The no-go for landing in the “R” bottom no-go nipples is located on the packing mandrel of the subsurface control screwed to the “Z” lock assembly.
The two locks are fitted and pinned in the body of the “Z” lock assembly facing up, to prevent upward movement of the lock assembly when locked into the seating nipple profile.
Ran with a “C-1” running tool.
Pulled with a “JUC” or “JDC” pulling tool and the model “B” probe to disengage the locks.
OPERATION
The “Z” lock assembly with subsurface control is ran in the same sequence as the “W” lock assembly.
The “Z” lock assembly with the attached accessory can be ran and set in the type “R” bottom no-go seating nipple only.
