Definitions
- the present invention relates generally to a release device that may be used with downhole setting tools.
- the release device of the present disclosure deforms to provide a releasable detachment mechanism for a setting tool used to set a downhole tool, such as a Python Frac Plug from BJ Services Company of Houston, Texas.
- a deformable release device may provide a releasable detachment to any customary setting tool used to set a downhole packer-type device, for example.
- customary setting tools include electric line, hydraulic, hydrostatic, and mechanical setting tools or other setting tool designs that use a combination of these methods for actuating a packer-type device in a subterranean well.
- adapter kits are intermediate devices, inserted between the setting tool and the packer, which adapt the connection between the setting tool and the packer and allow for the detachment of the two after the packer is set.
- Many different methods can be used to convey the setting tool, adapter kit, and packer device into a wellbore, to set the packer, and to detach the setting tool and adapter kit from the packer.
- One method may use jointed pipe, whereas other methods may use coiled tubing, wireline, or slick line, for example.
- the method selected to run and set the packer depends on a number of variables, such as time constraints, costs, deviation of the wellbore, or which part of the servicing cycle the well is in. Due to the number of methods to run and set a packer, many different adapter kits are utilized in the oil and gas industry, such as mechanical, hydraulic, or wireline adapter kits.
- a wireline adapter kit (“WLAK”)
- WLAK wireline adapter kit
- An adapter kit used with a mechanical setting tool might utilize a simple coarse screw thread, such as an acme thread running around the perimeter of the lower end of the adapter kit, to connect the setting tool to the packer.
- the packer has mating threads to engage the threads of the adapter kit.
- the relatively simple coarse screw thread also allows the setting tool to be rotationally disengaged from the packer device once the packer device has been set. However, in some situations, such as in horizontal wells, it can be relatively difficult to rotate the setting tool and adapter kit.
- Another means for disengaging the adapter kit from the packer device is a design that includes a portion of the connection adapted to release when subjected to a predetermined mechanical load. Designs that release under a predetermined mechanical load may be designed to release either automatically or manually. An automatic release occurs during the setting sequence, once the packer/adapter kit connection is subjected to a load above a predetermined limit. A manual release requires the application of the predetermined load to the adapter kit after the setting sequence. Examples of a manual release are rotational releases, as described above, or merely pulling tension into the adapter kit.
- One type of adapter kit that automatically releases under a mechanical load is a wireline adapter kit.
- the release of a wireline setting tool adapter kit may be accomplished by mechanically failing a component of the adapter kit such as a "release stud," shear screw(s), a shear ring, or shear pin(s) with a known amount of force.
- Such components fail with the application of a predetermined amount of a tensile or axial force.
- the Baker Model B WLAK is an example of an adapter kit that uses a device, specifically a release stud, that automatically fails with a known axial force, which in one size is approximately 33,000 lbs, when applied to the adapter kit.
- shear pins or other mechanically failing devices
- a hole for the insertion of a shear screw or shear pin is typically drilled in a component, such as the packer.
- the drilling of a hole into the packer may weaken the overall strength of the packer, especially if the hole is drilled into a brittle material such as cast iron, possibly leading to premature failure of the component.
- Other adapter kits and mechanical release devices are generally rather complex in design. This complexity increases the manufacturing and assembly costs for. the system.
- mechanical release devices that release by failing a mechanical component, such as shear screws, leave remnants of those components in the wellbore, as discussed above.
- a build up of these remnants in the wellbore may require the milling out or drilling out of the wellbore, which adds to the cost of production and leads to delays in production from the well. iooni

- a deformable release device having an opening may be located substantially at the bottom of a downhole tool mandrel, and may be located between a release stinger and a plunger.
- the plunger When a requisite upward axial force is applied to the release stinger, the plunger may be pulled through the deformable release device deforming the opening of the deformable release device.
- the force required for the plunger to pull through the deformable release device can be predetermined. The force required to deform the deformable release device is resisted by the downhole tool, and is thereby converted into the setting force.
- the deformable release device may enable the automatic disengagement of the setting tool from the plug. Specifically, once the requisite axial upward force is applied to the release stinger, the plunger is pulled through the deformable release device.

- FIG. 1 shows a wireline pressure setting assembly 10, specifically a 10 E-4 wireline pressure assembly as commercially offered by Baker Hughes, Inc. of 3900 Essex Lane, Houston, Texas. Although shown in use with a BJ Services Company wireline adapter kit 20 and a wireline pressure setting assembly 10 from Baker Hughes, Inc., the deformable release device 30 of the present disclosure may be used with various adapter kits and setting tools as would be recognized by one of ordinary skill in the art.
- the wireline adapter kit 20 of Figure .1 includes an adapter sleeve 40 and a release stinger 50.
- the adapter sleeve 40 is threaded onto the wireline pressure setting assembly 10 and extends down to the packer assembly 70, such as a Python Frac Plug Assembly offered by BJ Services Company of Houston, Texas.
- One end of the release stinger 50 is threaded onto the downhole end of the wireline pressure setting assembly 10.
- a torsional spring 60 prevents the release stinger 50 from accidentally unthreading from the wireline pressure setting assembly 10 due to vibrations or load cycling exerted on the release stinger 50.
- a plunger 80 is threaded onto the downhole end of the release stringer 50.
- a coiled spring 90 prevents the plunger 80 from unintentionally unthreading from the release stinger 50 due to vibrations or cyclic loading.
- a bumper 100 is attached to the end of the plunger 80.
- the packer assembly 70 includes an upper cap 71, an upper slip 72, an upper cone 73, an elastomeric packing element 74, a lower cone 75, a lower slip 76, a lower cap 77, and a mandrel 78.
- the mandrel 78 which is wrapped around a brass core 79, provides the general support for each of the components of the packer assembly 70.
- the present invention is adapted to be used with various types of packer assemblies. For the purposes of illustration, a packer assembly 70 will be described herein. However, other packer assemblies could be set and used with the release device of this disclosure as would be appreciated by one of ordinary skill in the art.
- a downward force is applied to the packer assembly 70 causing the upper slip 72 to move up the upper cone 73.
- the tapered shape of the upper cone 73 moves the upper slip 72 outward and the upper slip 72 engages the casing wall, thus locking the packer assembly 70 in place within the well.
- the upward force moves the lower portion of the packer assembly 70 (i.e., lower cap 77, lower cone 75, and lower slip 76) upward toward the upper portion of the packer assembly 70. Because the upper portion is anchored against the wall of the casing, the movement of the lower portion axial Iy compresses the elastomeric packing element 74.
- the tapered shape of the lower cone 75 moves the lower slip 76 outward until it engages the well casing, thus locking the lower portion of the packer assembly 70 in place within the well.
- the downward force applied to set the packer assembly 70 causes an upward force on the release stinger 50, which is held in place by the deformable release device 30 resting on the protruding section 83 of the plunger 80.
- the plunger 80 is attached to the lower end of the release stinger 50.
- a deformable release device 30 retains the packer assembly 70 on the release stinger 50.
- the deformable release device 30 contacts the protruding section 83 of the plunger 80, which is attached to the lower end of the release stinger 50.
- Pins 31 secure the deformable release device 30 to the mandrel 78 of the packer assembly 70.
- the force applied by the setting tool causes an upward force on the release stinger 50.
- the release stinger 50 is held in place by the deformable release device until the upward force becomes greater than the force required to deform the deformable release device.
- the plunger 80 is pulled through the deformable release device 30, which deforms the deformable release device 30.
- the deformation of the release device 30 allows for the automatic release of the setting tool 10 and adapter kit 20 without any debris failing into the wellbore.
- the deformable release device 30 is shown in use with a wireline adapter kit 20 and a packer assembly 70, the deformable release device may be used with various adapter kits and plugs or packers or various downhole tool assemblies as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure.
- 10043 As shown in Figure 1, a bumper 100 may be attached to the bottom of the plunger 80.
- the purpose of the bumper 100 is to minimize damage to the downhole components after the plunger 80 has been pulled through the deformable release device 30. Once the plunger 80 is pulled through the deformable release device 30 there may be a tendency for the assembly of the setting tool 10 and the wireline adapter kit 20 to bounce up and down due to the large force that has been exerted to set the plug assembly and pull the plunger through the deformable release device. The force was previously countered by the deformable release device 30, but once the release device 30 deforms the force may cause the wireline adapter kit 20 to bounce up and down.
- the bumper 100 may be comprised of nylon to minimize damage to the downhole components that the bottom of the assembly may strike.
- the bumper could be comprised of any material that would minimize damage due to impact as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure.

- the outer perimeter of the entire downhole portion 82 of plunger 80 may be larger than the opening in the deformable release device 30.
- the downhole portion 82 of the plunger includes a structure 84 adapted to retain a bumper 100.
- the protruding portion 83 of the plunger 80 may have a leading edge 85 adapted to deform the deformable release device 30.
- the leading edge 85 may extend upward from the upper portion 81 of the plunger at 100 degrees.
- increasing the angle between the leading edge 85 and the upper portion 81 would decrease the initial deformation by the plunger.
- the outer diameter of the plunger 80, at is greatest width, may determine whether the plunger deforms the deformable release device 30 and to what extent the release device 30 is deformed.
- the trailing edge 86 of the protruding portion 83 may be tapered to enable passage of the plunger 80 through the deformable release device 30 after deformation.
- the trailing edge 86 may be tapered away from the protrusion at 135 degrees.
- the geometry depicted in Figure 2 is only one embodiment of a plunger. However, a plunger of various geometries may be used to deform a deformable release device to release a downhole tool as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure.
- Figure 3A shows a cross-section of a deformable release device 30 and plunger 80 of one embodiment of the present disclosure prior to the deformation of the deformable release device 30.
- the deformable release device 30 may be circular in shape and fairly flat with a circular opening centrally located.
- the deformable release device 30 is retained against the mandrel 78 by retaining pins 31.
- the plunger 80 may be circular with an uphole portion 81 that is connected to the release stinger 50 and that is sized to fit through a central opening of the deformable release device 30.
- the remaining portion 82 of the plunger 80 may have an outer diameter larger than the central opening of the deformable release device 30.
- the plunger 80 When an upward force large enough to deform the release device 30 is applied to the plunger 80, the plunger is pulled through the deformable release device 30.
- the lower portion 82 of the plunger 80 deforms the deformable release device 30 allowing for the release of the adapter kit - and setting tool - from the plug.
- the force required to deform the deformable release device 30 can be set by modifying the material, size, and shape of the deformable release device 30 as well as the plunger 80.
- the use of a plunger 80 and deformable release device 30 decreases the manufacturing costs of adapter kits and downhole tools as compared to using other mechanically releasing devices such as shear pins and shear screws.
- Figure 3B shows a cross-section of a deformable release device 30 and plunger 80 of one embodiment of the present disclosure prior to the deformation of the deformable release device 30.
- the deformable release device 30 may be circular in shape and fairly flat with a circular opening centrally located.
- the deformable release device 30 is retained against the mandrel 78 by retaining pins 31.

- the plunger 80 may have a protruding portion 83 having an outer diameter larger than the central opening of the deformable release device 30.
- Figures 4A-4C show an adapter kit and plug assembly using a deformable release device being run into the wellbore, setting the plug, and removing the adapter kit from the well bore.
- Figure 4A shows a running plug assembly attached to a setting tool via an adapter kit into a well bore. As the plug is conveyed into the wellbore, the deformable release device 30 retains the plug assembly on the adapter kit 20.
- the setting tool 10 applies a downward force 110 to the plug assembly 70 through the adapter sleeve 40.
- the downward force 110 applied to the plug assembly sets the slips 72, 76 against the well casing and expands the elastomeric packing elements 74 against the well casing creating a seal.
- Figure 4B shows the plug assembly being set in the bore as indicated by the expanded elastomeric packing elements 74 as well as the slips 72, 76 being set against the well casing.
- the plunger 80 shown in Figure 4B has not yet been pulled through the deformabie release device 30.
- the application of a downward force 110 through the adapter sleeve 40 also causes an upward force 120 on the release stinger 50 and attached plunger 80.
- the deformabie release device 30 counters the upward force 120 and retains the release stinger 50 and plunger 80 in place relative to the plug assembly.
- the downward force 110 continues to increase, which also increase the upward force 120 on the release stinger 50 and plunger 80.
- a deformabie release device 30 retains the plug assembly 70 on the release stinger 50. Pins 31 secure the deformabie release device 30 to the mandrel 78 of the plug assembly 70.
- the force applied by the setting tool causes an upward force on the release stinger 50.
- the release stinger 50 is held in place by the deformabie release device 30 until the upward force becomes greater than the force required to deform the deformabie release device 30. Once the force exceeds this amount, the plunger 80 is pulled through the deformabie release device 30, which deforms the deformabie release device 30.
- the deformation of the release device 30 allows for the automatic release of the adapter kit 20 — and setting tool 10 - while minimizing the risk of debris from the release left in the wellbore.
- FIG. 4C shows plug assembly 70 set against the well casing and the deformabie release device 30 after the adapter kit 20 - and downhole tool 10- has been released by the deformabie release device 30.
- the plunger 80 has been pulled through the deformabie release device 30 deforming in against the mandrel 78 of the plug assembly 70.
- the deformation of the deformabie release device allows for the release of the adapter kit 20 from the plug assembly 70.
- a valve 130 such as a flapper valve, may close off the axial passage within the mandrel 78. This disclosure reduces the likelihood that the release of an adapter kit will create debris in the wellbore.
- FIG. 5 shows the top view of one embodiment of the deformabie release device 30.
- the deformabie release device 30 is substantially circular in cross-section with a circular central opening 33.
- Figures 6 and 7 show alternative embodiments of the deformabie release device 30 have a central opening 33 with slots 34 cut into the opening.
- the addition and location of the slots 34 allows for the better control of how the plunger 80 deforms the deformable release device 30.
- the addition of slots 34 in the deformable release device 30 also provides that the release device 30 may deform at a lower force.
- deformable release device 30 of Figure 7 may deform at a lower force than the embodiment of Figure 6, if both are comprised of the same material.
- Figures 8A-8F and 9A-9J illustrate a number of various embodiments of the deformable release device of the present disclosure.
- the size, shape, and material of the deformable release device may be modified to change the force required to deform the deformable release device, thus releasing the adapter kit. If the deformable release device is used with a packer assembly, the deformation force needs to be greater than the setting force required to set packer as would be appreciated by one of ordinary skill in the art.
- the necessary deformation force may range between 27,900 lbs. and 7,500 lbs for the embodiments shown in Figures 8A— 8F.
- the amount of force required to deform the release device can be predetermined by the material used as well as the overall dimensions and shape of the deformable release device. For example, the addition of slots, tapering the device, or enlarging the opening decreases the requisite deformation force as would be appreciated by one of ordinary skill in the art. l oose) Typically, a force of 50,000 lbs. is required to set a plug having an outer diameter of 5- 1/2 inches. A force of 30,000 — 33,000 lbs. is generally required to set a plug with an outer diameter of 4-1/2 inches. Plugs having an outer diameter of 2-7/8 inches or less typically require a setting force of 9,000 — 11,000 lbs.
- Figures 8A— 8F and 9A— 9J are only examples of some of the shapes and dimensions of the deformable release device.
- the required deformation force to release an adapter kit may be may be varied depending on the material of the deformable release device as well as the configuration of the deformable release device and the plunger. ioo57
- various embodiments have been shown and described, the invention is not so limited and will be understood to include all such modifications and variations as would be apparent to one skilled in the art.
