A method for redressing a setting tool for actuating a plug in a subterranean wellbore includes recovering the setting tool from the wellbore, the setting tool including a housing with a throughbore therein, a piston arranged for axial movement within the throughbore, a combustible element, and an exhaust diffuser configured to redirect a flow of combustion products generated in response to ignition of the combustible element, removing the piston from the throughbore of the housing, removing the exhaust diffuser from the housing, cleaning the piston and the housing, and reinstalling the piston into the housing of the setting tool with at least one of the exhaust diffuser and a replacement exhaust diffuser for subsequent use of the setting tool in a wellbore.

A system for plugging a wellbore includes a plug including an annular sealing element, a setting tool configured to couple with the plug and including an energetic element, the setting tool configured to shift the plug from an initial configuration to a set configuration in response to ignition of the energetic element, and a setting tool initiator including an addressable igniter switch and an igniter, wherein the igniter is configured to ignite the energetic element of the setting tool in response to the igniter switch receiving a firing signal addressed to the igniter switch, and wherein the setting tool initiator is configured to shift the igniter switch from an operational state to an inoperable state in response to the ignition of the igniter.

A frac plug is disclosed that is used for isolating a lower portion of a wellbore from an upper portion to enable a fracking process on newly created perforations in casing or liner pipe where the frac plug is particularly designed rapid drill out after all the fracking operations have been completed. The frac plug includes arrangements for holding the polymer or rubber element from rotation as the plug is being drilled. One arrangement includes pins that lock the polymer element to the bottom cone. In another, the polymer element is simply bonded by adhesive to the faceted cone. The facets on the cone prevent the cone from rotating in the wellbore by being pressed against the flat bottom slip segments that remain locked to the casing or liner pipe.

Hybrid dissolvable plug with improved drillability

A system for setting a plug in a wellbore includes a setting tool configured, upon activation, to displace the shift the plug in the wellbore from a run-in configuration permitting fluid flow within the wellbore around the plug to a set configuration restricting fluid flow in the wellbore around the plug, an initiator including an igniter switch and an igniter assembly including an igniter energetic element, the initiator including a signal interrupter configured to shift automatically from a first state in which signal communication is provided through the signal interrupter between the igniter switch and the igniter assembly to a second state in which signal communication is restricted through the signal interrupter between the igniter switch and the igniter assembly in response to exposing the initiator to a predefined toolstring condition and whereby a surface indication is provided of the shifting of the plug to the set configuration.

A self-orienting perforating gun includes an outer housing having a throughbore, a charge carrier positioned in the throughbore of the outer housing, a hub secured directly or indirectly to the outer housing, a bearing secured to each carrier end of the charge carrier wherein the bearing overlies the hub to provide a rotatable relationship between the hub and the charge carrier about a rotational axis within the outer housing, and an eccentric weight coupled to the charge carrier applying an off-axis orienting force to the charge carrier for urging the charge carrier to rotate about the rotational axis toward a predefined orientation relative to the direction of gravity.

A perforating gun system includes an outer housing, a charge carrier assembly slidably receivable in the outer housing, wherein the charge carrier assembly includes a charge carrier having a central axis, a first endplate coupled to a first end of the charge carrier, and a second endplate coupled to a second end of the charge carrier, and an annular initiator assembly connectable to the charge carrier assembly, wherein the initiator assembly has a central opening whereby a central axis of the initiator assembly extends centrally through the central opening and parallel with the central axis of the charge carrier, wherein the initiator assembly is configured to detonate a detonator of the perforating gun system in response to receiving a firing signal.

A release tool for connecting a workstring to a toolstring. The release tool will be used for contingency if the toolstring gets stuck downhole and hopefully rarely would be actuated. In the present disclosure, the release tool is not broken or destroyed, but is simply disconnected into two parts using the propellent of a low explosive combustion element. This element produces gasses that drive the disconnecting process. The gasses are directed to press a tubular piston to translate from a first position where a wedging portion of the tubular piston is inside a lock ring bracing the lock ring in a locking configuration to a second position where the wedging portion is out of contact with the lock ring. The lock ring is then able to slip free from one or more locking grooves releasing the upper portion of the release tool from the lower.

A perforating gun deployable in a wellbore includes an outer housing included of a generally tubular wall structure having a pair of opposed longitudinal ends and a central passage extending between the pair of longitudinal ends, a charge carrier assembly received in the central passage of the outer housing and including a tubular charge carrier having a pair of opposed longitudinal ends and at least one radially oriented receptacle configured to receive a combustive shaped charge, an initiator assembly, the initiator assembly including a detonator and an electrical switch configured to detonate the detonator in response to receiving a firing signal, and an electrical connector positioned in the central passage of the outer housing and electrically connected to the initiator assembly, the electrical connector including an electrical contact including a frangible conductor rod, the frangible conductor rod having a shear strength of 1,500 pound-force (Ibf) or less.

Frangible electrical contact for a perforating gun system

A method for producing a tandem sub for a perforating gun system includes positioning an electrically conductive signal bar in a central passage of a tubular housing of the tandem sub, and injecting a mold material into an annulus formed between an outer surface of the signal bar and an inner surface of the tubular housing that sealably adheres to both the signal bar and the tubular housing.

Systems, methods, and computer-readable storage devices for providing directions haptically such that sight and hearing can continue unimpeded. In one exemplary embodiment, a wearable device (such as earphones, ear rings, gloves, glasses, or other wearable objects) configured as disclosed herein receives directions to an intended destination for a user, the directions comprising a movement action and a distance to the movement action. The wearable device has multiple haptic output units and generates, through one of those units, a haptic output based on the directions. This allows the user to receive the directions through touch rather than looking at their mobile device or from audio.

System and method for providing directions haptically

Threaded pin made of a starting material, wherein the threaded pin comprises a base, a tip portion, which is spaced apart from the base in the direction of a longitudinal axis of the threaded pin, wherein the tip portion comprises a bridge portion, and a first side wall with an outer profile, said first side wall extending from the bridge portion to a first base part, and a second side wall with an outer profile, said second side wall extending from the bridge portion to a second base part, wherein the first side wall is formed from a different part of the starting material to the second side wall and the first base part is formed from a different part of the starting material to the second base part, wherein part of the first part is in engagement with part of the second base part, and/or part of the first base part is connected to part of the second base part, wherein, as an alternative or in addition, part of the first side wall is in engagement with part of the second side wall, and/or, in addition, part of the first side wall is connected to part of the second side wall.
