A tool string includes a perforating gun, a first electrical connector defining a receptacle and includes a first electrical contact positioned in the receptacle, and a sub including a sub housing including first end, a second end opposite the first end, and a central passage extending between the first end and the second end, and a bulkhead connector positionable in the central passage to form a pressure barrier along the central passage, the bulkhead connector including an outer housing defining a radially outer periphery of the bulkhead connector, and a second electrical contact positioned along the outer periphery of the bulkhead connector and configured to establish radially directed electrical contact with the first electrical contact of the first electrical connector irrespective of the angular orientation of the second electrical contact relative to the first electrical contact.

A perforating gun system includes a cylindrical outer housing, a charge carrier assembly receivable in the outer housing, wherein the charge carrier assembly includes a charge carrier defining an interior configured to at least partially receive one or more shaped charges, 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 wherein the first endplate defines a switch receptacle for at least partially receiving an electrical switch and a detonator receptacle for receiving a detonator such that the detonator is configured to detonate the one or more shaped charges in response to receiving a firing signal from the electrical switch.

A swivel assembly includes a first member having a first throughbore, a second member having a second throughbore, a flexible joint coupled between the first member and the second member that permits at least one of the first member and the second member to rotate an unlimited number of rotations relative to the other and that also connects the first throughbore and the second throughbore such that an electrical signal pathway for receiving an electrical signal conductor is formed that extends continuously through the flexible joint and between the first throughbore and the second throughbore, and a pressure bulkhead positioned along the electrical signal pathway that divides the electrical signal pathway into a pressure exposed zone that is exposed to external pressure from the surrounding environment and a pressure isolated zone that is isolated from the external pressure.

A plug deployable into a wellbore having a casing string includes a sealing element including an outer sealing surface configured to extend outwardly from a central axis of the plug and sealingly press against a casing string when the plug is in the second configuration, and a slip including at least one slip body having a peripheral outer face oriented to face away from the central axis and towards the casing string, and one or more engagement members located on the outer face of the slip body wherein the one or more engagement members are configured to bite into the casing string when the plug is in the second configuration, wherein at least 40% of a total volume of the plug is formed from corrosion-selected materials and at least 30% of the total volume of the plug is formed from corrosion-resistant materials.

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 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.
