Abstract: 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.

Abstract: A setting tool includes a housing having an initiator compartment to receive an initiator for initiating combustion of a combustible element, a combustion compartment to receive the combustible element, and a switch compartment to at least partially receive a switch circuit for activating the initiator, a piston configured to impart a setting force against the plug in response to combustion of the combustible element, and an interrupt flowpath configured to connect at least one of the combustion compartment and the initiator compartment with the switch compartment whereby combustion products that may be created in the initiator compartment or combustion compartment would be circulated from the at least one of the combustion compartment and the initiator compartment to the switch compartment to disconnect the switch circuit in response to the activation of the initiator charge.

Abstract: A plug for sealing a wellbore includes a mandrel extending between an uphole end defining an uphole end of the plug, and a downhole end opposite the uphole end of the mandrel, a slip assembly extending around the mandrel and including a plurality of arcuate slip segments, a nose coupled to the downhole end of the mandrel and defining a downhole end of the plug, wherein the nose includes an uphole end coupled to the downhole end of the mandrel and a downhole end opposite the uphole end of the nose and defining a downhole end of the plug, and a packer extending around the mandrel and including a first configuration configured to permit fluid flow across the plug when the plug is received in the wellbore, and a second configuration configured to seal the wellbore when the plug is positioned in the wellbore.

Abstract: A plug for sealing a wellbore includes a mandrel including a body having a longitudinal first end, a longitudinal second end opposite the first end, and an outer surface, wherein a plurality of ratchet teeth are positioned on the outer surface and formed of a fiber reinforced composite material, an annular seal positioned on the outer surface of the mandrel, wherein the seal includes a first longitudinal end and a second longitudinal end opposite the first end; and a body lock ring assembly positioned on the outer surface of the mandrel and located between the first end of the mandrel and the seal, wherein the body lock ring assembly includes a plurality of circumferentially spaced arcuate lock ring segments surrounding the mandrel, wherein an inner surface of each lock ring segment includes a plurality of ratchet teeth configured to matingly engage the ratchet teeth of the mandrel.
