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.

Downhole setting assembly with switch module

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.

Initiator system providing set confirmation from plug setting tool in downhole well

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.
