1. A system for plugging a wellbore extending from the surface and into a subterranean earthen formation, the system comprising:
a plug comprising an annular sealing element and having an initial configuration configured to permit fluid flow around the plug in the wellbore and a set configuration configured to plug the wellbore whereby fluid flow around the plug in the wellbore is restricted;
a setting tool configured to couple with the plug and comprising an energetic element received in a combustion compartment of the setting tool, the setting tool configured to shift the plug from the initial configuration to the set configuration in response to ignition of the energetic element; and
a setting tool initiator comprising an addressable igniter switch and an igniter, wherein the igniter is configured to ignite the energetic element of the setting tool from a location that is external the combustion compartment in response to the igniter switch receiving a firing signal addressed to the igniter switch;
wherein the igniter switch has an operational state in which the igniter switch is configured to receive electrical signals from the surface and an inoperable state in which the igniter switch is not configured receive electrical signals from the surface, and wherein the setting tool initiator is configured to shift the igniter switch from the operational state to the inoperable state in response to the ignition of the igniter.
