Novel Device and Methods for Firing Perforating Guns

Abstract

A perforating gun train for perforating two or more zones of interest includes two or more gun sets made up of guns, one or more activators, and other associated equipment. An illustrative apparatus may include a first perforating gun; an activator responsive to the firing of the first perforating gun and a fuse element detonated by the activator; and a second perforating gun that is fired by the fuse element. An illustrative method for perforating a subterranean formation may include forming a perforating gun train using at least a first perforating gun and a second perforating gun; and energetically coupling the first perforating gun and the second perforating gun with an activator.

1 . An apparatus for perforating a subterranean formation, comprising:
 a first perforating gun that is configured to perforate the subterranean formation;   an activator responsive to the firing of the first perforating gun;   a fuse element detonated by the activator;   a second perforating gun that is configured to perforate the subterranean formation, the second perforating gun having a detonator activated by the fuse element.
