Abstract: An apparatus for selectively activating a downhole tool by using a Shockwave generated by a detonator assembly may include an outer housing having a bore and an inner housing disposed in the bore of the outer housing. The inner housing may include a chamber having at least one canted surface, an inlet communicating with the chamber and being positioned between the chamber and the detonator assembly, an outlet communicating with the chamber and being positioned between the chamber and the downhole tool, and an energy blocker disposed in the chamber and being freely movable in the chamber as the inner housing changes orientation relative to a vertical datum. The energy blocker axially aligns with the inlet and the outlet when the inner housing is angularly offset less than a specified amount relative to a vertical datum.

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.

Abstract: An interrupter for use with a wellbore tool may include a housing having an interior and a fusible body disposed in the housing interior. The fusible body may be solid below a specified temperature and liquid above the specified temperature. The fusible body communicates a first high-order detonation to a detonator only when liquid. The communicated the first high-order detonation is at a magnitude sufficient to cause the detonator to produce a second high-order detonation.

Abstract: An apparatus for controlling a wellbore energy train may include a firing head, a detonator cord associated with the firing head, and a plurality of serially aligned modules. Each module may include an enclosure, a first portion of a high order detonation material positioned at one end of the enclosure, a second portion of the high order detonation material positioned at the other end of the enclosure, and a low order detonation material interposed between the first portion and the second portion. A method for controlling an energy train generated in a wellbore may include serially aligning a plurality of the modules along the path of the energy train, and detonating at least one of the plurality of modules by detonating a detonator cord.
