    Abstract: A perforating gun may include a first housing, a charge holder positioned within the first housing and configured to receive a shaped charge, an initiator, a detonating cord configured to detonate the shaped charge, and a first spring positioned within the first housing. A relative position of the initiator and the detonating cord may be movable between a first position in which the perforating gun is ballistically unarmed and a second position in which the perforating gun is ballistically armed. The first spring may bias the initiator and the detonating cord to the first position.

    Abstract: A system for use within a gun housing of a perforating gun may include a centralizer and a detonator holder. The centralizer may include a centralizer body and a centralizer bore extending through the centralizer body. The detonator holder may be disposed within the centralizer bore and may include a first detonator holder end configured to receive a detonator and a second detonator holder end comprising a detonator holder coupling. The detonator holder may extend through the centralizer and may be mechanically coupled to the centralizer. The centralizer may be configured to engage with an inner surface of the gun housing.

    CPC classification number: E21B23/065

    Abstract: A ballistically actuated plug may include an outer carrier having a first end and a second end, a hollow interior chamber within the outer carrier, a ballistic carrier positioned within the hollow interior chamber, an initiator positioned within a bore of the ballistic carrier, and one or more ballistic components. Each of the components may be positioned within a ballistic slot on an outer surface of the ballistic carrier. The initiator and the ballistic component may be relatively positioned for the initiator to initiate the one or more ballistic components. The ballistic component may include an explosive charge for expanding the outer carrier. The ballistic carrier may be formed from a fragmenting or disintegrating material.
