US Patent 11506030 Perforating gun system

An improved perforating gun is provided. The perforating gun includes an outer loading tube, an internal charge holder, an addressable switch housing, and a detonator housing. In some embodiments, the addressable switch housing and the detonator housing are separate components that are joined to the outer loading tube. In other embodiments, the addressable switch housing is integrally joined to a first portion of the internal charge holder and the detonator housing is integrally joined to a second portion of the internal charge holder. When detonated, a plurality of shaped charges create a plurality of perforations through a wellbore casing, the perforations being angularly offset from each other within a single perforation plane, optionally followed by a hydraulic fracturing stage.
