US 2022/0178230 A1 · RETRIEVABLE PERFORATING GUN ASSEMBLY AND COMPONENTS

Abstract

A perforating gun assembly includes an exposed perforating gun module. The exposed perforating gun module includes a housing having a first connector end, a second connector end opposite and spaced apart from the first connector end, and a chamber extending along a central axis of the housing between the first and second connector ends. The chamber is configured for receiving a detonator and optionally, a radial booster charge coupled to the detonator. A plurality of sockets extends from an outer surface of the housing towards the chamber. Each socket is configured to receive an encapsulated shaped charge. The encapsulated shaped charges may include a protrusion having an external thread that threadingly engage a complimentary threaded portion of the sockets. The detonator may directly initiate the radial booster charge or the encapsulated shaped charges.
