Abstract
A perforating gun includes an outer sleeve included of a generally tubular wall structure having a peripheral surface around the outside, opposite ends thereof and a central passage therethrough extending from one end to the other end and further including a connection at each end to connect to other tools in a tool string wherein the outer sleeve is configured to carry the tensile and compressive forces imposable on the perforating gun as the perforating gun is deployed in the wellbore, and at least one pressure sealed perforating module installed within the central passage of the outer sleeve having a shaped charge sealed therein and wherein the installation of the pressure sealed perforating module within the outer sleeve is configured to substantially eliminate the transfer of tensile or compressive forces imposable on or by the tool string onto the at least one pressure sealed perforating module.
