An inventive apparatus is disclosed for use in perforating an oil or gas well. The inventive perforating gun assembly comprises at least a first and a second perforating gun module. Each of the modules has a first and a second end. Each perforating gun module comprises a perforating gun section (the perforating gun section consisting of one or more perforating guns connected together), that has a first and a second end, a first pressure test connector operably connected to the first end of the perforating gun section and a second pressure test connector operably attached to the second end of the perforating gun section. When the pressure test connectors are operably attached to each end of the perforating gun section, the pressure test connectors are capable of holding sufficient pressure for pressure testing of the complete perforating gun module. The at least two perforating gun modules are operably connected together to form the gun assembly. Also disclosed is an improved method for creating and using leak-proof perforating gun assemblies in oil or gas wells. The method comprises building the perforating gun modules described above, and pressure testing each of the perforating gun modules. After pressure testing the modules are operably connected with each other to create the gun assembly for running into the wellbore. The inventive apparatus and method improves leak prevention in perforating gun assemblies, thereby making the assemblies safer to use and operate.
