Abstract: A detonation module for a perforation tool is described herein. The detonation module includes a detonator, a switch circuit disposed in a fluid-sealed housing and electrically coupled to the detonator, a shielding circuit coupled to the switch circuit, an annular electrical contact electrically coupled to the switch circuit, and an annular, electrically conductive, compressive member to form a compressive electrical connection with an end of a perforation unit.

Abstract: Embodiments of the present disclosure may provide a perforation tool and method for operating the perforation tool. The perforation tool may include one or more firing heads and one or more gun assemblies. The perforation tool may also include a release mechanism coupled to the one or more firing head and the one or more gun assemblies. The release mechanism may release the one or more gun assemblies to a bottom of a wellbore upon firing of the one or more gun assemblies and maintain the one or more firing heads on the perforation tool.
