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.

Abstract: A technique facilitates on-demand release of desired sections of a well string, e.g. sections of a perforating gun string, via at least one on-demand release tool. The on-demand release tool has an activation mechanism which may be selectively actuated to transition the on-demand release tool from a first loadbearing configuration to a second loadbearing configuration. The on-demand release tool may then be transitioned to a release stage which allows a first section of the on-demand release tool to be separated from a second section of the on-demand release tool by activating a release mechanism. In at least some applications, the on-demand release tool also comprises a ballistic transfer device to enable reliable ballistic transfer between sections of the perforating gun string.
