Abstract

A detonator for use with perforating gun assemblies is presented. The detonator includes a shell including a main explosive load. The shell may include one or more openings. A non-mass explosive body is disposed in the shell, adjacent the main explosive load. The non-mass explosive body includes one or more channels extending therethrough. The detonator includes a plug adjacent the non-mass explosive body, and a PCB adjacent the plug to facilitate electrical communication with the detonator. The plug may include an elongated opening extending therethrough. The channels of the non-mass explosive body, in combination with at least one of the openings of the shell or the elongated openings of the plug, are configured to introduce fluids, such as wellbore fluids, into the non-mass explosive body to disable the detonator.
