Fluid-disabled detonator and perforating gun assembly

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.

Smart initiator assembly

According to various implementations, a vehicle pyrotechnic initiator assembly includes an initiator that includes at least one electrode pin and a validation device in electrical communication with the at least one electrode pin. The validation device provides validation information about at least a portion of the initiator assembly and/or a safety device in which the initiator assembly is installed. The validation information may include a date associated with an expiration of the initiator assembly and/or the safety device. The validation information may also or alternatively include a manufacturer identity associated with a manufacturer of the initiator assembly and/or safety device. In some implementations, the validation device includes an electrical circuit and/or memory that stores the validation information. For example, the validation device may include an ASIC chip.
