Abstract

A system and a method of providing a reliable and consistent time delay in an oil and gas exploration/recovery device inserted in a bore hole is presented. The reliability and consistency of the time delay is a result of the use of electronic circuitry in determining the length of time delay. The system and method presented provide a time delay unit that is modular/commoditized, facilitating quick and easy integration of each component of the time delay unit in the field. Further, assembly and disassembly of the time delay unit is easily accomplished in the field and may be designed to operate with standard percussion and detonation elements.
