  • Electronic Switch and Circuit for Select-Fire Perforating Guns
    Publication number: 20120250208
    Abstract: Apparatus and method are provided for select-firing of perorating guns or activating other equipment in a well, such as a bridge plug. Double-pole double-throw electronic relays, used along with diodes that block voltage below a selected level, are used to control access of positive or negative voltages to blasting caps. Firing of a blasting cap causes an open circuit across the blasting cap and shifting of a relay. Alternate application of negative and positive voltages allows activation of multiple devices in a well.
