Detonation control modules and detonation control circuits are provided herein. A trigger input signal can cause a detonation control module to trigger a detonator. A detonation control module can include a timing circuit, a light-producing diode such as a laser diode, an optically triggered diode, and a high-voltage capacitor. The trigger input signal can activate the timing circuit. The timing circuit can control activation of the light-producing diode. Activation of the light-producing diode illuminates and activates the optically triggered diode. The optically triggered diode can be coupled between the high-voltage capacitor and the detonator. Activation of the optically triggered diode causes a power pulse to be released from the high-voltage capacitor that triggers the detonator.

27 Firing system for a perforating gun including an exploding foil detonator EP94401941.3 1994-09-01 EP0651229A2 1995-05-03 Lerche Nolan C.; Aseltine Clifford L.; Voreck, Wallace E. Jr

A firing head for a firing system adapted for use in a perforating gun includes an outer pressure bulkhead housing which simultaneously conducts two separate and independent currents: a wireline current from a wireline and a return current from an initiator embodied in the firing head. A fire set circuit provides a discharge pulse to the firing head, and a wireline conductor cable provides a wireline current to the fire set circuit. The firing head includes an outer pressure bulkhead housing adapted for conducting the wireline current from the wireline conductor cable to the fire set circuit, and an exploding foil initiator (EFI) responsive to the discharge pulse from the fire set circuit for initiating the detonation of a secondary explosive. The discharge pulse energizing the firing head passes through the exploding foil initiator (EFI) and emerges from the EFI as an EFI return current. As a result, the outer pressure bulkhead housing of the firing head conducts two separate and independent currents: the EFI return current from the EFI to a ground potential, and the wireline current from the wireline conductor cable to the fire set circuit.
