Abstract

An expendable EBW firing module (22) for use with a perforating gun system including a source of DC power (40) at the surface and supplied to the system through a wireline cable (18) interconnected therebetween, without requiring any additional perforating gun hardware. The module includes a high-voltage -multiplier circuit (32) for multiplying a first voltage related to the voltage received from the power source (40) by a predetermined multiple to generate a second DC voltage capable of detonating an EBW detonator (22), a firing circuit (39) for receiving the second voltage fromthe multiplier for application to the detonator (22), and an electronic safety circuit (35) interposed between the power source (40) and the multiplier (32) for preventing unintentional activation of the multiplier (32) by stray voltages present at the wellsite. The module is adapted for mounting directly in the interior housing of the perforating gun system adjacent the detonator without protection from the perforating gun charge blast and wherein the module is substantially destroyed upon activation of the detonator.
