SELF-SHUNTING DETONATOR FOR WELL PERFORATING GUN
Abstract: various well-perforating systems and methods are disclosed incorporating a self-shunting detonator. the detonator may include an electrically-conductive detonator body. a resistor initiator inside the detonator body includes first and second leads. a grounding element inside the detonator body couples the detonator body to the first lead. an electrically-conductive clip coupled to the second lead includes an arm biased to electrical contact with an external surface of the detonator body to shunt the detonator. the arm is moveable away from the detonator body to un-shunt the detonator, such as automatically in response to insertion into a detonator housing.
