Abstract
A method for perforating a well using a rust resistant well perforating gun can include disposing coatings over the rust resistant well perforating gun to prevent rust, loading a charge into a charge hole, engaging a detonation cord with the charge and an actuator, engaging the charge loading tube into the gun carrier, lowering the rust resistant well perforating gun into the well, actuating the actuator, and exploding the charge to: form a high pressure in the gap, allow jets to pierce the recesses to produce high energy pulses, and fractionate the formation using the high energy pulses.
