The coil tubing conduit has discharge ports positioned to allow discharge of the liquid at or near the gun to provide cooling of the gun's electrical transmission line and the gun's moving parts. The gun may be gradually withdrawn from the production zone while continuing to fire the gun to stimulate the production zone.
