Abstract
The present invention is an improvement in the design of a perforating gun to perforate the casing in oil and gas wells. Perforating guns have a cylindrical body member with explosive charges at specified intervals designed to shoot outwardly through the body member, the well casing, cement sheath, and into the rock formation. Continuous faceted cuts in the vessel covering the greater part of the circumference, at the level of the charge, serve to reduce the outward distortion of the body member beyond the original diameter of the body member. Reducing the distortion serves to insure that the perforating gun can be removed from the well after the explosive charges have fired.
