Abstract

A well perforating gun having stress relieved scallops. A well perforating gun includes a gun body having at least one scallop formed in a sidewall of the gun body. At least one stress relief element, such as a radius or chamfer, is formed between the scallop and an outer surface of the gun body. The stress relief element may extend in a plane which extends longitudinally or laterally relative to the gun body, and may intersect a centerline of the scallop. The stress relief element reduces stress in the gun body due to a pressure increase in the interior of the gun body.
