Abstract

A perforating gun comprising an elongated shaped scallop that is cut circumferentially in an outside surface of the perforating gun such that said scallop has a constant thickness portion and a variable thickness portion. The variable thickness portion is cut on either end of the constant thickness portion and an arcuate length of the constant thickness portion subtends an angle at a center of said perforating gun. The elongated shaped scallop aligns to shaped charges that are oriented along a desired perforating orientation in the perforating gun. During perforating, the shaped charges perforate through the elongated shaped scallop such that a burr created by the plural shaped charges does not substantially protrude past an outside diameter of the perforating gun.
