1. A perforating gun system comprising:
- shaped charges; and
a carrier housing containing the shaped charges and having a predetermined pattern of scallops, wherein the shaped charges have a plurality of possible arrangements with respect to the predetermined pattern of scallops to provide one of a plurality of different phasing patterns, and wherein the different phasing patterns include different spiral phasing patterns, and each of the different spiral phasing patterns provides the same shot density.

Abstract
A perforating gun system includes shaped charges and a carrier housing containing the shaped charges and having a pattern of scallops (or other forms of perforating jet passageways). The shaped charges have one of a plurality of arrangements with respect to the scallops to provide one of a plurality of different phasing patterns and/or shot densities. The pattern of scallops includes a first set that provides a first phasing pattern and a second set that provides a second phasing pattern.
