Abstract
A holder for shaped charges is shown and described. The charge holder facilitates a high shot density for use with a perforating gun. The shaped charges are arranged to direct explosive force axially outward from a perforating gun. The plurality of radially spaced charges are designed to result in an annular ring of blast effect in any metal tubing associated with the oil/gas extraction operation as well as any concrete conduits in which the tubing is disposed.
