ABSTRACT:
An improved perforating gun having a tubular housing, a tubular carrier and a charge carried by the tubular carrier. The tubular carrier comprises an inside diameter, an outside diameter and an opening disposed between the inside diameter and the outside diameter. The charge comprises a forward end positioned in the opening between the inside diameter and the outside diameter. The tubular carrier increases a collapsible-pressure rating for the housing and positions the charge closer to the formation.
