PERFORATING GUN ASSEMBLY AND METHOD OF FORMING WELLBORE PERFORATIONS
First Claim
Patent Images
1. A charge carrier for a perforating gun assembly, the charge carrier comprising:
- a substantially hollow tubular member having a longitudinal axis;
a plurality of apertures in the tubular member for accommodating a plurality of shaped charges, the apertures oriented with axes corresponding to the desired axes of their respective shaped charges;
wherein the plurality of apertures is configured to accommodate a plurality of groups of shaped charges disposed on the charge carrier, wherein at least two shaped charges within each group are arranged to generate jets oriented substantially along respective axes that converge towards one another and interact to form a perforation channel;
wherein the plurality of apertures is configured such that the at least two groups of shaped charges overlap one another in a longitudinal direction of the charge carrier.

Abstract
A perforating gun assembly used to form perforations in a wellbore includes a charge carrier having a longitudinal axis, and multiple groups of shaped charges that are disposed on the charge carrier. Two or more of the shaped charges within each group are arranged to generate jets oriented substantially along respective axes that converge towards one another. Also, two or more of the groups of shaped charges overlap one another in a longitudinal direction of the charge carrier.
