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.
