Abstract

A perforating gun apparatus includes a carrier gun body having a plurality of jet target regions. A first set of the jet target regions has a first resistance to jet penetration and a second set of the jet target regions has a second resistance to jet penetration. A charge holder is positioned within the carrier gun body. A plurality of shaped charges is supported by the charge holder. A first set of the shaped charges is oriented to have discharge ends aligned with the first set of the jet target regions and a second set of the shaped charges is oriented to have discharge ends aligned with the second set of the jet target regions such that firing the first set of the shaped charges creates perforations having a first penetration profile and firing the second set of the shaped charges creates perforations having a second penetration profile.
