Abstract
A perforating gun apparatus includes an elongated radially resilient carrier with a plurality of capsule type shaped charges attached to the carrier in a circumferentially phased pattern. The carrier is capable of passing downward through restricted diameter openings and subsequently expanding so as to hold the shaped charges with a near zero standoff from the well bore which is to be perforated.
