Debris retention perforating apparatus and method for use of same

A perforating apparatus comprising:

• at least one shaped charge having an initiation end and a discharge end;
• a detonating cord operably coupled to the initiation end of the shaped charge;
• and
• a carrier containing the shaped charge, the carrier including at least one discharge location corresponding to the discharge end of the shaped charge when the perforating apparatus is in its operable position, the discharge location having first and second material layers wherein an opening created by a jet formed from detonating the shaped charge in the second material layer is smaller than an opening created by the jet in the first material layer.

A method for retaining debris in a perforating apparatus used to perforate a subterranean well comprising the steps of:

• running the perforating apparatus downhole;
• detonating a shaped charge contained within a carrier of the perforating apparatus;
• and
• discharging a jet formed from the shaped charge through a discharge location of the carrier such that an opening is created through first and second material layers of the discharge location wherein the opening in the first material layer is larger than the opening in the second material layer, thereby retaining debris in the perforating apparatus with the second material layer.
