Abstract
A perforating apparatus incorporating a selective self-sealing material is disclosed for sealing exit holes in a wall of the apparatus resulting from perforation operations. The perforating apparatus traps debris produced during downhole perforation operations and prevents the debris from entering the wellbore which avoids the need for remedial operations to remove debris from the wellbore. The self-sealing material may be disposed within the perforating apparatus adjacent to an interior surface of the wall or the self-sealing material may be disposed outside the perforating apparatus adjacent to an exterior surface of the wall. The self-sealing material may include an expandable polymer material, a swelling elastomer, a rubber and combinations thereof.
