Abstract: A system for landing a perforating gun in a particular orientation may include a landing housing securable within a wellbore and having at least one key slot extending into an inner surface of the landing housing. The system further includes a latch assembly configured to couple to the landing housing in a particular orientation. The latch assembly includes a tubular support structure and at least one key feature configured to extend and retract radially through a sidewall of the tubular support structure. The latch assembly further includes a biasing mechanism configured to bias the at least one key feature into the at least one key slot to couple the latch assembly to the landing housing. Additionally, the system includes a perforating gun system secured to the latch assembly such that the orientation of the latch assembly aims the perforating gun system in the wellbore.

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.
