Abstract
A perforating system having a perforating gun with a tubular gun housing defining an inner volume and extending in an axial direction. A shaped charge is held in a loading tube. The loading tube is located in the gun housing. The loading tube extends along the axial direction. The shaped charge faces in a firing direction substantially perpendicular to the axial direction. A portion of the gun housing adjacent to the shaped charge in the firing direction is a perforating portion for removal upon firing of the shaped charge. An eccentralizer member extends from the perforating gun in a second direction that is substantially opposite and parallel with the firing direction. A first retainer part extends from an outer surface of the gun housing adjacent to the perforating portion. A second retainer part extends from the outside of the gun housing adjacent to the perforating portion.
