Abstract: A tubing conveyed perforating apparatus is shown which includes a tubular assembly made up of a plurality of tubular sections. A plurality of explosive charges are located within the interior bore of at least two of the tubular sections of the tubular assembly. A firing head is carried on the tubular assembly for detonating the explosive charges to perforate a surrounding well bore. The firing head has a concentric detonator arrangement within a hollow central bore. The explosive charges are held within the interior bore of the tubular section by a support. The explosive charges and charge support are comprised of materials which disintegrate upon detonation of the explosive charges, whereby the interior bore of the tubular assembly is fully open after detonation.

Abstract: A tubing conveyed perforating apparatus is shown which includes a tubular assembly made up of a plurality of tubular sections. One or more elongate charge holders are located within the interior bore of the tubular assembly and carry explosive charges thereon. A firing head is carried on the tubular assembly for detonating the explosive charges to perforate a surrounding well bore. The charge holders and explosive charges are comprised of materials which disintegrate upon detonation of the explosive charges, whereby the interior bore of the tubular assembly is fully open after detonation.
