US Patent 8020619 Severing of downhole tubing with associated cable

Methods for severing tubing having a cable extending along its length include lowering a first cutting torch into the tubing to a desired location, igniting the first cutting torch, and directing cutting fluids in a circumferential arc to form a first cut in the tubing and sever the cable. A second cutting torch can be lowered and positioned relative to the first cut, and ignited to direct cutting fluids radially to cut the tubing all around the circumference, enabling retrieval of the tubing. The need for precise positioning and alignment of the torches to sever both the cable and tubing is thereby eliminated.
