Abstract: Methods for severing a tubular string having a cable in association therewith can include lowering a cutting apparatus into the tubular string and actuating the cutting apparatus to form a cut in the tubular string and sever the cable. Severing the cable in this manner can be performed through a single actuation of a single cutting apparatus, enabling at least a portion of the tubular string to be subsequently severed and retrieved, unimpeded by the cable.

Abstract: 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.
