Abstract
A back-off tool for use in breaking a joint of a tubular disposed in a well. The tool is dual anchoring in nature such that breaking of the joint may be achieved with a degree of precision heretofore unavailable. Additionally, the dual anchoring nature of the tool at both sides of the joint allows for power requirements to be met through use of a dowhole power source incorporated into the tool. As a result, the use of heavier power carrying cables and equipment may be avoided as well as explosives or similarly hazardous and/or imprecise measures.
