Abstract
A method and apparatus for removal of tools, tubulars, casing, or other components that become stuck in a well. An anchor includes a mandrel, a carrier disposed on the mandrel and movable relative to the mandrel between an extended position and a retracted position, and an insert configured to engage an internal surface of a tubular, the insert movably disposed in the carrier as the carrier moves between the extended position and the retracted position. A method for anchoring a tool in a wellbore includes deploying the tool into the wellbore through a tubular to a first position, the tool comprising an anchor having a carrier and an insert disposed in the carrier, extending the carrier towards the tubular, and moving the insert relative to the carrier while engaging the inserts with the tubular, thereby anchoring the tool in the wellbore.
