Patent ID: 7036595

Claim:
A method of removing a first tubular from a second tubular disposed in a well, comprising: lowering a removal tool into the well such that the removal tool engages an inner surface of the first tubular in the well, wherein the removal tool includes a lower body and an upper body, the upper body having circumferentially disposed end segments and the upper body disposed relative to the lower body such that relative movement between the upper body and the lower body can occur; rotating the removal tool such that the removal tool penetrates farther into engagement with the first tubular; positioning an overshot skirt in the well between the first and second tubulars; locating the first tubular in a space defined between the overshot skirt and the upper body; applying a lifting force to the removal tool such that at least one of the lower body and the upper body moves longitudinally relative to the other and in response the circumferentially disposed end segments of the upper body move outwardly to be wedged against the first tubular trapping the first tubular between the upper body and the overshot skirt; pulling the removal tool and at least a portion of the first tubular out of the well; and connecting a pulling device to the lower body in place of the removed tip, and pulling on the pulling device to move the lower body in a direction relative to the upper body to release the upper body such that the circumferentially disposed end segments of the upper body are not wedged against the first tubular.
