Abstract

An apparatus is established which facilitates the cutting and removal of well casing on a single trip into the wellbore. The apparatus is run into the wellbore on the tubing string and provides a rotatable sleeve including grapples adapted to engage the casing, and to facilitate removal of the casing. The apparatus also includes cutting assemblies coupled to the mandrel, which may be rotated so as to cut the casing, thereby facilitating removal of the casing through use of the grapples. <IMAGE>
