Abstract: A casing cutting and retrieving tool is described which includes a grapple device (2) for mechanically gripping casing to be retrieved. A mud motor having upper and lower stators (70, 73) and a rotor is also provided. The upper stator (70) acts as a suspension device for suspending the grapple device (2) from a drill string, and the upper stator (70) is mechanically fast with the grapple device (2). A rotary cutter (76) depends from a drive end (74) of the rotor and is rotatable by the rotor to cut the casing at a location below the grapple device (2).
