Abstract
A downhole casing cutting and removal assembly () and method of use thereof, the assembly comprising a work string () with a cutting mechanism () and plurality of resettable anchor mechanisms (B-D). The arrangement allows a test pull to be made following the cut by an anchor mechanism closer to the upper end of the cut casing section than an anchor mechanism (B-D) located close to the cutting mechanism. Time is thus saved by not having to raise and lower a single anchor mechanism (B-D) between the cutting position and the upper end of the cut casing section to undertake a test pull.
