A casing cutting and recovery tool (10) having a cutting assembly (21), an expansion assembly(60) having one or more deforming members (66), and a recovery assembly (80) is used to cut a window in wellbore casing, secure a removable segment of wellbore casing that was previously disposed within the window, and recover the removable segment of wellbore casing with the tool. One or more cutting assemblies provides one or more cuts in the wellbore casing. The deforming members (66) of the expansion assembly then expand outwardly at least two portions (100, 102) of the wellbore casing(90) shaped by the cut or cuts. The recovery assembly secures the removable segment (110) of the wellbore casing (90) to the tool so that the tool and the removable segment of wellbore casing can be recovered together from the wellbore. |
