Abstract
An oilfield band cutter is useful for removing a band from a tubing string structure as the tubing string structure is being pulled up from the well. The oilfield band cutter includes a base frame with a central hole, an axis extending vertically and centrally through the frame coaxial with the central hole. A tubing follower member is coupled to the base frame and is positioned against an outer surface of the tubing string structure. A cutter is coupled to the tubing follower member, the cutter including an underside having a cutting edge. The cutting edge is positioned to engage against and cut bands on the tubing string structure.
