Abstract:
1. A spear and tubular cutter combination, comprising: a mandrel continuously rotatably mounted in an outer assembly, said mandrel supporting a tubular cutter for tension cutting a tubular and having a flow passage therethrough that remains open for fluid flow in the direction of said tubular cutter as said mandrel rotates said tubular cutter; a mechanically operated anchor mounted to said outer assembly and configured to allow said outer assembly to enter the tubular for multiple deployments and releases of said anchor with respect to the tubular in a single trip to let said cutter cut the tubular with a tensile force on the tubular applied through said mandrel to said outer assembly when said mandrel is held axially stationary that is of a magnitude to at least support the weight of a tubular segment being produced by said tubular cutter, and in different locations in said tubular; and an outer assembly diverter and bypass passage around said diverter through said outer assembly that is normally open when said tubular cutter is operational and selectively closed to flow in opposed directions with mandrel movement for well control so that return fluid from said cutter at least in part bypasses said anchor and said diverter with said diverter in contact with the tubular and said tubular cutter is operational.
