Title: SLICKLINE RUN HYDRAULIC MOTOR DRIVE TUBING CUTTER
Abstract:
A tubing cutter is run in with a bottom hole assembly that includes a seal and support within the tubing to be cut. A ported sub allows pressurized fluid pumped from the surface to enter the bottom hole assembly above the sealed support location and to be directed to set an anchor and to a fluid driven motor such as a progressive cavity motor that is in turn connected to the tubing cutter at the rotor of the progressive cavity motor. The rotation of the cutter with its blades extended cuts the tubular as the fluid exiting the stator goes to the lower end of the tubing being cut and can return to the surface through an annulus around the tubing to be cut. Other configurations such as cutting casing or cutting casing through tubing are also envisioned.
