The Reservoir Group Hydraulic Tubing Cutter is a 3-bladed, hydraulically-activated cutting device used to cut down-hole production tubing, casing and drill pipe.
The tool is ran in conjunction with a down-hole motor on Jointed Pipe or Coiled Tubing. A high expansion hydraulic anchor is also available, and is typically included in the cutting assembly to prevent any movement of the cutter during activation- a common cause of failure. The tool incorporates a dual-activation piston which increases the axial load on the cutter blades, ensuring a clean and efficient cut.
Circulation through the jet sub creates the internal pressure required to shift the dual-piston and blade cams, forcing the cutter blades to expand. The jet sub incorporates interchangeable nozzles to adjust the flow rate required to achieve the desired activation pressure. Upward-facing jets help clean the cut area while also cooling the cutter blades. On completion of the cut, the spring-loaded blade-return mechanism ensures the cutter blades are returned to the “run-in” position and retained within the body of the tool.The cutter blades can be dressed with a variety of cutting structures, with each set of blades purpose-built and designed to suit the particular size and grade of tubing/ casing to be cut.
