Abstract: A fluid cutting tool and method for perforating or severing tubular members from inside. The tool is especially suited for use with a rotational drive system, such as a downhole motor, to separate downhole structures, such as stuck production tubing. The cutting tool preferably takes the form of an elongate metal body with an open first end connectable to the end of a downhole motor. The downhole end of the tool may be conical. A fluid conduit within the body of the tool communicates with the fluid channel in the downhole motor. Ports in the sides of the tool body direct jets of cutting fluid out the side of the tool. The tool attached to the motor is fed downhole until the tool is at the desired location in the well. Then the motor is operated to rotate the tool while cutting fluid is pumped through it. This causes the jets of fluid to be directed at the inner surface of the production tubing (or other tubular structure). This process is continued until the tubing is perforated or severed, as needed.

Abstract: Method and apparatus for drilling, completion, well workovers and well control, combining an integrated lifting unit and a coiled tubing unit, the method and apparatus permit running jointed pipe and coil tubing in combination, and standing multiple joints of pipe near the unit. The invention combines a hydraulic pipe hoisting system, pipe handling systems and pipe racking containment apparatus. A hydraulic workover jack is combined with a multifunction injector head and a standpipe for fluid circulation. The invention may also include a rotary table for rotating pipe and/or a rotating power swivel to allow fluid circulation during pipe rotation. Also included are a gin pole, a winching system for jointed pipe, and a traveling head with traveling slips and stationary slips to allow pipe movement in the well. Hydraulic systems allow insertion and extraction of tools in a work string.
