摘要： Downhole fluid jet cutting tools having extendible and retractable arms with cutting heads on the ends are disclosed. The jet cutting tools permit casing and other downhole surfaces to be cut utilizing a cutting fluid forced through a jet nozzle assembly. Inflation of an inflatable member within the passageway of the tool moves the jet nozzle assembly when cutting fluid pressure inflates the inflatable member. As a result, a cutting head of the jet nozzle assembly is extended and cutting fluid is forced at high pressure from the passageway to the cutting head where it is expelled through nozzles for cutting casing and the like. The jet cutting tools permit the cutting head to be extended, retracted, and re-extended or redeployed multiple times without the need for being retrieved from the wellbore.

摘要： 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.

摘要： Apparatus and methods for selectively releasing a first wellbore component (30) to a second wellbore component (40) using a disconnect device. In one embodiment, the method includes coupling a disconnect device (20) to a workstring (40) and a downhole tool (30); performing a downhole operation using the downhole tool, and selectively releasing an upper portion of the disconnect device from a lower portion of the disconnect device, thereby releasing the downhole tool from the workstring. The method may also include reconnecting the upper portion of the disconnect device to the lower portion of the disconnect device. In one embodiment, the disconnect device is capable of transferring torque to the wellbore component.
