  • Patent number: 8347964
    Abstract: Apparatus and methods for selectively releasing a first wellbore component to a second wellbore component using a disconnect device. The method includes coupling a disconnect device to a workstring and a downhole tool; 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. The disconnect device is capable of transferring torque to the wellbore component.

  • Patent number: 8082988
    Abstract: A method and apparatus for stabilizing a downhole tool during a downhole operation. The method and apparatus include a stabilizer having a stabilization member adapted to move between a retracted position and an extended position in order to engage a surface in a wellbore. The stabilizer also includes a plurality of actuators adapted to move the stabilization members from the retracted position to the extended position.

  • Patent number: 6003787
    Abstract: An insecticide spray apparatus (5) for spraying insecticide in confined areas. The insecticide spray apparatus (5) has a spray gun (10) and a compressor assembly (14) for providing compressed air through a flow line (12) to the spray gun (10). A nozzle (36) atomizes the insecticide for fogging operations and a trigger (34) on the spray gun (10) provides on and off control of the spray action. The compressor assembly (14) has a base (22) with a handle (28) such that the compressor assembly (14) can be carried in one hand by the user. A plurality of bottle holders (24) are provided on the base (22) for carrying spare pesticide containers (30).
