20090301744 | Jet Hammer - An exemplary embodiment of the jet hammer includes an outer sleeve, impact assembly, and a valve assembly. The impact assembly is positioned in sliding relation to the outer sleeve to provide the impact of the jet hammer. The valve assembly generally comprises a cap screw, adjustment sleeve, valve port, inner compression spring, outer compression spring, and lock nut. The inner compression spring is relatively less compressible than the outer compression spring. In operation, fluid enters the valve assembly and acts on the compression springs forming an operational seal between the valve assembly and the impact assembly. In response, the outer sleeve is slidingly displaced from the impact assembly thereby compressing a main compression spring positioned along the mandrel shaft. Once the pressure acting on the valve assembly is released, the main compression spring decompresses forcefully causing the outer sleeve to impact a connection port, bit, tool, or other member attached to the upper end of the mandrel. This impact is translated onto the obstruction or item to be struck. The impact assembly may also be capable of rotational movement with respect to the outer sleeve wherein the mandrel shaft may contain at least one rotation nozzle thereon. The rotation nozzles allow for fluid communication from the mandrel's internal bore, through the nozzles, and against the proximate inner wall of the outer sleeve. This interaction causes the mandrel, and by connection the connection port, bit, tubing, or tool attached thereto, to rotate during the downward stroke of the hammer. Rotation nozzles may be located on the connection port and/or bit for additional rotational force. | 12-10-2009 |
20110220151 | Method and Apparatus for Washing Downhole Tubulars and Equipment - A washing assembly having at least one nozzle in fluid communication with at least one fluid source.

The washing assembly is positioned within a wellbore such that it is sufficiently retained therein. A fluid source is coupled to the washing assembly to provide pressurized fluid thereto. The fluid provided may be augmented with cleaners or other chemicals to aid in the removal of the NORM and/or other material contained on the tubulars, and/or to aid in neutralizing the NORM. The pressurized fluid is introduced into the wellbore and the tubular is extracted through the exerted fluid. The NORM and other material is washed down into the borehole. One or more washing assemblies may be positioned along the length of the wellbore as needed. | 09-15-2011 |
20120247757 | Downhole Oscillator - An exemplary embodiment of the downhole oscillator includes an outer housing at least partially surrounding a motor and a removably coupled eccentric member. The motor at least partially drives the rotation of the eccentric member thereby producing oscillations or vibrations along the outer diameter of at least a portion of the downhole assembly. The motor's action is at least partly facilitated by expulsion of fluid from the drill string through the motor and onto the outer housing interior such that the force of the fluid produces rotation in the motor. Rotation may be enhanced through similar expulsion of fluid from the eccentric member. Alternatively, the fluid may be expelled from the motor and/or eccentric member against the wellbore thereby providing the desired rotation. A method of use may include providing an outer housing, motor capable of producing rotational movement, and eccentric member and coupling same. | 10-04-2012 |
