Publication number: 20070000693Abstract: A hydraulically powered tractor includes an elongated body, two gripper assemblies, at least one pair of aft and forward propulsion cylinders and pistons, and a valve system. The valve system comprises an inlet control valve, a two-position propulsion control valve, a two-position gripper control valve, two cycle valves, and two pressure reduction valves. The inlet control valve spool includes a hydraulically controlled deactivation cam that locks the valve in a closed position, rendering the tractor non-operational. The propulsion control valve is piloted on both ends by fluid pressure in the gripper assemblies. The propulsion control valve controls the distribution of operating fluid to and from the propulsion cylinders, such that one cylinder performs a power stroke while the other cylinder performs a reset stroke. Each end of the gripper control valve is piloted by a source of high-pressure fluid selectively admitted by one of the cycle valves.Type: ApplicationFiled: May 3, 2006Publication date: January 4, 2007Inventors: Duane Bloom, Norman Moore, Robert Levay

Publication number: 20070000695Abstract: A force absorbing tool is attached to a mud motor in a drilling string. The tool includes an outer housing portion that is secured to a drilling string, and an inner mandrel portion that is secured to a mud motor and is moveable axially and rotationally with respect to the outer housing portion between an axially compressed position and an axially extended position. Helical grooves are inscribed on the inner mandrel portion, and a plurality of guide pins are associated with the outer housing and disposed within the helical groove. A compressive spring member to urge the inner mandrel portion toward the axially extended position.Type: ApplicationFiled: June 30, 2005Publication date: January 4, 2007Applicant: Baker Hughes IncorporatedInventor: Walter Laflin

Publication number: 20070000696Abstract: A pressure absorbing tool is attached to a workover motor in a milling assembly. The tool includes an upper housing portion that is secured to a drilling string, and a lower mandrel portion that is secured to the workover motor and is moveable axially, but not rotationally with respect to the upper housing portion between an axially compressed position and an axially extended position. Longitudinal grooves are inscribed on the lower mandrel portion, and a plurality of guide members are associated with the upper housing and disposed within the grooves. The axially retracting design uses pressure acting across two pistons to retract as the motor stalls. The Belleville washers bias the tool to the extended position once the motor has returned to operating conditions.Type: ApplicationFiled: October 21, 2005Publication date: January 4, 2007Applicant: Baker Hughes IncorporatedInventor: Walter Laflin

Publication number: 20070000697Abstract: A method and apparatus for propelling a tool having a body within a passage. The tool includes a gripper including at least a gripper portion which can assume a first position that engages an inner surface of the passage and limits relative movement of the gripper portion relative to the inner surface. The gripper portion can also assume a second position that permits substantially free relative movement between the gripper portion and the inner surface of the passage. The tool includes a propulsion assembly for selectively continuously moving the body of the tool with respect to the gripper portion while the gripper portion is in the first position. This allows the tool to move different types of equipment within the passage. For example, the tool advantageously may be used in drilling processes to provide continuous force to a drill bit. This enables the drilling of extended horizontal boreholes.Type: ApplicationFiled: May 3, 2006Publication date: January 4, 2007Inventors: Norman Moore, Ronald Beaufort, Rudolph Krueger

Publication number: 20070000700Abstract: A twist bit for drilling mortar and for optimizing dissipation of heat and dust created by the drilling. A shaft has a flute therein configured in a spiral configuration therealong leaving a flute land thereon also configured in a spiral configuration therealong, a tip, and a head including the tip and a portion of the flute land coextensive with the tip. Diamond dust is disposed only on the flute land and the head. To optimize the dissipation of the heat and the dust created by the drilling, the twist drill operates via a drill motor in a range of approximately 25,000 RPMs to approximately 26,000 RPMs. The flute has a width of approximately ¼? and the flute land has a width of approximately ¼? and a height of approximately 1/16?.Type: ApplicationFiled: June 30, 2005Publication date: January 4, 2007Inventor: Bruce Switzer
