Patent number: 10017992Abstract: A bearing section for a mandrel at least partially disposed within an inner bore of a housing. A radial bearing and a thrust bearing are each disposed around the mandrel and within the inner bore of the housing. The radial bearing includes an outer cylindrical member, an inner cylindrical member, and a series of spherical members disposed within a space between an inner surface of the outer cylindrical member and an outer surface of the inner cylindrical member. One of the inner surface of the outer cylindrical member or the outer surface of the inner cylindrical member includes a flat profile and the other includes a series of circumferential grooves. The flat profile allows relative axial movement between the inner and outer cylindrical members without the radial bearing absorbing any thrust load.Type: GrantFiled: November 4, 2016Date of Patent: July 10, 2018Assignee: Ashmin Holding LLCInventors: Gunther HH von Gynz-Rekowski, William C.

Patent number: 6991046Abstract: An expandable eccentric reamer for placement in a drill string up-hole of a conventional drill bit. The reamer blade is actuated by drilling fluid pressure to radially extend to a drill out diameter greater than a pass-through diameter. The reamer body is shaped to have an eccentric outer surface configuration to accommodate the reamer blade therein. The reamer blade acts as a piston arm in response to drilling fluid pressure and moves along a shaft anchored in a hump region that forms an eccentricity in the outer surface configuration of the body. The reamer blade has an outer edge configuration that positions the cutters thereon to prevent them from engaging a casing of a well borehole upon deployment.Type: GrantFiled: November 3, 2003Date of Patent: January 31, 2006Assignee: ReedHycalog, L.P.Inventors: Coy M. Fielder, Gary D. Wells, Rogerio H. Silva, William C. Herben

Patent number: 5956995Abstract: An apparatus and method for detecting lubricant reservoir levels, particularly in bearing sections for downhole mud motors, is revealed. This allows rig personnel to more exactly ascertain the remaining bearing life of the assembly. In one embodiment, the assembly is pulled out of the hole and comprises of a signal source. A hand-held device is placed next to the bearing housing and the location of the strongest signal is a direct measurement of the position of the floating piston in the lubricant reservoir. The rig personnel can then readily obtain a level reading on the fluid level in the reservoir. An alternative design is also revealed where the position of the floating piston is sensed in real-time by receivers mounted at spaced locations in the lubricant reservoir.Type: GrantFiled: September 18, 1997Date of Patent: September 28, 1999Assignee: Pegasus Drilling Technologies, L.L.C.Inventors: William C.

Patent number: 5881824Abstract: A mechanism for arients and maintains a key in a sub for guiding directional measurement equipment of a directional drilling assembly with respect to the drillbit. The orienting sub has an outer sleeve which is supported on an inner shoulder in the orienting sub. An inner sleeve which holds the key has an outer wedged profile which follows the shape of the outer sleeve. The outer sleeve can be longitudinally, obliquely, or spirally segmented and has a thread on one end so that a jam nut can be installed to advance the inner sleeve with the key until a wedging action occurs between the inner and outer sleeves and the sub. At that point, the key is oriented without any bores through the wall of the sub. Provisions can be made in the assembly to provide a biasing force on the inner sleeve which holds the key to compensate for vibrational loads on the assembly.Type: GrantFiled: May 27, 1997Date of Patent: March 16, 1999Assignee: Pegasus Drilling Technologies L.L.C.Inventors: Gunther von Gynz-Rekowski, William C.

Patent number: 5810088Abstract: In drilling equipment having at least one remote assembly (62) attached to a drill string (12), an electrically actuated disconnect apparatus and method (10) for releasing the remote assembly (62) has an electric signal transmitter electrically connected to a release device (16). The release device (16) operates a retaining device (22) holding strainer blocking devices (24) therein. A strainer (56) is connected to the drill string (12) after the retainer (22) and through which drilling fluid flows until blocked by the strainer blocking devices (24).Type: GrantFiled: March 26, 1997Date of Patent: September 22, 1998Assignee: Baker Hughes, Inc.Inventors: Brad Lamirand, William C.

Patent number: 5277055Abstract: A test stand has a base supporting standards on which are mounted a crossbar and an adjustably locatable header. The header supports an actuator for raising and lowering the crossbar which holds V-blocks for engaging the handles of an impact or impact-rotary tool and which applies downward pressure to the tool. The tool chuck is fitted to the top of a guide rod whose lower end passes with a sliding fit through a disc to which it is keyed and bears against a piston in an hydraulically pressurized cylinder. Sensors detect rotation of the disc and movement of the piston to provide information to a computer as to impact energy and rotary speed. A manifold fitted with sensors for temperature, pressure, and flow rate supplies operating air to the tool. The computer includes a database with stored information as to past history of the tool and the manufacturer's recommended operating specifications to which the measured data is compared.Type: GrantFiled: August 30, 1991Date of Patent: January 11, 1994Assignee: Consolidated Edison Company of New York, Inc.Inventors: Gerard T. Pittard, William J. McDonald, Terry P. Clifton, William C. Herben

Patent number: 4858704Abstract: Long utility holes, for gas lines, electrical conduit, communications conduit and the like, may be bored or pierced horizontally through the earth, particularly under obstacles, such as buildings, streets, highways, rivers, lakes, etc. Such holes may be bored by an underground drilling mole (underground percussion drill) supported on a hollow drill rod and supplied with compressed air through the rod to operate an air hammer which strikes an anvil having an external boring face, preferably constructed to apply an asymmetric boring force. The drill rod is operated by a drill rig on the surface or recessed in special pit for horizontal drilling and provides for additional sections of pipe or hollow rod as the boring progresses. The asymmetric boring force causes the boring path to curve and, when straight line drilling is needed, the drill rod is rotated to counteract the asymmetric boring force.Type: GrantFiled: September 9, 1987Date of Patent: August 22, 1989Assignee: Gas Research InstituteInventors: William J. McDonald, Gerard T. Pittard, William C. Maurer, Michael R. Wasson, William C. Herben
