Patent number: 10480304Abstract: Downhole drilling vibration analysis uses an angular rate sensor on a drilling assembly. During drilling operations, the sensor measures the angular rate of the drilling assembly. Processing circuitry is operatively coupled to the angular rate sensor and is configured to determine whether torsional type vibrations are occurring during drilling based on the angular rate data. Drilling operations can then be modified to overcome or mitigate the torsional type vibrations.Type: GrantFiled: October 12, 2012Date of Patent: November 19, 2019Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLCInventors: Charles Lee Mauldin, Roger P. Bartel, Richard Berns

Patent number: 8881844Abstract: Disclosed herein is a system for steering the direction of a borehole advanced by cutting action of a rotary drill bit by periodically varying action of a drill bit while continuously rotating a drill string to which the drill bit is operationally attached. The steering system can include a bit perturbation device cooperating with a bent housing subsection and operationally connected to the drill string and to the drill bit. Drill bit action can be varied by periodically varying the rotation speed and/or rate of penetration of the drill bit. Periodic drill bit action results in preferential cutting of material from a predetermined arc of the borehole wall which, in turn, results in borehole deviation. Action of the drill bit can be varied independently of the rotation rate of the drill string.Type: GrantFiled: September 14, 2011Date of Patent: November 11, 2014Assignee: Precision Energy Services, Inc.Inventors: Steven Reid Farley, Michael Louis Larronde, Roger P. Bartel, Charles Lee Mauldin, Robert Anthony Aiello

Patent number: 6831571Abstract: A method and apparatus for transferring data from a logging tool to a surface computer that involves attaching a stand-alone data dump device to the logging tool after the logging tool has gathered data about downhole parameters. After attaching the data dump device, data contained in a memory of the logging tool is copied to a memory of the data dump device. In one embodiment, once data copying between the logging tool and data dump device is complete, the data dump device is disconnected from the logging tool and connected to a surface computer which reads the data previously copied to the data dump device. A second embodiment of the data dump device has a radio frequency communication link between the surface computer and the data dump device to allow a wireless communication between the surface computer and the data dump device and/or logging tool.Type: GrantFiled: December 7, 2000Date of Patent: December 14, 2004Assignee: Halliburton Energy Services, Inc.Inventor: Roger P.

Patent number: 6825659Abstract: A method for manufacturing NMR measurement-while-drilling tool having the mechanical strength and measurement sensitivity to perform NMR measurements of an earth formation while drilling a borehole, and a method and apparatus for monitoring the motion of the measuring tool in order to take this motion into account when processing NMR signals from the borehole. The tool has a permanent magnet with a magnetic field direction substantially perpendicular to the axis of the borehole, a steel collar of a non-magnetic material surrounding the magnet, antenna positioned outside the collar, and a soft magnetic material positioned in a predetermined relationship with the collar and the magnet that helps to shape the magnetic field of the tool. Due to the non-magnetic collar, the tool can withstand the extreme conditions in the borehole environment while the borehole is being drilled.Type: GrantFiled: June 24, 2003Date of Patent: November 30, 2004Assignee: NumarInventors: Manfred G.

Patent number: 6191561Abstract: The present invention is directed to a downhole apparatus for quickly generating and regulating variable output electric power by varying the alignment of a pair of axially adjacent permanent magnets rotating within an armature having electrically conductive windings. Each of the permanent magnets comprises a plurality of permanent magnetic segments having circumferentially alternating magnetizations. One of the permanent magnets is fixed to the drive shaft, and the other permanent magnet is movably mounted on the drive shaft to enable the alignment or misalignment, as desired, of the magnetizations of the respective magnetic segments on the pair of permanent magnets. When the magnetizations are completely aligned, the maximum electrical power is generated in the windings of the main armature; conversely, when the magnetizations are completely misaligned, zero electrical power is generated.Type: GrantFiled: January 15, 1999Date of Patent: February 20, 2001Assignee: Dresser Industries, Inc.Inventor: Roger P.

Patent number: 5278507Abstract: An apparatus and method for determining formation resistivity at a plurality of radial distances from an earth borehole uses a single receiver pair and a plurality of electromagnetic energy transmitters sequentially spaced along the apparatus from the receiver pair, such transmitters being sequentially pulsed at approximately 1-2 MHz each to provide time separation between the pulsing of the plurality of transmitters. The closest spaced transmitter is spaced a predetermined distance from the closer receiver to make the depth of investigation of the closest transmitter essentially independent of formation resistivity. Alternatively, a single transmitter is spaced a predetermined distance from the closer receiver to make the depth of investigation of such transmitter essentially independent of formation resistivity.Type: GrantFiled: June 14, 1991Date of Patent: January 11, 1994Assignee: Baroid Technology, Inc.Inventors: Roger P.
