Patent number: 9273522Abstract: A method, apparatus and computer-readable medium for reducing a vibration of a drill string in a borehole. A sensor of the drill string obtains one or more measurements of a parameter of the vibration. A processor determines at least one force for controlling the measured vibration from the measured parameter. At least one actuator applies the determined at least one force against the borehole wall to control the vibration of the drill string.Type: GrantFiled: February 6, 2012Date of Patent: March 1, 2016Assignee: Baker Hughes IncorporatedInventors: Olof Hummes, Matthias Meister, Sven Krueger, Bernd Santelmann, Michael Koppe

Patent number: 8689905Abstract: An apparatus for use in a wellbore is provided, which in one embodiment includes a drilling motor and a steering unit placed about a shaft between a lower section of a stator in the motor and a drill bit. The steering unit includes a substantially non-rotating member and a force application member on the non-rotating member configured to radially extend the force application member from the non-rotating member. In another embodiment, the steering unit may include, rotating member configured to rotate a drill bit, a steering member configured to orient the drill bit along a selected direction, a first steering device configured to orient the steering member in the wellbore, and a second steering device configured to maintain orientation of the steering member when drilling the wellbore.Type: GrantFiled: November 23, 2010Date of Patent: April 8, 2014Assignee: Baker Hughes IncorporatedInventors: Sven Krueger, Michael Koppe, Bernd Santelmann, Thomas Kelch, Niko Spreckelmeyer, Olof Hummes

Patent number: 8408304Abstract: A bearing for a wellbore tool includes a flow device. The flow device may be a pump such as a positive displacement pump or a hydrodynamic pump. In arrangements, a pump stator connects to a wellbore wall. A pump rotor rotates with a drilling motor, and/or a drill string. Rotation of the pump rotor may generate a pressure differential to displace the fluid. The pump may be configured to flow fluid across a gap between a rotating section and a non-rotating section of the bearing. The fluid may be drawn from a wellbore annulus and also returned into the wellbore annulus. The bearing may support thrust loadings and/or a radial loadings. In embodiments, inserts in the bearing may be used to filter the fluid.Type: GrantFiled: March 25, 2009Date of Patent: April 2, 2013Assignee: Baker Hughes IncorporatedInventors: Olof Hummes, Bernd Santelmann, Sven Kruger

Patent number: 8360172Abstract: An apparatus for drilling a wellbore may include a first section, a second section, and a third section, all of which are rotatably interconnected with pivot bearings and positioned along a drill string. The second section and the third section may be configured to form a controllable bend angle in the drill string. The first section, the second section, and the third section may be configured as sleeves that surround a portion of the drill string. One or more sections may include locking pads that selectively engage a wall of the wellbore. A hydraulic locking device for controlling a direction of rotation of the second section may include one or more brake elements and a reverse spinning sleeve. A first brake element may be used engage the reverse spinning sleeve and a second brake element may be used to engage a drive shaft.Type: GrantFiled: April 14, 2009Date of Patent: January 29, 2013Assignee: Baker Hughes IncorporatedInventor: Bernd Santelmann

Patent number: 8286729Abstract: A method for determining wellbore trajectory includes determining survey parameters in the wellbore; measuring force parameter(s) in the wellbore; and correcting the survey parameters using the measured force parameter(s). The downhole measured force parameters may include forces associated with an operation of a steering device such as an internal reaction force, and/or a bending moment. In variants, the method may include measuring a wellbore temperature; measuring a wellbore parameter in addition to the temperature; and correcting a survey parameter using the measured parameter and the measured temperature. These methods may include correcting survey parameters using measured wellbore diameters. Also, a processor in the wellbore may be programmed to perform the correction while in the wellbore and/or control a steering device using measurements provided by a sensor for measuring internal reaction forces.Type: GrantFiled: February 12, 2009Date of Patent: October 16, 2012Assignee: Baker Hughes IncorporatedInventors: Hanno Reckmann, Frank Schuberth, Bernd Santelmann
