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: 8602127Abstract: A bottom hole assembly has a drill bit that is driven by a downhole turbine. The turbine speed is reduced by cycloidal gearing that requires no temperature sensitive seals when operating temperatures in some applications exceed 350 degrees F. The output shaft of the cycloidal gear reducer goes through a bearing before connection to the drill bit or associated reamer. The motive fluid can be the drilling mud. The bit can be driven at desired speeds such as 50-300 RPM while the speed reduction ratio can be in the order of 10 to 1 or more. This drive assembly can replace Moineau type downhole motor drivers that have temperature limitations due to use of rubber in the stators.Type: GrantFiled: December 22, 2010Date of Patent: December 10, 2013Assignee: Baker Hughes IncorporatedInventor: 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
