Publication number: 20120084051Abstract: A method and an arrangement for magnetically determining a position using a permanent magnet is described, wherein the vector and local gradient of the magnetic flux density of the permanent magnet is measured using a position sensor, and the position and orientation of the magnetic dipole of the the permanent magnet relative to the position sensor is calculated from the measured values. A spherical permanent magnet having homogenous magnetization is used in the method and the arrangement, preventing previously present cross-sensitivity between the position and orientation determination, and allowing measurement without prior calibration.Type: ApplicationFiled: May 21, 2010Publication date: April 5, 2012Applicant: FRAUNHOFER-GESELLSCHAFT ZUR FORDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Michael Hackner, Volker Peters, Josef Sauerer

Patent number: 7866415Abstract: An exemplary device carried on a rotating drill string includes an actuator that moves force application members and an associated controller. The force application members are actuated by an eccentricity between a force application members housing and the actuator. The controller synchronizes the extension of the force application members with the rotation of the drill string such that a steering force applied by the force application members is applied in the same azimuthal direction. The controller may also control magnitude of the steering force by adjusting the eccentricity. Another exemplary device maintains a wellbore device, such as a sensor, in a substantially non-rotating condition relative to a reference frame. The device includes a sensor conveyed by a rotating wellbore tubular, a drive configured to rotate the sensor; and a processor that controls the drive to maintain the sensor in a substantially non-rotating condition relative to the reference frame.Type: GrantFiled: August 13, 2008Date of Patent: January 11, 2011Assignee: Baker Hughes IncorporatedInventor: Volker Peters

Patent number: 7808859Abstract: An oscillating shear valve system for generating pressure fluctuations in a flowing drilling fluid comprising a stationary stator and an oscillating rotor, both with axial flow passages. The rotor oscillates in close proximity to the stator, at least partially blocking the flow through the stator and generating oscillating pressure pulses. The rotor passes through two zero speed positions during each cycle, facilitating rapid changes in signal phase, frequency, and/or amplitude facilitating enhanced, multivalent data encoding. The rotor is driven by a motorized gear drive. In one embodiment, a torsional spring is attached to the motor and the resulting spring mass system is designed to be near resonance at the desired pulse frequency. The system enables the use of multivalent encoding schemes for increasing data rates.Type: GrantFiled: October 9, 2007Date of Patent: October 5, 2010Assignee: Baker Hughes IncorporatedInventors: Detlef Hahn, Volker Peters, Cedric Rouatbi, Heiko Eggers
