Publication number: 20060149477Abstract: This invention provides a measurement-while-drilling (MWD) downhole assembly for use in drilling boreholes which utilizes directional formation evaluation devices on a rotating assembly in conjunction with toolface orientation sensors. The data from the toolface orientation sensors are analyzed by a processor and toolface angle measurements are determined at defined intervals. Formation evaluation sensors operate substantially independently of the toolface orientation sensors and measurements of the formation evaluation sensors are analyzed in combination with the determined toolface angle to obtain formation parameters.Type: ApplicationFiled: December 29, 2005Publication date: July 6, 2006Applicant: Baker Hughes IncorporatedInventors: Paul Cairns, Sergey Efremov, David Schneider, Sassan Dehlavi, Robert Estes, Samuel Bell

Publication number: 20050199425Abstract: A nuclear sensor on a bottomhole assembly (BHA) makes measurements of a property of an earth formation during continued rotation of the BHA. Magnetometers that are susceptible to bias error are deployed on the BHA to make measurements of the magnetic toolface angle. A processor separates the sensor measurements into azimuthal sectors while compensating for inherent time delays in the electronics, non-uniform rotation, and bias.Type: ApplicationFiled: November 29, 2004Publication date: September 15, 2005Inventors: Robert Estes, Roger Cruz, Brent Hope, Nico Foekema

Publication number: 20050056461Abstract: A two-axis gyroscope used on a bottom hole assembly can be used for determining a rate of rotation about the rotational axis of a BHA. The method takes advantage of possible misalignment of at least one axis of the two axis gyroscope from orthogonality with respect to the rotational axis of the BHA, resulting in the misaligned gyro being sensitive to BHA rotation.Type: ApplicationFiled: August 5, 2004Publication date: March 17, 2005Applicant: Baker Hughes IncorporatedInventors: Robert Estes, Jonathan Bynum, Randell Riggs, David Epplin
