Publication number: 20130166213Abstract: A logging tool having a plurality of spatially separated antennas is provided and used to make propagation-style measurements in a formation. Tensors are formed using the propagation-style measurements and one or more quantities are computed using the tensors. A formation evaluation is performed using the computed quantities. The formation evaluation determines a formation property or parameter such as horizontal resistivity, vertical resistivity, relative dip, azimuthal dip, bed boundary location, or bed thickness. The computed quantities may include compensated phase shift resistivity, compensated attenuation resistivity, symmetrized phase shift resistivity, symmetrized attenuation resistivity, anti-symmetrized phase shift resistivity, and anti-symmetrized attenuation resistivity. The measurements may be corrected for antenna gain errors and an air calibration may be performed.Type: ApplicationFiled: December 21, 2011Publication date: June 27, 2013Inventors: Dean M. Homan, Mark T. Frey, Sergiv Kryukov

Publication number: 20120111561Abstract: A method detects at least one phase of multiphase borehole fluids within a borehole. The method has a step of providing coiled tubing connected to a top end of a bottom hole assembly having a sensor configured to detect a property associated with the multiphase borehole fluids. Further, the method has a step of positioning the sensor adjacent to a first phase of the multiphase borehole fluids by rotating the bottom hole assembly or a portion of the bottom hole assembly. Moreover, the method has the steps of detecting a first measurement with the sensor as the sensor rotates and determining a fractional amount of at least one phase of the multiphase borehole fluids.Type: ApplicationFiled: October 3, 2011Publication date: May 10, 2012Inventors: Mark T.

Patent number: 7279889Abstract: By breaking the calibration into two parts—one calibration offset being associated with a first portion, and the other calibration offset being associated with a second portion, it is possible to combine the various calibration offsets for a particular first portion mated with a particular second portion. Thus, any one of a number of downhole first portions can be combined, on a session-by-session basis, with any number of second portions. In one embodiment, the second portion calibration is specific to the particular second portion, and in another embodiment the calibration for a second portion is a fixed calibration offset that is based on a second portion type, such as the second portion size.Type: GrantFiled: March 31, 2006Date of Patent: October 9, 2007Assignee: Schlumberger Technology CorporationInventor: Mark T.
