  • Correction of multi-component measurements for tool eccentricity in deviated wells
    Patent number: 7778778
    Abstract: Measurements made by a multi-component induction logging tool are corrected for tool eccentricity in a deviated borehole. The eccentricity angle is determined from single frequency skin-effect corrected data and is then used to correct multifrequency data. Multifrequency focusing is then applied to the corrected multifrequency data. An inversion is then used to recover formation resistivity and relative dip and azimuth of the borehole.
    Type: Grant
    Filed: July 30, 2007
    Date of Patent: August 17, 2010
    Assignee: Baker Hughes Incorporated
    Inventors: Alexandre N. Bespalov, Gulamabbas Merchant, Cynthia Dong Xue, Luis M. Pelegri, Michael B. Rabinovich, Stephen V. Painchaud, Bill H. Corley, Stanislav W. Forgang, Randy Gold
