摘要： A method, apparatus and computer-readable medium for evaluating an earth formation includes making measurements with a logging tool having a first depth of investigation in a borehole in the earth formation. A first dip of the formation is estimated using multi-component measurements. The estimated dip is compared with a second dip measurement in the borehole. The results of the comparison are stored on a tangible medium.

摘要： 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.

摘要： A misalignment angle between the transmitter and receiver antenna of a multicomponent induction logging tool are estimated from quadrature component signals at multiple frequencies. A transmitter antenna having a first axial direction on a logging tool is excited at a plurality of frequencies. Signals responsive to the excitation are received at a receiver antenna having a second axial direction. A direct field between the transmitter antenna and the receiver antenna is obtained by performing multi-frequency focusing of the received signals. The misalignment angle is estimated from the direct field.
