ABSTRACT:
A method of evaluating an earth formation is disclosed which includes conveying a logging tool into a borehole in the earth formation and using the logging tool to obtain a first set of azimuthally-independent resistivity measurements of the earth formation and a second set of azimuthally-sensitive resistivity measurements of the earth formation and estimating a value of a property of the earth formation using the first set of measurements and the second set of measurements, the estimation being substantially unaffected by a displacement of the logging tool from a center of the borehole.
