Patent ID: 8571797

Claim:
A method to determine one or more borehole corrected formation properties, comprising: performing measurements using a logging tool disposed in a borehole penetrating an earth formation; determining an apparent conductivity tensor for the formation using the measurements; determining from the measurements, for a set of parameters, a parameter value for each parameter in a subset of the set of parameters; providing a parameter value for each parameter in the set of parameters not in the subset; computing a borehole-inclusive modeled conductivity tensor using the parameter values, wherein the borehole-inclusive modeled conductivity tensor includes the effects of the borehole; iteratively using the apparent conductivity tensor and the borehole-inclusive modeled conductivity tensor to optimize the parameter values; using the optimized parameter values to compute an optimized conductivity tensor; computing a borehole corrected conductivity tensor using the optimized conductivity tensor; and determining the borehole corrected formation properties using the borehole corrected conductivity tensor and/or the optimized parameter values.
