A method and system for processing induction measurements of sub-surface formations taken by an induction logging system at various depths in a borehole is disclosed. The method reduces the effects of variations in the sonde response function with formation conductivity (skin effect). A filtering function is applied to the quadrature-phase X component measurement of each log measurement to obtain a correction component measurement representative of the change in the sonde response function as a function of formation conductivity. The correction component measurements are then summed with the in-phase R components to obtain a skin effect compensated log. |
