摘要
The method evaluates borehole formations using corrected formation resistivity logs obtained from a formation evaluation tool. In accordance with the present invention the method corrects the error in the amplitude ratio resistivity curve Rar and the phase difference resistivity curve Rpd thereby providing a more accurate formation resistivity log. The method of this invention employs a low frequency mixing law such as Archie's equation in combination with a high frequency mixing law such as Complex Refractive Index Method (CRIM) to correct the measurements of wave propagation type formation evaluation tools for the effects of the dielectric constant on the tool's measured parameters.
