Abstract:
1. A method for adjusting well logging data for effects of frequency dispersion, the method comprising: (a) providing a general model that includes a plurality of admittance parameters; (b) providing a tool suitable to measure conductivity and dielectric constant of a downhole formation by employing a first and a second interrogation frequency; (c) positioning the tool at a selected location within a borehole; (d) disposing the tool to measure, a portion of earth formation surrounding the selected location to obtain first and a second sets of data, the first set of data indicative of a first conductivity measurement and a first dielectric constant measurement corresponding to the first interrogation frequency, the second set of data indicative of a second conductivity measurement and a second dielectric constant measurement corresponding to the second interrogation frequency; and (e) assigning values to each of the plurality of admittance parameters to form a specific model for predicting measurements of at least one electrical property of the portion as a function of interrogation frequency, wherein the specific model is consistent with the first and second sets of data and corresponding first and second interrogation frequencies.
