Patent ID: 7171310

Claim:
A method of estimating electrical parameters of an earth formation using a measuring device disposed to be deployed in a borehole, the measuring device disposed to collect formation data, the measuring device having a pre-established model associated therewith, the pre-established model governing the processing of the formation data to determine electrical parameters regarding the earth formation, the method comprising: (a) providing a simplified model associated with the measuring device, the simplified model making at least one simplifying assumption about the pre-established model; (b) receiving a set of collected formation data regarding the earth formation, the set of collected formation data collected by the measuring device; (c) normalizing the set of collected formation data to derive a renormalized dataset, wherein the renormalized dataset is substantially consistent with each of the simplifying assumptions in (a); (d) applying the renormalized dataset to the simplified model to estimate at least one electrical parameter of the earth formation; and (e) using the estimate of the at least one electrical parameter of the earth formation in a manner selected from the group consisting of detecting a hydrocarbon within the earth formation, guiding a drill bit within a productive zone of the earth formation, estimating poor pressure of the earth formation, evaluating geological features of the earth formation, and detecting vertical fractures within the earth formation.
