Abstract
A conductivity model is used for a logging tool and surrounding borehole and formation. The conductivity model is separable into a background conductivity model and an anomalous conductivity model for at least one of the formation and the tool. With the conductivity model, background electromagnetic fields and Green's functions corresponding to electromagnetic field signals at one or more receivers are computed for inversion of measured electromagnetic signals to determine adjustable parameters associated with anomalous conductivity. From the inversion, dielectric and other electromagnetic properties of the formation and borehole are determined.
