Abstract
Techniques involve obtaining dielectric measurements measured from a dielectric logging tool investigating a borehole at a one or more frequencies in a first frequency range, obtaining inductive measurements measured from an inductive tool investigating the borehole at one or more frequencies in a second frequency range, where the second frequency range is higher than the first frequency range, estimating an estimated resistivity anisotropy by conducting an inversion on the dielectric measurements, computing a measured resistivity anisotropy by conducting an inversion on the inductive measurements, and determining a characteristic related to reservoir fluids in the borehole, based on a comparison of the estimated resistivity anisotropy and the measured resistivity anisotropy.
