ABSTRACT:
An improved system for using magnetic resonance techniques to obtain information relating to geologic structures is disclosed. The system of the present invention uses values of the total porosity of a formation and the porosity obtained via NMR pulse echo techniques to derive additional information relating to the underlying geologic structures, including resistivity and water saturation. Independent estimate is provided to account for the presence of clay mineral content.
