Abstract
An improved system for using magnetic resonance techniques to obtain information relating to geologic structures. The system of the present invention uses values of bulk-volume irreducible water and porosity obtained via the magnetic resonance techniques to obtain additional information relating to geologic structures, including water saturation.
