ABSTRACT:
A novel method of geophysical exploration is described for obtaining estimates the formation lithology from measures of formation anisotropy. First and second measures of formation anisotropy can be transformed into estimates of formation lithology by crossplotting them onto a lithology diagram. In one embodiment of the present invention, the lithology diagram comprises two separate axes representing measures of formation azimuthal anisotropy and transverse isotropy for a selected formation property which defines regions of separate lithologies. The lithology diagram can provide a novel means for discriminating formation lithology from the measures of formation anisotropy.
