Method for estimating formation lithology
This patent describes a method for estimating formation lithology. It comprises: obtaining measures of a selected formation property along three separate directions in the formation; obtaining a measure of the extent of formation anisotropy from a measure of the difference between the measured formation property along a first pair of directions in the formation; obtaining a measure of the extent of formation anisotropy from a measure of the difference between the measured formation property along a second pair of directions in the formation; and crossplotting the measures of the extent of formation anisotropy along first and second axes on a lithology diagram so as to obtain an estimate of formation lithology.
