ABSTRACT:
A method for determining total clay content of an earth formation based on elemental concentration logs obtained from a logging tool. This method avoids the need for obtaining an aluminum concentration measurement. First, the concentrations of a plurality of elements in the formation are determined without measuring an aluminum concentration. Then, at least the silicon, calcium, and iron concentrations are combined in accordance with a function determined by regression analysis to produce an estimate of the total clay content.
