Claim 14:
15. The method of claim 13, further comprising:
using the first computational model to generate multiple apparent CEC profiles of the formation from volume fractions of total clay in the formation at multiple well depths, wherein the multiple apparent CEC profiles assume varying amounts or concentrations of the predefined set of clay minerals, and wherein each apparent CEC profile includes apparent CEC values for the multiple well depths in the formation;
using the second computational model and the induction log data of formation to generate a calculated CEC profile that includes calculated CEC values for the same multiple well depths in the formation;
comparing the multiple apparent CEC profiles to the calculated CEC profile to identify a particular apparent CEC profile of the multiple apparent CEC profiles that best matches the calculated CEC profile; and
using the assumed amounts or concentrations of the predefined set of clay minerals for the particular apparent CEC profile to determine the amounts or concentrations of the predefined set of clay minerals in the formation.
