A method for determining at least one characteristic of a geological formation having a borehole therein may include collecting first and second dataset snapshots of the geological formation from the borehole. The method may further include generating a differential dataset based upon the first and second dataset snapshots, determining a multi-dimensional space based upon the differential dataset, and generating a first hybrid dataset based upon the first dataset snapshot by projecting the measurement data from the first dataset snapshot parallel to the multi-dimensional space and onto a complementary multi-dimensional space not parallel to the multi-dimensional space. A second hybrid dataset may also be generated based upon the second dataset snapshot by projecting the measurement data from the second dataset snapshot parallel to the same multi-dimensional space and onto the same complementary multi-dimensional space, and the characteristic(s) associated with the geological formation may be determined based upon the first and second hybrid datasets.
