Abstract: A well-logging method for a geological formation having a borehole therein may include collecting a plurality of nuclear magnetic resonance (NMR) snapshots from the borehole indicative of changes in the geological formation and defining NMR data. The method may further include identifying a plurality of fluids within the geological formation based upon the NMR data, determining respective NMR signatures for the identified fluids based upon the NMR data, determining apparent volumes for the identified fluids based upon the NMR signatures, and determining adjusted volumes for the identified fluids based upon the apparent volumes.

Abstract: 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.

Abstract: A method for determining compositional data for fluids within a geological formation having a borehole therein may include collecting first and second dataset snapshots of the geological formation based upon measurements from the borehole at respective different first and second times, and with the borehole subject to fluid injection between the first and second times to displace fluids in the geological formation adjacent the borehole. The method may further include generating a differential dataset based upon the first and second dataset snapshots, normalizing the differential dataset to generate a normalized differential dataset, determining vertices defining a geometric shape and corresponding to respective different displaced fluid signatures based upon the normalized differential dataset, and determining displaced compositional data with respect to the different displaced fluid signatures based upon a position of a datapoint from the normalized differential dataset on the geometric shape.
