Claim 3:
4. The method of claim 1, wherein the first NMR measurement is 1H T1-T2 2-dimensional correlation map measured with low-field and/or intermediate-field NMR and the correlation is between the NMR signal to fluid volume calibration and an area under the 1H T1-T2 2-dimensional correlation map for one selected from the group consisting of 0.1 ms≤T2<1.5 ms for the nanopores, 1.5 ms≤T2<30 ms for the micropores, 30 ms≤T2<300 ms for the macropores, and any combination thereof.
