Abstract
A porosity model of a core sample obtained from a subterranean formation is determined. The porosity model includes a macroporosity group and a microporosity group. A nuclear magnetic resonance (NMR) measurement is performed to obtain an NMR Tdistribution of the core sample at 100% water saturation. A desaturation step is performed on the core sample. An NMR measurement is performed for the desaturation step to obtain an NMR Tdistribution of the core sample. A resistivity index of the subterranean formation is determined at least based on the porosity model and each of the NMR Tdistributions.
