CPC G01N 24/081 (2013.01) [G01V 3/20 (2013.01); G01V 3/32 (2013.01); G01V 3/38 (2013.01)] | 14 Claims |
1. A method of characterizing tortuosity of a porous media, wherein the porous media is saturated with both a water phase and a hydrocarbon phase, comprising:
using results of at least one NMR measurement and at least one dielectric dispersion measurement performed on the porous media to determine data that characterizes tortuosity of a porous media and data that characterizes tortuosity of fluid phases in the porous media;
wherein the results of the at least one NMR measurement comprises Diffusion D-T2 data of the porous media;
analyzing a part of the Diffusion D-T2 data that is attributable to pores filled with water to determine an NMR-based water phase tortuosity;
determining a dielectric-based water phase tortuosity by inversion of the at least one dielectric dispersion measurement; and
using the dielectric-based water phase tortuosity as data that characterizes water phase tortuosity of the porous media and analyzing a part of the Diffusion D-T2 data that is attributable to pores filled with hydrocarbon to determine hydrocarbon phase tortuosity of the porous media.
