NMR IMAGING OF PORE STRUCTURES IN LIMESTONES
Nuclear-magnetic-resonance (NMR) imaging was used to examine pore structures and liquid flow paths in rocks nondestructively. Various pore types were recognized in a spectrum of limestones, including growth-framework, moldic, vuggy, between-particle, and within-particle porosities. Pore connectivity was examined by fluid displacement and flow-weighted and 3D imaging.
