Low-field nuclear magnetic resonance techniques were applied to quantitatively characterize tortuosity in heterogeneous carbonate rocks by measuring diffusion coefficients of bulk and confined methane. A novel application of a simultaneous Gaussian and exponential data inversion was used to characterize bitumen content and capillary trapped water within shale rock cores at various relative humidity conditions. Furthermore, ethane adsorption capacities in model mesoporous silicas at various pressures were quantitatively characterized. Finally, new insights into the quantitative characterization of gas adsorption capacities in shale rock cores were obtained by utilizing an NMR-based material balance approach.
