Abstract:
Nuclear magnetic resonance (NMR) gas isotherm techniques to evaluate wettability of porous media, such as hydrocarbon reservoir rock, can include constructing a NMR gas isotherm curve for a porous media sample gas adsorption under various pressures. A hydrophobic or hydrophilic nature of the porous media sample can be determined using the NMR gas isotherm curves. A wettability of the porous media sample can be determined based on the NMR gas isotherm curve. The wettability can be determined for porous media samples with different pore sizes. In the case of reservoir rock samples, the determined wettability can be used, among other things, to model the hydrocarbon reservoir that includes such rock samples, to simulate fluid flow through such reservoirs, or to model enhanced hydrocarbon recovery from such reservoirs.

Claim (Index 16):
The method of  claim 1 , wherein, at each pressure of the plurality of pressures, applying a SE-SPI pulse sequence to the plurality of porous regions distributed along the longitudinal axis of the reservoir rock sample comprises, while applying each pressure:\n applying the SE-SPI pulse sequence to the plurality of porous regions in the reservoir rock sample; and for each porous region, measuring a T2 decay time responsive to the applied pressure.
