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 21):
A method comprising:\n constructing a nuclear magnetic resonance (NMR) gas isotherm curve for a rock sample in response to, for a plurality of pressures applied to the rock sample, applying a NMR pulse sequence to a plurality of porous regions distributed along a longitudinal axis of the rock sample at each pressure of the plurality of pressures, wherein the plurality of porous regions have a respective plurality of wettabilities, each wettability representing a quality of each porous region to absorb a gas; and determining the plurality of wettabilities for the plurality of porous regions based on the NMR gas isotherm curve, each wettability of the plurality of wettabilities including a value representing the quality of each porous region to absorb the gas; and providing the plurality of wettabilities for the plurality of porous regions.
