Claim Text:
1. A method for characterizing wettability of a porous media, the method comprising: Receiving pore size distribution data representing a distribution of pore sizes within the porous media; Receiving nuclear magnetic resonance (NMR) data from a bulk aqueous fluid; Receiving nuclear magnetic resonance (NMR) data from a bulk oil; and performing an inversion on the nuclear magnetic resonance (NMR) data using a forward model for pore level distribution of wettability and saturation in mixed wet conditions over a plurality of pore sizes using the pore size distribution data and the nuclear magnetic resonance (NMR) data for the bulk aqueous fluid and bulk oil, thereby generating a wettability profile across a pore spectrum for the aqueous and/or oil fluids over a plurality of pore sizes of the porous media.
