Thin Films and Fluid Distributions in Porous Media

Investigations of thin-film effects by means of complete solutions of the augmented Young-Laplace equation are summarized, as are the implications for observable contact angle, certain wettability syndromes, and breakup of nonwetting phase as it is replaced in a porous medium by wetting phase. Apparent contact angle, capillary pressure, and thin-film thickness are found to be interdependent at equilibrium: contact angle in porous media may depend significantly on pore size, fluid proportions, and filling history.
