Abstract
Wettability of a solid-liquid-fluid or solid-liquid-liquid system is defined as the ability of one fluid, in the presence of another, to spread on a solid surface. The degree of wetting of a solid by liquids can be quantified, for instance, by measuring the angle of contact that a liquid-fluid interface makes with a solid. However, such measurements are extremely sensitive to the degree of smoothness and composition of the underlying substrate (cf. Chattoraj & Birdi, 1984; de Gennes, 1985). Consequently, contact angles are inefficient as a tool for evaluations of wettability in porous media suffering both from geometrical chaoticity (pore surfaces are a random object) and from chemical disorder (wetting properties may vary from one point to another).
