In a system with two
immiscible fluids in
contact with a solid, the difference in the two fluid-solid surface tensions. In thermodynamic equilibrium this difference is equivalent as a result of the Young-
Laplace equation to the product of the interfacial tension between the two fluids and the cosine of the contact angle at the fluid/fluid/solid interface. As the combination of these two individual interfacial terms, adhesion tension is a useful measure of the wetting character of a
petroleum reservoir's
pore system.
