An integral inequality for the Helmholtz free energy is used to predict the stable, static positions of a fluid-fluid interface in a sinusoidal pore as a function of pressure drop. Washburn's equation is generalized to explain the relative effects of the interfacial viscosities, interfacial tension, and wetting during displacement through such a pore. The limits on the creeping motions between Haines jumps are approximately identified with the limits of static stability. The predictions of a prior qualitative theory for the relative effects of the interfacial viscosities and of interfacial tension during tertiary oil recovery are fully supported. Further, the interfacial dilatational viscosity is indicated to be relatively more important than the interfacial shear viscosity. 41 references, 10 figures.
