The effect of displacement rate on imbibition relative permeability and residual saturation

Nguyen, Viet Hoai; Sheppard, Adrian; Knackstedt, Mark; Pinczewski, Wolf Val


A dynamic network model for imbibition based on a physically realistic description of the complex dynamics of film flow, film swelling and snap-off is described. The model shows that film swelling is a capillary driven nonlinear diffusive process and that the competition between snap-off and frontal displacements is rate dependent resulting in rate dependent relative permeability curves and residual saturations. In contrast to existing quasi-static network models where snap-off is suppressed by...[Show more]
