George A. Virnovsky, Arild Lohne, Hans Kleppe · 2002
In a heterogeneous reservoir containing 2 liquid phases, e.g., oil and water, the flow rate in combination with small to medium scale heterogeneities in both absolute permeability and capillarity defines dynamic capillary entrapment of oil and water.
