Interfacial Tension between Water and Oil under Reservoir Conditions

Abstract

The distribution and movement of fluids in oil reservoirs are influenced toa great extent by capillary forces, which depend upon the size and shape of thepores in the reservoir rock, the surface characteristics of the rock, and theinterfacial tension between the fluid phases. This paper presents the resultsof an investigation of the interfacial tension between salt water and crude oilcontaining dissolved gas under reservoir conditions.
