Two important parameters involved in the design of surfactant enhanced oil recovery processes are the overall dispersion of the surfactant through the porous media and the permeability of the porous media itself. This study was performed to investigate changes in mass dispersion and permeability that might be caused by the addition of surface active agents. It is shown that surfactant adsorption to the rough surfaces of geological materials such as Berea sandstone has increased interfacial momentum transfer. This is caused by an increase in viscosity near the solid-fluid surface due to an accumulation of surfactant near the interface. Larger velocity gradients in the pore flow-paths increases Taylor dispersion and therefore results in an increase in mass dispersion. |
