STREAMING CURRENT INDUCED BY FLUID FLOW IN POROUS MEDIA

Abstract

Streaming current is induced by the relative motion between a fluid and a solid surface under a fluid pressure difference. In this work, a theoretical model for the streaming current coefficient in porous media is firstly developed based on the fractal theory. The proposed model is then compared with experimental data in the literature and other models. It seems that the prediction from the proposed model is in better agreement with the experimental data than the other models. Therefore, the proposed model may be an alternative approach to predict the streaming current coefficient from the zeta potential, rock parameters and fluid properties. It is also proved that fractal theory is the alternative and useful means for studying the transport phenomenon in porous media.
