Abstract

Miscibility is controlled by physical dispersion during miscible processes. It comprises of two parameters: diffusion and mechanical dispersion.2 Unfortunately, this parameter is usually ignored during simulating the miscible processes which would be considered as an enormous source of error. Testing different dispersivities on a synthetic model shows the existence of three regions at which each component of physical dispersion controls the miscible displacement in porous media. For dispersivities between 0.73m to 0.83m the miscible process is controlled by physical dispersion mechanism while dispersivities lower than 0.73m specifies a region controlled by diffusion. The third region is the region for dispersivities greater than 0.83m and the main parameter affecting the miscible process in this region is mechanical dispersion. This study also shows that if the miscible process designed to be in transition zone, the highest amount of recovery would be achieved.
