New Dimensionless Model for CO2 Miscible Flooding in Five-Point Scheme

Combining with five-point analytical velocity field, a new and practical CO2 miscible streamline model is developed for five-point pattern. At first, we develop one dimensionless model for CO2 miscible flooding along streamline axis; second, we deduce five-point pattern analytical velocity solution; third, we put driving model and analytical solution into allegiance. Finally, we validate our model through comparison with Eclipse and point out defects of the commercial software.
