Representing Fluid-Phase Behavior
The key to the attractiveness of miscible gas flooding compared with immiscible flood technologies is interphase mass transfer. Under the right conditions of pressure, temperature, and composition, the exchange of species across the phase boundary in a miscible gas flood leads to the formation of a zone in which the displacing fluid and the displaced fluid are very similar. As described in Section 1.1, the rock swept by such a zone has very low residual oil saturation, implying more efficient oil recovery overall.
