It was shown that oil production is highly dependent on how quickly solvent...

... of production rate was not similar to the permeability ratio, indicating the important role of capillary pressure in the gravity drainage mechanism. However, ultimate oil recovery was less sensitive to the matrix permeability at pressures near or above minimum miscibility pressure. The observations were more...

... that insure no bulk flow. However, the pressures of each phase are related by capillary pressure and phase densities. They cannot be specified independently. To do so at the boundary is erroneous. This error can be avoided by choosing boundary conditions that curtail flow through the boundaries...
