The effects of mobile water saturations on oil recovery and solvent requirements were studied in miscible displacement tests on sandstone cores. Conclusions are as follows. Oil, if trapped by mobile water, cannot easily be contacted by solvent and the amount is directly related to measurable relative permeability characteristics. Miscible displacement performances for secondary and tertiary conditions are equivalent. Long-core tests describe the movement of fluid banks in field-scale floods. Flooding response for solvent developed from multiple contact of crude oil with carbon-dioxide or rich gas in long cores is the same as that for liquid solvents having first-contact miscibility.
