A method for recovering oil from a tilted oil-bearing reservoir having a water zone in fluid communication with and directly below an oil zone wherein a large amount of solvent is injected along the water-oil interface so that a part of the solvent fingers into the oil, lowering its viscosity and making the oil more mobile for production. The remainder of the solvent is driven through the reservoir by a water flood wherein the rate is controlled slow enough that gravity minimizes fingering of the water into the oil layer, sweeping oil toward the production well. Solvent stimulation of the producing well provides additional incremental recovery and encourages the flooded oil toward the production well.
