| titleOfInvention | Vertical downward gas-driven miscible blanket flooding oil recovery process |
| abstract | A vertical downward gas-driven miscible blanket oil recovery process wherein the spreading rate of the solvent blanket on top of the oil column is increased by adding to the conventional solvent a high density solvent such as carbon disulfide, carbon tetrachloride or certain halogenated hydrocarbons. Sufficient dense solvent is added to the conventional hydrocarbon solvent to increase the density of the injected solvent mixture to a value only slightly less than the density of the formation petroleum being displaced, so that a stable blanket will be maintained with substantially increased rate and extent of spreading of the solvent blanket on top of the oil column. The miscible blanket is displaced downward by injecting gas such as natural gas, methane, or carbon dioxide into the upper portion of the reservoir. |
