  • Method of oil recovery employing enriched gas drive with control of evolved gas
    Patent number: 4086961
    Abstract: A method for the recovery of hydrocarbons from a subterranean hydrocarbon-bearing reservoir by an enriched gas drive wherein lean gas, evolved from the miscible transition zone, is produced ahead of the miscible transition zone and reinjected behind the solvent injection point whereby excessive gas production is utilized and a drive agent miscible with the solvent is provided to displace the reservoir fluids through the reservoir to a production well from which they are produced.
