Oil recovery process
Patent
·
OSTI ID:6178279
A miscible flooding process is described for the recovery of oil from an oil-bearing reservoir. A gaseous hydrocarbon solvent which is gaseous at reservoir conditions and which is capable of forming a zone having no discernible phase change with the reservoir oil, is injected into the reservoir via an injection well. This is followed by the injection of a dry gas to move the previously injected gaseous hydrocarbon solvent through the reservoir thereby displacing the oil of the reservoir to a production well from which it is produced.
