Gas Based EOR ProcessHydrocarbon Miscible Flooding :Hydrocarbon miscible flooding consists of injecting lighthydrocarbons through the reservoir to form a miscible flood. Theprocess recovers crude oil by generating miscibility (in thecondensing and vaporizing gas drive), increasing oil volume byswelling and decreasing the viscosity of oil. Three different methodsof attaining miscibility are used. One method uses about 5% PV slug sof liquefied petroleum gas such as propane, followed by natural gasor gas and water. A second method called enriched (condensing)gas drive , consists of injecting 10 to 20% PV slug of natural gas gthat is enriched with ethane through hexane(C2 to C6) , followed bylean gas and possible water.
Gas Based EOR ProcessOverall displacement EfficiencyE = Es x Ei x EdWhere Es is areal sweep efficiencyEi is invasion efficiency or vertical sweep efficiencyEd is microscopic displacement efficiency which accounts for thetrapping of oil by capillary forces in the pores invaded bydisplacing fluid.
