Gas Contribution to Green House Effect
Gas Based EOR ProcessMiscible & immiscible gas injection processIn miscible gas injection process mass transfer occur betweenoil & gas & forms a transition zone to displace the oil effectively.ely.Miscible gas injection gives better displacement efficiency.Immiscible gas injection improves recovery by swelling & oilviscosity reduction.Displacement efficiency of immiscible gas injection is less thenmiscible gas injection process.
