Abstract
A method of oil production after water flooding includes the steps of: forming at least one injection well and at least one production well in a reservoir; pumping enriched air (at least 30-100 mole-% oxygen with fogged water droplets) into the injection well, so as to maximize gravity segregation of gas/steam and gravity drainage of oil from an attic and/or pinch-out volume of the reservoir; and recycling produced carbon dioxide by injection into a man-made gas cap created around the at least one injection well. The enriched air preferably includes a mixture of 30-100 mole-% oxygen, 0-4 mole-% argon, 0-67 mole-% nitrogen and 0-70 mole-carbon dioxide gas.
