Zusammenfassung:A method for recovering heavy oils and tar sand oils which involves first improving the reservoir permeability without fracturing the reservoir and subsequently flooding the reservoir with hot water or steam. The permeability is improved by establishing some permeability using water injection followed by flooding with an aqueous fluid containing chemical additives which will spontaneously emulsify the oil.
