A method for recovering heavy and bitumen oil from a subterranean formation 18 and comprises the steps of providing a fuel, burning the fuel in a flue gas recirculation circuit 12 to produce a flue gas for injection into the subterranean formation and injecting the flue gas into the formation to displace the heavy oil and bitumen. The flue gas may be modified prior to injection by the removal of by-products such as hydrogen, carbon monoxide, nitrogen, sulfur and carbon dioxide gas and particulates. Later embodiments relate to a method for recovering gas and bitumen from at least one of a steam assisted gravity drainage formation containing gas 25 over bitumen. |
