ABSTRACT:
A process for recovering hydrocarbons from a subterranean formation in which in situ combustion is first initiated in the formation by injection of air, for example, through an injection well, the injection of air is terminated, carbon dioxide or nitrogen is injected into the formation via the injection well to displace unconsumed air and in a final step a mixture of carbon monoxide and hydrogen is injected into the formation where reaction of the carbon monoxide with steam generated from the formation water forms additional hydrogen and carbon dioxide and finally hydrocarbons are recovered via a production well.
Optionally, after injection of the mixture of carbon monoxide and hydrogen into the formation has been terminated the heat stored in the formation may be recovered by injecting water as a drive fluid into the formation. The injected water may contain a small amount of a sulfated interfacial tension reducer having, for example, the formula: ##STR1##
