Allen, J C

A two-step method 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 and in a final step a combustion-supporting gas such as air, air mixed with oxygen, etc. And a combustible gas such as hydrogen, carbon monoxide and mixtures thereof are introduced into the formation preferably through separate sets of casing perforations and finally hydrocarbons are recovered via a production well.
