Sklar, I; Walker, G W

A method is described for producing hydrocarbons from a subterranean formation by moving through it an in-situ combustion front between input and output wells. Formation fluid is displaced toward each output well. When directional movement of the front, which may be monitored, will displace formation fluid beyond the drainage radius of an output well, steam is injected. Steam injection may be repeated until of such quantity as to increase the flow of formation fluid from the output well sufficiently to correct directionally the movement of the front for displacing greater amounts of formation fluid into the drainage radius of this output well. Hydrocarbons are recovered from the fluid produced from the output wells. (17 claims)
