An in situ combustion process is utilized to extract hydrocarbons from a subterranean oil formation. The process includes injecting a foaming agent solution into the formation via an injection well that penetrates the oil formation, injecting an oxygen containing gas into the formation via the injection well and facilitating a combustion reaction between oxygen and hydrocarbons within the formation. The combustion gases formed by the combustion reaction force the flow of hydrocarbons within the formation. Hydrocarbons that are displaced within the formation are extracted from the formation via a production well that penetrates the formation.
