In a combustion process for recovering hydrocarbons from a subterranean hydrocarbon-bearing formation comprising an upper permeable hydrocarbon-bearing stratum overlying a lower permeable hydrocarbon-bearing stratum and separated therefrom by a semi-permeable stratum which is substantially permeable to oxygen but not substantially permeable to water; the strata are traversed by injection and production wells, the lower hydrocarbon-bearing stratum is ignited near an injection well and oxygen-containing gas is injected into the lower hydrocarbon-bearing stratum to combust hydrocarbons near the injection well and form a combustion front, an oxygen-containing gas is injected into the lower hydrocarbon-bearing stratum and an aqueous fluid is injected into the upper hydrocarbon-bearing stratum to move the combustion front between the injection and the production wells and to prevent or mitigate channeling through the upper hydrocarbon-bearing stratum, and hydrocarbons are recovered from the strata.
