ABSTRACT:
In a combustion process for recovering hydrocarbons from a subterranean formation vertically traversed by an injection well through which an oxygen-containing gas is injected and a plurality of production wells through which liquid hydrocarbons and gaseous products of combustion are produced; oil recovery is improved by throttling of the production wells to increase the steam pressure in the locus ahead of the combustion zone, and according to a preferred mode, the combustion front advance is controlled by selectively throttling and increasing the gas pressure of production wells in the vicinity of the greatest advance of the combustion front.
