Michel Gondouin: Heavy oil recovery process. S Cal Research, November 17, 1987: US04706751 (297 worldwide citation)

Heavy oil is recovered from deep reservoirs by injection of a gaseous mixture containing hydrogen, steam and in some cases oil soluble gases and/or vapors. This mixture is produced by a reversible exothermic catalytic reaction in a down-hole reactor and injected into a well drilled, preferably horiz ...
