Charles H Ware, Myron I Kuhlman: Method for producing viscous hydrocarbon using steam and carbon dioxide. World Energy Systems Incorporated, Patterson & Sheridan, January 10, 2012: US08091625 (20 worldwide citation)

A downhole burner is used for producing heavy-oil formations. Hydrogen, oxygen, and steam are pumped by separate conduits to the burner, which burns at least part of the hydrogen and forces the combustion products out into the earth formation. The steam cools the burner and becomes superheated steam ...
