Abstract

Combustion gases with relatively high levels of carbon dioxide (CO), steam, and/or hot water, may be used to improve recovery of heavy hydrocarbons from geologic formations and/or from surface mined materials. These gases reduce the viscosity and/or increase hydrocarbon extraction rates through improvements in thermal efficiency and/or higher rates of heat delivery for a given combustor an capital investment. Such high water/COcontent combustion gases can be formed by adding water to combustion gases formed by burning fuel. The pressure to inject the combustion gases and extract heavy hydrocarbons may be provided by diverting high pressure expanded gases from wet combustion in a gas turbine, or by reducing the pressure drop across a turbine and using the expanded hot gases for extraction.
