Abstract
A downhole steam-generating system in which fuel and compressed air from an air compressor unit 20 are fed to a steam generator 22. Steam and/or combustion products are fed to the turbine 24 from the steam generator 22 and the turbine 24 is used to mechanically drive the air compressor unit 20. After leaving the turbine 24, the turbine output may be scrubbed and the combustion products may be either passed down the borehole with the steam or may be discharged into the atmosphere.
