INTEGRATED SYSTEM AND METHOD FOR STEAM-ASSISTED GRAVITY DRAINAGE (SAGD)-HEAVY OIL PRODUCTION USING LOW QUALITY FUEL AND LOW QUALITY WATER
First Claim
1. The process for producing steam for extracting heavy bitumen comprising:
- mixing a low quality fuel with an oxidation gas, said fuel selected from the group consisting of crude oil, VR, asphaltin and coke, said oxidation gas selected from the group consisting of oxygen, oxygen-enriched air, and air;
combustion the mixture under high pressures and temperatures; and
mixing low quality water containing organic or inorganic so as to control combustion temperature and to generate steam.

Abstract
A process for producing steam for extracting heavy bitumen includes the steps of mixing carbon or hydrocarbon fuel said fuel being crud oil, VR, Asphaltin, or coke with an oxidation gas, said gas being oxygen, oxygen enriched air or air-combusting the mixture under high pressure and high temperature and mixing low quality contaminated water containing organics and inorganic with the combusted mixture so as to control combustion temperature and to generate steam. The liquid phase is transferred to a gas phase so as to contain steam and carbon dioxide. The solids are separated from the gas phase. The super heated dry steam and gas mixture is ejected into an underground reservoir.
