... Abstract SAGD technology has been applied by scale in Liaohe Oilfield China, where high pressure steam is injected in a horizontal well to drain tight oil into the lower production well. However, much waste heat has not been exploited, including heat of the hot production fluid, flue gas...

... and compact steam and flue gas generator is developed to employ cyclic steam-gas-chemical stimulation, and the whole injection system consists of gas generator, water treatment unit, fuel and chemical tanks, insulated surface pipe and tubing. Steam and flue gas are coinjected at the pressure up to 20MPa...

... like flue gas, oil and water were collected at regular intervals, their composition were measured for monitoring the In-situ combustion process. The increase in CO 2 concentration to the level of 15 %, reduction in oil viscosity and water salinity by half, increase in Well Head temperature and SO 4...
