Abstract
A method and apparatus for stimulating a subsurface, oil-bearing reservoir, in which a fuel is burned in the presence of a combustion-supporting gas to produce an essentially uncontaminated flue gas at a pressure significantly above the reservoir pressure, water is intimately mixed with the flue gas, the water is vaporized to produce a mixture of flue gas and steam and the operating parameters of the water vaporization and, particularly, the fuel combustion are controlled by passing the mixture of flue gas and steam through an iris-type shutter having a variable diameter opening and varying the diameter of the variable diameter opening.
