METHODS OF WELL CLEANOUT, STIMULATION AND REMEDIATION AND THERMAL CONVERTOR ASSEMBLY FOR ACCOMPLISHING SAME
A thermal convertor is formed from a controlled combustion chamber selectively supplied by an appropriate fuel, preferably diesel, and compressed air. The control over the temperature of the combustion chamber is provided by regulating the flow of fuel, air and pressure into and out of the combustion chamber. Flow control valves open or close the inputs of fuel and water to, and the output of the superheated vapors from, the combustion chamber to specifically control the behavior of the combustion chamber and the composition and quality of the output from the combustion chamber. This assembly is then used to inject superheated nearly oxygen-free vapors including well treatment chemicals into a well bore cleaning the well, including the annulus and rathole, near-well bore and perforations of fines and asphaltenic particles, then stimulating an existing but newly cleaned well to produce additional oil. These methods can also be used to stimulate high paraffinic wells or wells with high viscosity crude oil, and for the maintenance of well pressure to enhance production rates.
