In order to model the in-situ superwet combustion method for enhanced oil recovery, key phenomena of the superwet combustion reaction and the reaction rate were investigated. Firstly, a batch type reactor was used to investigate phenomena related to the wet oxidation reaction in case of a limited oxygen supply. It was found that (1) a notable change of oil in quality did not occur, (2) acetic acid was the major intermediate product with minor products of acetones and ketones as well as other carboxylic acids, (3) water-soluble intermediate products did not significantly lower the interfacial tension with oil, and (4) 40 percent of oxygen supply was consumed to produce carbon oxides.Secondly, a continuous flow reactor was used to obtain reaction rate equations for wet oxidation. Experiments were carried out with a sand pack as a reactor, using injection gases of different oxygen concentrations, at temperatures ranging from 200 to 275°C. It was found that the reaction order for oxygen concentration was unity, and the activation energy was 85.6 kJ/mol. Furthermore, the rate equations for the oil consumption and the heat of combustion were derived on the basis of the rate equation for oxygen consumption.
