Key words: in situ combustion, differential scanning calorimetry, Arrhenius equation, upscaling.
In the present work crude oil oxidation mechanism due to in-situ combustion EOR technology is investigated. The oxidation kinetics’ data from calorimetric experiments is expressed in terms of the Arrhenius kinetic approach; the reaction parameters are estimated by several independent methods and used for the reaction model formation. The kinetic reaction model, including kinetic parameters approximation to the reservoir pressure is presented. The model is adjusted in accordance with the kinetic experimental curves.
