Key words: in situ combustion, differential scanning calorimetry (DSC), chemical transformations model (CTM), oil field simulation, in situ oxidation, enhanced oil recovery.

Oil development, which include of oxygen-containing compounds injection, is potentially very perspective. However, to date, hydrodynamic simulation of the in situcombustion is an extremely complex process. This paper provides the method of determining parameters of chemical transformations model (CTM) based on laboratory experiments using high pressure differential scanning calorimeter (DSC). Block diagram of the proposed approach to process the DSC curves is presented. It is given an example of the kinetic parameters of CTM based on processing the real DSK proposed approach and its discussion.
