The SARA fraction scheme is proposed. The advantages of SARA analysis are identified. SARA fractions correspond to physical fractions of bitumen, so its fluid properties can be estimated for numerical modeling. It allows for simulation of heavy oil other than Athabasca’s, since the procedure to separate crude oils in SARA fractions has been standardized by ASTM. It makes it possible to simulate not only heavy oils and bitumen but also light oil and medium crude oils with the same kinetic model.
Models based on Maltenes and SARA fractions are presented respectively. Specific numerical simulation procedure is also given. It is concluded from numerical simulation results that the correlated model can be incorporated into numerical simulations of the ISC process, which will aid to obtain more reliable and realistic predictions; the kinetic parameters for the reactions can be used as the reference value when studying the chemical nature of liquid phase oxidation of heavy hydro-carbons.
