Low-Temperature Oxidation Kinetic Parameters for In-Situ Combustion Numerical Simulation

The principal objective of this study was to provide low temperature oxidation (LTO) reaction models which are suitable for use in numeric simulators in in situ combustion for bitumen and heavy oil reservoirs. A systematic study was conducted to investigate the LTO reactions of the liquid phase components of bitumen and heavy oils. Kinetic models are established for the liquid phase reaction components involved in the LTO reactions of a mixture of complex hydrocarbons. Based on the experimental kinetic data, 2 main types of reaction models are proposed. There are (1) a nonsteady state kinetic model to represent the overall rate of oxygen consumption, and (2) 4 nonsteady multiresponse kinetic models representing the oxidation reactions of the liquid phase components. 18 references.
