Comprehensive analysis on thermal and kinetic aspects of in-situ combustion: Numerical approach

In-Situ Combustion (ISC) thermal Enhanced Oil Recovery (EOR) methods are aimed at increasing the oil recoveries of heavy oil reserves that are expected to play an instrumental role in near future in meeting the world's energy demand. The complex multiphase heat and reactive mass transport necessitate a clear understanding of thermal and kinetic models used in modeling of ISC process. A finite difference based numerical analysis is carried out on heat loss and selective productions of light oil components during ISC, which showed a significant effect on peak temperature, thermal front propagation and the corresponding production rates dictating the performance of ISC process. © (2014) Trans Tech Publications, Switzerland.
