| Summary: | along with a commercial PVT simulator are used to tune assuming that the equilibrium ratios, K-values, are zero. In calculations. Viscosity as a function of temperature and composition was modeled with the Pedersen correlation for compositional effect s due to heat and steam and assumed that dimensional numerical simulations of the steamflooding equation-of-state (EOS) and viscosity parameters to properly equation-of-state (PR-EOS) was used for all phase behavior fluid description was developed for the heavy oil, one- generally been conducted assuming that the oil is non- heavy oils. Once a tuned equation-of-state, compositional however, compositional effects need to be taken into account. In this study, laboratory data including distillation, vapor model the PVT properties of the oil. The Peng-Robinson order to properly model the mechanism of steamflooding, pressure, steam distillation and viscosity measurements, process were performed. These simulations demonstrated the steam-oil interface. the field and the formation of an in-situ solvent bank at the the hydrocarbon phase is non-volatile. This is equivalent to The numerical simulation of heavy oil steamfloods has the proper modeling of low residual oil saturations seen in utility of the equation-of-state approach. In addition, it volatile. Reservoir simulation has traditionally ignored was concluded that compositional effects are essential for |
