| Summary: | The robustness and speed of a flash-calculation algorithm is very important for compositional and compositional thermal reservoir simulation. The two-phase vapor/liquid equilibrium flash calculation algorithm is well developed, but two-phase liquid/liquid equilibrium and three-phase vapor/liquid/liquid equilibrium flash calculation algorithms are not well developed. In this study, a new and robust algorithm for water/oil/gas multiphase flash calculation is developed. Comparisons with experimental data and simulation results from commercial software validate the new algorithm. Also, the new algorithm is used to study water/hydrocarbon mutual solubility effect that is generally ignored in petroleum industry practice. It is unknown how much the water-in-oil solubility effect will influence oil recovery in steam injection processes. In this work, a 3D, fully implicit, fully compositional, thermal reservoir simulator is developed. The simulator considers water/hydrocarbon mutual solubility and is used to evaluate the effect of water-in-oil solubility on oil production in steam-injection processes. Simulation results show that effect of water-in-oil solubility increases oil recovery in both steam huff 'n' puff and steamflooding processes. The new flash calculation algorithm is useful to both petroleum engineering and chemical engineering applications. The reservoir simulator can be widely used to study production mechanisms in steam-injection processes. Also, with some modifications, the reservoir simulator should be capable of modeling gas production from natural gas hydrates accumulations. |
