A Simple Computational Method to Estimate Minimum Miscibility Pressure (MMP) for CO2 Enhanced Oil Recovery (CO2 EOR) |
| 초록 |
A computational method to estimate MMP for CO2 EOR is developed based on thermodynamic calculations to describe phase behavior of CO2-crude oil multicomponent mixture. Thermodynamic analysis provides fast and effective tools to predict the miscibility of CO2 and crude oil mixtures, which is measured by time-consuming experiments. We suggest that MMP at a reservoir temperature should correspond to the Upper Critical Solution Pressure (UCSP) at the given temperature. Since MMP is a critical property of a multicomponent mixture, its accuracy depends on the robustness of the equation of state used to model the phase behavior near the critical pressure and temperature. In this study, Predictive Peng-Robinson equation of state (PPR78 EOS) is used, where binary interaction parameters (kij) are temperature-dependent, and it lead to better approximations to phase behaviors of real mixtures. The MMP estimation based on composition data and the reservoir temperature showed a good agreement with experimental slim-tube test results within average error of 5%. |
