Application of PC-SAFT Equation of State to Bitumen/Solvent Systems
Abstract
Solvent-assisted process is promising to recovery Canada's bitumen recourses, but the prediction techniques for the solubility, density and viscosity of bitumen and solvent mixtures in reservoir simulation are not well developed. This thesis works to develop the application methodology of the simplified Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT) to bitumen and solvent mixtures. New binary interaction coefficient correlation and bitumen characterization method are developed to model the solubility, density and viscosity of such mixtures. These results are also integrated into the reservoir simulation of solvent-assisted recovery. Using the developed method, the average absolute relative deviations (AARDs) are 6.6% for the solubility, 2.3% for the density and 14.6% for the viscosity. In addition, the reservoir simulation results indicate good agreement with the sandpack production data using solvents. This thesis has developed the methodology to model the phase behavior and recovery process of bitumen and solvent using PC-SAFT.
