Abstract
Solvent assisted recovery processes have taken significant attention recently. It has been shown that co-injection of solvent and steam can increase bitumen production to a rate higher than steam injection alone. The major shortcoming in this area is the lack of basic knowledge relevant to the solvent/heat assisted recovery processes. The objective of this project is to develop an understanding of the phase behaviour of bitumen/solvent systems with four milestones. First, a phase behaviour model based on the Peng-Robinson equation of state has been developed and validated for simple systems. Second, the available mixing rules for computing the co-volumes of polar and non-polar mixtures were evaluated. Third, bitumen was characterized in order to estimate its critical properties based on the boiling point distribution from the simulated distillation data. The boiling point distribution was modeled using probability distribution functions. Finally, the results for the phase behaviour of solvent (e.g. methane, ethane and carbon dioxide)/bitumen (Athabasca, Cold Lake) systems were modeled with an EoS for different operating conditions.
