Phase Behaviour and Physical Properties of Athabasca Bitumen and Solvent Mixtures
Abstract
The production of heavy oil and bitumen is more complex than conventional oil production. One of the main reasons is their high viscosity that must be lowered in order to be recoverable by an oil recovery method such as solvent injection, SAGD, and ES- SAGD.
The objective of this study was to better understanding of phase behaviour and thermo-physical properties of solvent/bitumen mixtures. Our findings will find applications in the design and simulation of heavy oil and bitumen recovery processes.
Solubility of CO2 and N2 in Athabasca bitumen, the density, and viscosity of saturated bitumen were measured at several temperatures and pressures. PR-EoS was applied to represent the experimental solubility data. Density and viscosity of diluted Athabasca bitumen with n-pentane and n-hexane were measured at several temperatures, pressures, and solvent concentrations. Various mixing rules was examined to find appropriate method for predicting the density and viscosity of solvent bitumen system.
