“…For instance, the measurements for ethane/bitumen mixtures by Nourozieh (2013) and methane/bitumen mixtures show that the density of the saturated-liquid phase decreases with pressure at a constant temperature. For mixtures that contained CO 2 , however, previous research shows an increase in density with increased CO 2 concentration.…”

The addition of hydrocarbon or nonhydrocarbon gases to steam can have a beneficial effect on the performance of steam-based processes for recovery of heavy and extraheavy oils. The performance of these newly developed techniques depends on the amount of solvent dissolved in the oil and the variation of oil viscosity with temperature. Thus, full understanding of the quantitative effects of the solvent on heavy-oil viscosity and phase behaviors is crucial for feasibility studies, design, and prediction of fieldscale processes.Thus, the aim of this research is the development of an understanding of the phase behavior of carbon dioxide (CO 2 )/Athabasca-bitumen mixtures. It includes both experimental and modeling studies of solubilities and saturated-liquid densities and viscosities over a wide range of temperatures (up to 200 C), approaching the conditions of in-situ steam processes and pressures up to 6 MPa.Experimental results indicate that the dissolved gas in bitumen leads to a significant oil-viscosity reduction, and the effect is greater at lower temperature and higher pressure. The gas-saturated-bitumen densities change slightly with the dissolution of CO 2 . The modeling results show that the measured solubilities are represented adequately by the modified Peng-Robinson equation of state (Robinson and Peng 1978), with an average absolute relative deviation (AARD) of 7.5%. The saturated-liquid densities are also correlated with equation-of-state and effective-liquid-density approaches, with 0.77 and 0.41% AARDs, respectively. The viscosity data are reasonably matched with the modified Pedersen corresponding state (Pedersen and Fredenslund 1987).

“…Fu et al [5] reported ethane solubility in Cold Lake bitumen at temperatures up to 423.15 K. A comprehensive dataset for ethane-bitumen system was presented by Nourozieh. [8] The ethane solubility, viscosity, and density of the bitumen-rich phase were reported at temperatures up to 463.15 K for three bitumen samples from the Athabasca reservoir in Alberta. The dashed line in Figure 1a represents the typical range of thermal recovery methods such as SAGD.…”

Solubility of light n-alkanes in bitumen as well as density and viscosity of the bitumen-rich phase are the necessary data for simulation and study of the solvent-aided thermal recovery processes of bitumen. This paper presents experimental data for MacKay River bitumen with n-alkane solvents (methane, ethane, propane, and butane). The viscosity and density of the solvent saturated bitumen phase are measured to determine the effect of solvent dissolution on the thermo-physical properties of bitumen. The solvent-bitumen system is modelled using the Peng-Robinson equation of state (PR-EoS). Moreover, experimental viscosity and density data of solvent-saturated bitumen are correlated. The effective density and viscosity of the dissolved solvent molecules are obtained using the experimental density and viscosity data for the bitumen-solvent system.

The heavy-oil-and bitumen-recovery processes mainly intend to reduce the oil viscosity at the reservoir; therefore, the production and pipeline transportation of such viscous fluids require specific data on the viscosity and density of raw bitumen. In this study, the thermophysical properties of Athabasca bitumen were reported over a wide range of temperatures and pressures applicable for both in-situ-recovery methods and pipeline transportation of oil. The measurements were taken with our designed phase-behaviourexperimental apparatus, capturing the density and viscosity of Athabasca bitumen accurately at temperatures varying from ambient temperature up to 200 C and at pressures up to 10 MPa. The experimental density data for bitumen were correlated within 60.7 kg/m 3 with a newly developed algorithm to obtain the coefficients of correlation equations, considering the influence of pressure and temperature on the density. The viscosity data are correlated reasonably (within 69%) over the studied conditions with two correlations, which include two adjustable parameters each.
