  • Determination of Saturation Pressures and Swelling Factors of Solvent(s)–Heavy Oil Systems under Reservoir Conditions
    Industrial & Engineering Chemistry Research, 2014
    Co-Authors: Ping Yang, Daoyong Yang
    Abstract:

    Techniques have been developed to experimentally and theoretically determine saturation pressures and swelling factors of solvent(s)–heavy Oil Systems under reservoir conditions. Experimentally, PVT tests are performed to measure saturation pressures and swelling factors of a C3H8–heavy Oil System and a CH4–C3H8–heavy Oil System under reservoir conditions, respectively. Theoretically, the volume-translated Peng–Robinson equation of state (PR-EOS) together with the modified alpha function has been used to model phase behavior of the aforementioned solvent(s)–heavy Oil Systems. A binary interaction parameter (BIP) correlation has been developed for CH4–heavy Oil Systems based on the literature data. As for the CH4–C3H8–heavy Oil System with a fixed composition, both saturation pressure and swelling factor increase with temperature. The PR-EOS together with the modified alpha function and the newly developed BIP correlation is able to predict the saturation pressures and swelling factors of the CH4–C3H8–heav...

  • Enhanced Swelling Effect and Viscosity Reduction of Solvent(s)/CO2/Heavy-Oil Systems
    SPE Journal, 2013
    Co-Authors: Sixu Zheng, Daoyong Yang
    Abstract:

    Summary In this paper, techniques have been developed to examine the enhanced swelling effect and viscosity reduction of CO2-saturated heavy Oil with the addition of either solvent C3H8 or solvent n-C4H10. Experimentally, pressure/volume/temperature (PVT) tests are conducted to measure the saturation pressure, swelling factor, and viscosity of the C3H8/heavy-Oil System, the C3H8/CO2/heavy-Oil System, and the n-C4H10/CO2/heavy-Oil System, respectively, in the overall temperature range of 280.45 to 391.55 K. It has been found that an increased swelling effect of heavy Oil is obtained by adding the gas solvent C3H8 or n-C4H10 into the CO2 stream. An enhanced viscosity reduction of the CO2/heavy-Oil System is also achieved in the presence of either C3H8 or n-C4H10. The enhanced swelling effect and viscosity reduction caused by adding either C3H8 or n-C4H10 into the CO2 stream are particularly favorable for achieving a higher heavy-Oil recovery compared with pure-CO2 processes. Theoretically, three binary-interaction-parameter (BIP) correlations in the Peng-Robinson (PR) equation of state (EOS) (PR-EOS) method have been proposed for respectively characterizing CO2/heavy-Oil binaries, C3H8/heavy-Oil binaries, and n-C4H10/heavy-Oil binaries by treating each Oil sample as a single pseudocomponent with its molecular weight (MW) and specific gravity (SG). The BIP correlations (together with the PR-EOS) can be used to predict the saturation pressures and swelling factors of the C3H8/CO2/heavy-Oil System and the n-C4H10/CO2/heavy-Oil System with a generally good accuracy.

    All Days, 2013
    Co-Authors: Daoyong Tony Yang, Ping Yang
    Abstract:

    Abstract In this paper, techniques have been developed to experimentally and theoretically study phase behaviour of CH4-C3H8-heavy Oil Systems under reservoir conditions. Experimentally, PVT tests are performed to measure saturation pressures and swelling factors of a C3H8-heavy Oil System and a CH4-C3H8-heavy Oil System under reservoir conditions, respectively. Theoretically, the volume-translated Peng-Robinson equation of state (PR-EOS) together with the modified alpha function has been used to model phase behaviour of the above solvent(s)-heavy Oil Systems. The binary interaction parameter (BIP) correlation is developed for CH4-heavy Oil Systems based on the literature data. As for the CH4-C3H8-heavy Oil System with a fixed composition, both saturation pressure and swelling factor increase with temperature. The PR-EOS together with the modified alpha function and the newly developed BIP correlation is able to predict the saturation pressures and swelling factors of the CH4-C3H8-heavy Oil Systems with average absolute deviation of 11.89% and 2.22%, respectively.

  • Enhanced Swelling Effect and Viscosity Reduction of Solvents-CO2-Heavy Oil Systems
    All Days, 2011
    Co-Authors: Sixu Zheng, Daoyong Tony Yang
    Abstract:

    Abstract In this paper, techniques have been developed to examine the enhanced swelling effect and viscosity reduction of CO2-saturated heavy Oil with addition of rich solvent C3H8. Experimentally, PVT tests are conducted to measure the saturation pressure, swelling factor and viscosity of the C3H8-heavy Oil System and C3H8-CO2-heavy Oil System, respectively. It has been found that an increased swelling effect of heavy Oil is obtained by adding rich solvent C3H8 into CO2 stream. An enhanced viscosity reduction of the CO2-heavy Oil System is also achieved in the presence of rich solvents such as C3H8. Theoretically, two binary interaction parameter (BIP) correlations in Peng-Robinson equation of state (PR-EOS) have been proposed for respectively characterizing CO2-heavy Oil Systems and C3H8-heavy Oil Systems by treating each Oil sample as a single pseudocomponent with its molecular weight and specific gravity. The BIP correlations together with the PR-EOS can be used to predict the saturation pressures and swelling factors of the C3H8-CO2-heavy Oil Systems with a good accuracy. Also, in comparison to other mixing rules, the Lobe’s mixing rule is found to be more appropriate for quantifying viscosity reduction of the heavy Oil with dissolution of CO2 and/or C3H8.
