A knowledge of the effect of CO{sub 2} upon the properties of a hydrocarbon mixture is essential to evaluate how viscous fingering, gravity segregation, hydrodynamic dispersion, and interfacial tension phenomena affect the local displacement efficiency in a miscible gas flooding process. Kinematic viscosities of twelve mixtures made from pentane, hexane, heptane, octane, decane, and carbon dioxide were measured using a rolling ball viscometer. The temperatures ranged from 310 K to 403 K and the pressures from 0.8 MPa to 12 MPa. Kinematic viscosities were converted to absolute viscosities using mixture densities estimated from a modified Rackett equation. Calculated absolute viscosities for the decane + CO{sub 2} system were within 0.5% of the values by Cullick and Mathis. All viscosities of hydrocarbon mixtures and hydrocarbons with CO{sub 2} could be predicted from the Orbey and Sandler correlation with an average absolute deviation of 4.1%. The authors found that the Lohrenz, Bray, and Clark viscosity correlation cannot be used to estimate the viscosity of the mixtures containing CO{sub 2} with reasonable accuracy.
