New correlations for CO2-Oil solubility and viscosity reduction for light oils

This paper presents the development of new empirical correlations for (1) CO 2 solubility in dead oil and (2) oil viscosity reduction ratio due to CO 2 saturation. These correlations are specifically developed for light oils, i.e., with oil gravities less than 0.9 (greater than 26° API). The new correlations are developed to be simple equations and dependent only on reservoir temperature and pressure while maintaining a relatively high level of accuracy. The new correlations developed in this work can be used as a tool for better performance evaluation of CO 2 injection into depleted oil fields and/or CO 2 sequestration.
