✦ Synopsis

The minimum miscibility pressures (MMP) of a Chinese reservoir crude oil injected with pure and impure CO2 have been measured in a RUSKA slim tube apparatus. New correlations are proposed for CO/-flooding and lean natural gasflooding systems, respectively. The comparisons of the new correlations with several representative MMP correlations available in the literature show that the new correlations give the best prediction results. Based on the cell-to-cell algorithm proposed by Jensen and Michelsen, minimum misibility pressures for various gas-flooding processes were predicted using an equation-of-state and a semicontinuous description of heptane-plus fraction. Satisfactory results were obtained.
