Compared to commonly used F imp correlations in the literature, this new correlation yields a more accurate match to the F imp data found in the literature. For oil samples with molecular weights lower than a certain minimum value ( M min) at various temperatures, a chart has been created for supplying a coefficient in the equation. In this equation, F imp is expressed as a function of the pseudo-critical temperature of the impure CO 2, the critical pressures of CO 2 and N 2, and the reservoir temperature.

Winprop Phase behavior and Fluid Property Program, Version 2013 User Guide. Based on the modeling results, an analytical equation has been developed for predicting the ratio of impure CO 2 MMP to pure CO 2 MMP, F imp. Import the properties along with the simulation grid from CMG dataset files (refer to Importing 3D Simulation Grids and Grid Properties in this manual). Nitrogen diluted CO 2 MMPs for 55 model oil samples were calculated using the Peng–Robinson Equation of State (PR EOS) in the temperature range of 305–360 K. This paper presents a thorough study of the effects of nitrogen on CO 2 minimum miscibility pressure (MMP) for CO 2 storage in depleted oil reservoirs. Injection of CO 2 into depleted oil reservoirs can result in incremental oil recovery to help offset the cost of CO 2 storage.
