Abstract
The results of the minimum miscibility pressure (MMP) determination for miscible injection of CO2 and an associated gas of one of Iranian gas reservoirs into two different oil samples using a slim tube device are presented. For an effective determination of the MMP cell-to-cell slim tube simulation was performed for each case before performing the slim tube experiment and the results were used to determine the pressure intervals in the slim tube experiment. A comparison between the measured MMP values from the slim tube experiments and those calculated by cell-to-cell simulation revealed that the cell-to-cell simulation can be a substitute to slim tube test in cases where time is a primary...

Abstract
An algorithm has been developed to investigate the effect of asphaltene precipitation on calculation of minimum miscibility pressure (MMP), which is one of the key design parameters of any gas injection projects. In fact, this algorithm is the extension of procedure suggested by Jaubert et al. for prediction of MMP whatever the displacement mechanism. The vapor-liquid equilibrium calculation and then liquid-liquid equilibrium calculation are required to be taken account to estimate the amount of asphaltene precipitation. The association equation of state (AEOS) has been applied to determine the phase behavior of asphaltene. The algorithm has been used for the MMP prediction of Weyburn...

Abstract
Minimum Miscibility Pressure (MMP) is regarded as one of the foremost parameters required to be measured in a CO2 injection process. Therefore, a reasonable approximation of the MMP can be useful for better development of injection conditions as well as planning surface facilities. In this study, the impact of asphaltene content ranging from 3.84 % to 16 % on CO2/heavy oil MMP is evaluated. In this respect, slim tube miscibility and Vanishing Interfacial Tension (VIT) tests are used. Regarding the VIT test, the Interfacial Tension (IFT) is measured by means of two methods including pendant drop and capillary apparatuses, and thereafter the MMP measurement error between slim tube and VIT...
