Abstract

Slimtube experiments are used as a determination of Minimum Miscibility Pressure (MMP) for different Enhanced Oil Recovery (EOR) techniques. It is the most reliable technique available for MMP determination. Since slimtube experiments are time consuming, simulation of the process is highly beneficial for fast determination of MMP. This article presents a new set of slimtube simulations to obtain MMP of pure hydrocarbons by CO2. Pure hydrocarbons are subjected to CO2 flooding in slimtube simulationsat different temperatures. Pure hydrocarbons MMP cannot be determined by present correlations used in petroleum industry. At the end, CO2 MMP for each pure hydrocarbon up to C8 is obtained in temperatures varying from 15 to 70°C. As liquid CO2 is also used in these simulations, it showed that by using liquid CO2, the dependency of MMP to molecular weight of hydrocarbon will be decreased and usage of liquid CO2 will yield almost same result for all pure hydrocarbons used in this research.
