CO2 MMP determination on L Reservoir by using CMG simulation and correlations

Abstract

CO₂ minimum miscibility pressure (MMP) is an important parameter in CO₂ enhanced oil recovery (CO₂-EOR) process. The CO₂ injection must be conducted at the pressure equal or greater than MMP. The aim of this study is to determine CO₂ MMP by using one-dimensional CMG simulation model and CO₂ MMP correlations on L reservoir. To make an accurate simulation model and to choose the most satisfying correlation, it is necessary to validate by comparing the obtained CO₂ MMP with experiments in the laboratory on eight type oil from various fields. The result showed that Zhang’s correlation is the best correlation which have -13.9% average percentage of errors while using the CMG simulation model shows the average percentage errors approximately -6.5 %. Using Zhang’s correlation, CO₂ MMP on L reservoir is about 3166 psia and from CMG simulation, CO₂ MMP equals to 3219 psia.
