Assessment and Development of CO2 Minimum Miscibility Pressure correlations for the candidates Libyan Oil Reservoirs

Abstract

The main objectives of this study to apply the published empirical correlation that used to estimate the MMP on different Libyan crude oil that in range 34 to 39 API. Also, the critical objective in our study was to develop a new simple correlation by study the effect of PVT properties in estimation of MMP that can be used to predict the MMP with high accuracy for Libyan crude oils. Minitab regression tool was extensively used in our study and a wide range of new constructed correlations by adding the effect the fluid properties as oil formation volume factor. Sensitivity analysis to study the effect of fluid properties on estimation of MMP by study several cases that related to PVT properties and detect the effect by statistical analysis in each case. The proposed correlation is mainly function of the API, Pb, Pe, μo, Rs, Bo and ρo and has an exactable degree of accuracy (AARE =0.65%, R2 =1.00, SD=539.16 and S=34) and has shown best performance as compared with other published correlations.
