Carbon dioxide miscible flooding has become one of the important technologies for improving oil recovery. The Minimum Miscible Pressure (MMP) is key parameter to realize flooding. As MMP in research area higher than formation fracture pressure, cannot be formed. To address this problem, it necessary find a way reduce MMP. Citric acid isobutyl ester chosen carbon and crude research. effect citri...

Abstract Low oil recovery which is very predominant in shale reservoirs has stimulated petroleum engineers to investigate the applications of enhanced methods these formations. One such application injection gases into formation stimulate increased recovery. In many gas flooding projects performed field, miscibility injected usually most desired displacement mechanism, and carbon dioxide (CO 2 ...
