This paper provides experimental evidence for the validity of the new CT method by comparing the results with previous studies and presents an application of the method to investigate the MMP of the CO 2/n-decane system in porous media. The image intensity values taken from the CT images have a linear relationship with the densities of the measured objects therefore, we can estimate the miscible point of CO 2 and n-decane because the difference between the intensity values for each phase decays to zero as the pressure increases toward the MMP. CT scans of the CO 2/n-decane system are taken at various pressures during the experiments. This paper presents a new technique to investigate the phase behavior and to estimate the minimum miscibility pressure (MMP) of a CO 2/n-decane system using an X-ray computerized tomography (CT) scanner. Accurate determination of gasвЂ“fluid miscibility conditions is important to optimize the displacement efficiency during CO 2-enhanced oil recovery.
