• Differences among the results of various approaches are about –5.9% to 3.9%.
• Disagreement among the results is probably caused by different oil sample properties.
• MMP can be estimated by a swelling test only if the extraction stage occurs.
• Causing less CO2 to dissolve in oil, increasing temperature will increase MMP.
This paper presents the results of slim tube experiments and swelling tests on estimating the minimum miscibility pressure (MMP). Previous researchers attempted to relate the two experimental works in obtaining the MMP but failed to achieve the same results. This study attempts to identify such a relationship through a plotting technique of the swelling tests data. In this case, the MMP is graphically determined at the intersection between condensation–extraction and extraction curves. It is found that the two experiments result in the MMP that are very close to each other. In addition to the experimental works, this study also performs numerical simulation and visual observation during the experiments. It is revealed that the differences between the results of the swelling test and those of the slim tube experiments and the simulation are approximately −1.2% to 3.9% and −4.5% to −5.9%, respectively. It then follows that the proposed method provides satisfactory estimates of the MMP.
