With the increasing oil demand, more attention has been paid to enhancing oil recovery in old oil fields. CO 2 flooding is popular due to its high oil displacement efficiency and ability to reduce greenhouse gas emissions. Laboratory experiments and on-site application cases have shown that the minimum miscibility pressure has a greater impact on CO 2 flooding than other factors. If the reservoir pressure is below the minimum miscible pressure, then there is CO 2 immiscible flooding. Both theoretical analysis and experimental results show that the recovery rate of CO 2 miscible flooding is 2−5 times higher than that of immiscible flooding. If the reservoir pressure is increased by water flooding before CO 2 injection, it is easily limited by the physical property parameters. Therefore, accurately determining and effectively reducing the minimum mixing pressure has become the focus of research. Currently, there are two types of methods for determining the minimum miscible pressure: experimental and theoretical methods. The experimental method is generally considered more accurate, including the slim tube test, rising bubble apparatus, and vanishing interfacial tension, etc. However, it is worth noting that the minimum miscibility pressure is dynamically changing, and there will be high economic costs if measured repeatedly through experimental methods during reservoir development. Therefore, it is recognized that the minimum mixing pressure can be determined at any time using theoretical calculation of initial data, which will reduce economic and time costs to a high degree. In this paper, the theoretical calculation method is divided into empirical correlation, state equation, and artificial intelligence algorithm. The techniques for reducing the minimum miscibility pressure can be classified into two categories: miscible solvents and surfactant methods. The miscible solvent method can be further divided into monocomponent and polycomponent methods. This paper compares the advantages and disadvantages of the existing techniques for measuring and reducing MMP and selects the best method.

The economic feasibility of CO 2 -enhanced oil recovery (EOR) to offset CO 2 capture costs from a coal-fired power plant are evaluated for thirty-six source-sink scenarios in Ohio; one of the top ten states for fossil fuel use and CO 2 emissions in the United States. Six capture scenarios are examined for a representative 550-megawatt (MW) coal-fired power plant, and three CO 2 -EOR injection scenarios are evaluated for both the East Canton oil field (ECOF) and Gore Consolidated oil field (GCOF). The potential costs and credits associated with CO 2 storage-related tax incentives are also considered. Power plant capture performance and costs integrated with field-scale CO 2 -EOR technoeconomics suggest there are potentially feasible scenarios for capture, transport, and CO 2 -EORstorage of 25%, 50%, and 90% of CO 2 emissions from a 550 MW power plant. Economically feasible outcomes exhibiting net present values (NPV) of $2,191, $1,380, and $1,940 million are estimated for the 25%, 50%, and 90%, capture scenarios, respectively. On average, the 45Q tax credit for CO 2 storage affords a $3 to $7 per barrel decrease in the minimum oil price required to break-even on the project. In all source-sink scenarios qualifying as feasible, the CO 2 capture costs incurred by the power plant are offset by revenue from CO 2 -EOR and are not passed on to ratepayers during the thirty-year analysis time frame. The most economical outcome for supporting a commercial carbon, capture, utilization and storage (CCUS) project in Ohio is also identified, and the potential impact of CO 2 -EOR operational strategy on source-sink feasibility is discussed.

“…The reported equation was correlated using three pseudo-components presenting a multi-components system, and some satisfactory results were obtained based on this model. Thereafter, an increasingly number of correlations were developed for MMP prediction [ 17 , 18 , 19 , 20 ]. Researchers found that the more useful parameters an equation used, the better performance the model had [ 21 ].…”

CO2 enhanced oil recovery (CO2-EOR) has become significantly crucial to the petroleum industry, in particular, CO2 miscible flooding can greatly improve the efficiency of EOR. Minimum miscibility pressure (MMP) is a vital factor affecting CO2 flooding, which determines the yield and economic benefit of oil recovery. Therefore, it is important to predict this property for a successful field development plan. In this study, a novel model based on molecular dynamics to determine MMP was developed. The model characterized a miscible state by calculating the ratio of CO2 and crude oil atoms that pass through the initial interface. The whole process was not affected by other external objective factors. We compared our model with several famous empirical correlations, and obtained satisfactory results—the relative errors were 8.53% and 13.71% for the two equations derived from our model. Furthermore, we found the MMPs predicted by different reference materials (i.e., CO2/crude oil) were approximately linear (R2 = 0.955). We also confirmed the linear relationship between MMP and reservoir temperature (TR). The correlation coefficient was about 0.15 MPa/K in the present study.
