Carbon Capture, Utilization, and Storage (CCUS) technology has emerged as the bottom-line technology for achieving carbon neutrality goals in China. The development of Carbon Dioxide Enhanced Oil Recovery (CO2-EOR) not only increases revenue for high-investment CCUS projects but also enables permanent CO2 storage in the oil reservoir. However, the basin is used as the research object to evaluate the CO2 storage potential of the oil reservoir. The evaluation results are inaccurate and unable to support the implementation of later CCUS projects. Here, more accurate oil reservoir data is employed as the evaluation object. It is the first time at the national level to screen oil reservoirs to distinguish between CO2 miscible and immiscible, and evaluate the potential of CO2-EOR and CO2 storage in the reservoir. The research results show a total of 2570 suitable oil reservoirs in 4386 candidate oil reservoirs nationwide. About 1.26 billion tons of additional crude oil can be produced by CO2-EOR technology. This includes approximately 580 million tons of additional oil from CO2 miscible flooding and 680 million tons from CO2 immiscible flooding. The study further refines the CO2 geological utilization data and provides a theoretical basis for CCUS project site selection in China.

“…The screening evaluation of reservoirs is the first step in a CO2 flooding project to improve oil and gas recovery, and the results of the screening evaluation can predict to some extent whether the project can be successfully implemented [5][6]. With the application of gas injection development technology in oil and gas reservoirs, some experts and scholars have proposed different screening criteria and evaluation methods.…”

CO2 injection to the middle and late stage of development of condensate gas reservoir can not only improve gas well recovery, but also realize the stable storage of CO2, which is of great practical significance to our energy development strategy, and conducive to the realization of "peak carbon neutralization". Comprehensive evaluation of CO2 injection suitability before CO2 injection in condensate gas reservoirs is an important basis for successful CO2 flooding in the field. Firstly, a comprehensive evaluation method of CO2 flooding suitability for condensate gas reservoirs is established based on fuzzy mathematics; secondly, on the basis of literature research, existing indoor experiments and field experience, the influencing factors of CO2 injection in condensate gas reservoirs are summarized, and new evaluation criteria of CO2 injection suitability (4 primary indicators and 14 secondary indicators) are established and quantified; finally, the weights of 4 primary indexes and 14 secondary indexes are determined by AHP(analytic hierarchy process). Based on the above evaluation method, three blocks of HC gas reservoir were evaluated for the suitability of CO2 injection, and the practicality and reliability of this evaluation method were verified by comparing the evaluation results with the ultimate recovery of condensate gas reservoir in each block. This provides a new idea for the scheme adjustment of further development in the middle and later stages of condensate gas reservoir development.

Numerous studies have investigated the fundamental mechanisms by which CO2 flooding can increase oil production by altering the properties of the hydrocarbon fluid, including oil swelling, viscosity and interfacial tension reductions, and the extraction of light-to-intermediate components. However, the interactions between CO2 and hydrocarbon fluid may also cause several problems, such as asphaltene precipitation due to crude oil's instability during the CO2 flooding process. This study investigates the complex factors that affect the instability of crude oil, including CO2 injection pressures, temperatures, and crude oil compositions. The light-dead oil samples taken from two Indonesian oil fields were used. The impacts of the instability of crude oil on CO2 displacement performance were also observed to evaluate oil recovery and minimum miscibility pressure (MMP). The observation was performed using a slim tube under varying CO2 high-pressure injections at 90 °C and 70 °C. The produced oils were analyzed based on their polarity component, saturates, aromatics, resins, and asphaltenes fractions, to observe the changes in oil composition and colloidal index instability. The results showed that increasing temperatures at given pressures resulted in higher oil recovery. Moreover, the asphaltene and resin fractions in the oil produced at a lower temperature significantly decrease compared to those at a higher temperature. It was also shown that asphaltene tends to precipitate more easily at a lower temperature. The other phenomenon revealed that the lighter oil resulted in a lower recovery than the heavier oil at a given pressure and temperature and correspondingly higher MMP. It was also suggested that CO2 flooding is more likely to cause asphaltene precipitation in light oils.
