“…The microbial activity in soil column R decreased significantly after high-temperature treatment, while the Phreeqc simulation process could not consider the change in microbial activity. Moreover, the CO 2 concentration in soil column R was obviously higher, and the mineral solubility was obviously increased (Ding et al 2018), which led to the difference in the water-rock reaction (Kim et al 2019), causing soil column R to show results similar to the simulation results. In other words, CO 2 has an effect on the chemical composition of water under the same environmental conditions.…”

The water quality of the rainwater is obviously different from that of the groundwater after it reaches the surface and passes through the vadose zone. This study aims to further evaluate and analyze how soil CO 2 changes under natural conditions, to provide a theoretical background for the establishment of CO 2 geological storage, and to provide a basis for the detection of CO 2 leakage in order to provide insights for expanding CO 2 research. The changes in soil CO 2 concentration under different conditions were simulated and analyzed by laboratory experiments, and the effects of CO 2 on water chemical composition were also analyzed. In this study, two experimental groups (vegetation group (V) and high-temperature sterilization group (R)) and one blank group (B) were established. The results showed that the CO 2 concentration in column R was the lowest, while that in column V was the highest. With rainfall infiltration, soil CO 2 concentration gradually increased. When the rainwater infiltrated to 215 cm, the CO 2 concentrations in the columns V, B, and R were 5100 mg•m −3 , 4450 mg•m −3 , and 32,000 mg•m −3 , respectively. At infiltration depths from 5 to 215 cm, the Na + , Ca 2+ , Mg 2+ , SO 4 2− , and HCO 3 − concentrations in columns V and B decreased, whereas they increased in soil column R. The simulation revealed that the CO 2 concentration ranged from 560 mg•m −3 to 50,000 mg•m −3 ; pH value decreased; NO 3 − and Cl − remained stable; SO 4 2− decreased; and fCO 2 , HCO 3 − , Ca 2+ and Mg 2+ increased.

Flue gas flooding is one of the important technologies to improve oil recovery and achieve greenhouse gas storage. In order to study multicomponent flue gas storage capacity and enhanced oil recovery (EOR) performance of flue gas water-alternating gas (flue gas–WAG) injection after continuous waterflooding in an oil reservoir, a long core flooding system was built. The experimental results showed that the oil recovery factor of flue gas–WAG flooding was increased by 21.25% after continuous waterflooding and flue gas–WAG flooding could further enhance oil recovery and reduce water cut significantly. A novel material balance model based on storage mechanism was developed to estimate the multicomponent flue gas storage capacity and storage capacity of each component of flue gas in reservoir oil, water and as free gas in the post-waterflooding reservoir. The ultimate storage ratio of flue gas is 16% in the flue gas–WAG flooding process. The calculation results of flue gas storage capacity showed that the injection gas storage capacity mainly consists of N2 and CO2, only N2 exists as free gas phase in cores, and other components of injection gas are dissolved in oil and water. Finally, injection strategies from three perspectives for flue gas storage, EOR, and combination of flue gas storage and EOR were proposed, respectively.

“…Similarly, Suekane et al (2008) determined the residual and solubility capacities available in Japanese aquifers. By improving on the flaws of the conventional analytical techniques for storage estimation, Ding et al (2018) proposed new analytical methodologies for the determination of solubility and mineral trapping in aquifers and depleted oil reservoirs. Their model was applied to the HB oil field in China, and estimates were compared to a similar methodology by Xu et al (2004) with slight discrepancies observed.…”

The merits of CO 2 capture and storage to the environmental stability of our world should not be underestimated as emissions of greenhouse gases cause serious problems. It represents the only technology that might rid our atmosphere of the main anthropogenic gas while allowing for the continuous use of the fossil fuels which still power today's world. Underground storage of CO 2 involves the injection of CO 2 into suitable geological formations and the monitoring of the injected plume over time, to ensure containment. Over the last two or three decades, attention has been paid to technology developments of carbon capture and sequestration. Therefore, it is high time to look at the research done so far. In this regard, a high-level review article is required to provide an overview of the status of carbon capture and sequestration research. This article presents a review of CO 2 storage technologies which includes a background of essential concepts in storage, the physical processes involved, modeling procedures and simulators used, capacity estimation, measuring monitoring and verification techniques, risks and challenges involved and field-/pilot-scale projects. It is expected that the present review paper will help the researchers to gain a quick knowledge of CO 2 sequestration for future research in this field.
