“…Compared with tight core C-1 (crude oil), the pore volume of tight core saturated with fluorocarbon oil is 0.178 cm 3 smaller, while the CO 2 injection volume increases by 0.03 cm 3 , indicating that the CO 2 dissolution and diffusion capacity are slightly stronger in the fluorocarbon oil. Simultaneously, through the comparison of CO 2 storage, the CO 2 storage ratio of tight core C-2 is slightly increased (about 1.61%∼1.82%), which may be due to the stronger dissolution and diffusion in fluorocarbon oil …”

CO 2 underground storage is an important approach to reduce carbon emissions; meanwhile, the combination of CO 2 storage and economic benefits can further promote the long-term development of carbon neutrality. Global tight oil reserves are abundant, but the depletion development of most tight reservoirs is unsatisfactory. Therefore, it is crucial to utilize CO 2 storage combined with enhanced oil recovery (EOR) for tight reservoir development. At present, there are few experimental studies on the CO 2 effective distance and CO 2 -EOR storage of huff-n-puff in tight reservoirs. In this paper, the CO 2 effective distance and the evolution of saturation profiles in tight cores are first investigated, and CO 2 -EOR storage is quantitatively evaluated for CO 2 huff-npuff in tight reservoirs based on CT and nuclear magnetic resonance technology. Meanwhile, the influences of oil composition and permeability on the effective distance and CO 2 -EOR storage are further investigated. The results indicate that the increase of CO 2 effective distance gradually slows down with time, and the decrease of permeability significantly reduces the effective distance. Increasing amount of oil is mainly produced in larger pores, which is more than twice of that in smaller pores. CO 2 -EOR storage experiments quantify that the CO 2 storage ratio for a 0.22 × 10 −3 μm2 core is up to 72.31% under different depressurization conditions (12, 8, and 0.1 MPa). With the decrease in production pressure, oil recovery gradually increases, while the CO 2 storage ratio decreases, indicating that there is a collaborative optimization to maximize the oil production and CO 2 storage ratio. Comparison experiments reveal that the oil composition (replaced by fluorocarbon oil) has little influence on the effective distance and CO 2 -EOR storage, while the influence of permeability is significant. The CO 2 effective distance determines the sweep efficiency, so increasing effective distance is essential to enhance oil recovery and CO 2 storage. This research is of great significance for CO 2 utilization and CO 2 storage in tight reservoirs.

“…However, some of the reported field trials produced mixed results. Another numerical flow simulation study by Syed et al revealed that increased cycles (up to four) and injection over 50% pore volume lead to about 6% trapped CO2 volume [66]. In this context, citing different studies, Du and Nojabaei (2019) presented experimental study results of oil recovery ranging from 8 to 48% for the Bakken and 56% for the Eagle Ford rock samples with CO2 huff-n-puff.…”

In recent years, the oil and gas sector has been moving towards green production methods to achieve net-zero emission goals. Governments and corporations have started large-scale initiatives to deploy advanced technologies to reduce carbon footprints and prevent global warming. Herein, we have explored the emerging techniques and methods used in reducing the effects of gas emissions in the oil and gas industry. The transition process from hydrocarbons to renewable energy resources, including solar thermal applications for EOR, thermal energy extraction from hydrocarbon reservoirs, hydrogen generation strategies, and CO<sub>2</sub> EOR and storage applications, has also been discussed. Literature information and publicly available data have paved the way to provide the theoretical background, the rationale of use, screening and selection criteria, challenges, and workarounds for these novel energy sources. Systems to integrate green methods into oil and gas processes appear in detail, from screening to implementation. Then, the technical information for integrating these resources under multiple conditions that affect the system's efficiency, such as weather, seasonal temperature changes, wind, and solar exposure, have been investigated. Moreover, added benefits of such incorporation strategies, such as improved economics with minimal effects on capital intensiveness or other burdens on the overall economy, have also been addressed. The transition from fossil fuels to renewable and greener energy resources provided the underlying motivation for this study.

“…Injection of carbon dioxide in the sub-surface oilbearing formations not only improves the oil recovery but also reduces the carbon footprint from the planet. In [14,15], the issues of demonstration the simultaneous effect of multiple hydraulic fracture parameters and the CO 2 injection volume for the directional EOR and CO 2 trapping performance are considered. However, due to the high cost and the insufficiently high potential productivity of the wells of the Verey facilities in general, this technology is currently unprofitable and does not yet have experience in using Verey deposits.…”

Survey and novel research data are used in the present study to classify/identify the lithological type of Verey age reservoirs' rocks. It is shown how the use of X-ray tomography can clarify the degree of heterogeneity, porosity and permeability of these rocks. These data are then used to elaborate a model of hydraulic fracturing. The resulting software can take into account the properties of proppant and breakdown fluid, thermal reservoir conditions, oil properties, well design data and even the filtration and elastic-mechanical properties of the rocks. Calculations of hydraulic fracturing crack formation are carried out and the results are compared with the data on hydraulic fracturing crack at standard conditions. Significant differences in crack formation in standard and lithotype models are determined. It is shown that the average width of the crack development for the lithotype model is 2.3 times higher than that for the standard model. Moreover, the coverage of crack development in height for the lithotype model is almost 2 times less than that for the standard model. The estimated fracture half-length for the lithotype model is 13.3% less than that of for the standard model. A higher dimensionless fracture conductivity is also obtained for the lithotype model. It is concluded that the proposed approach can increase the reliability of hydraulic fracturing crack models.
