“…However, in certain reservoirs, the high miscibility pressure presents a challenge for achieving miscibility under reservoir pressure conditions. Some additives, as shown in [31,32], effectively reduce the miscibility pressure by decreasing the interfacial tension (IFT) between oil and CO 2 , thus enhancing the miscible displacement of oil by CO 2 [33]. In this study, it was found that the miscible displacement effect was achieved in the studied oil reservoir without the use of any additives mentioned earlier.…”

This paper addresses the problem of hydrogen generation from hydrocarbon gases using Steam Methane Reforming (SMR) with byproduct CO2 injected into and stored in a partially depleted oil reservoir. It focuses on the reservoir aspects of the problem using numerical simulation of the processes. To this aim, a numerical model of a real oil reservoir was constructed and calibrated based on its 30-year production history. An algorithm was developed to quantify the CO2 amount from the SMR process as well as from the produced fluids, and optionally, from external sources. Multiple simulation forecasts were performed for oil and gas production from the reservoir, hydrogen generation, and concomitant injection of the byproduct CO2 back to the same reservoir. EOR from miscible oil displacement was found to occur in the reservoir. Various scenarios of the forecasts confirmed the effectiveness of the adopted strategy for the same source of hydrocarbons and CO2 sink. Detailed simulation results are discussed, and both the advantages and drawbacks of the proposed approach for blue hydrogen generation are concluded. In particular, the question of reservoir fluid balance was emphasized, and its consequences were presented. The presented technology, using CO2 from hydrogen production and other sources to increase oil production, also has a significant impact on the protection of the natural environment via the elimination of CO2 emission to the atmosphere with concomitant production of H2.

“…Tetrahedrons A-BCD covered the water sample points to a maximum of 72. (1) Maximum coverage tetrahedron method As shown in Figure 14, a tetrahedron is established with reference water sample points A, B, C, and D as endpoints, and the four sample points A, B, C, and D are in the order of I water sources (15), II water sources (40), III water sources (24), and IV water sources (21). By using the loop algorithm to traverse 300,000 combinations, it is determined that tetrahedrons established at four water sample points A, B, C, and D could cover the sample points to the maximum extent.…”

After a mine water inrush occurs, it is crucial to quickly identify the source of the water inrush and the key control area, and to formulate accurately efficient water control measures. According to the differences in water chemical characteristics of four aquifers in the Fenyuan coal mine, the concentrations of K+~Na+, Ca2+, Mg2+, Cl−, SO42−, and HCO3− were taken as water source identification indexes. A decision tree classification model based on the C4.5 algorithm was adopted to visualize the chemical characteristics of a single water source and extract rules, and intuitively obtained the discrimination conditions of a single water source with Mg2+, Ca2+, and Cl− as important variables in the decision tree: Mg2+ < 39.585 mg/L, Cl− < 516.338 mg/L and Mg2+ ≥ 39.585 mg/L, Ca2+ < 160.860 mg/L. Factor analysis and Fisher discriminant theory were used to eliminate the redundant ion variables, and the discriminant function equations of the two, three, and four types of mixed water sources were obtained successively in turn. This paper puts forward MSE, RMSE, and MAE as the evaluation indexes of the water source mixing degree calculation models and obtains the ranking of the pros and cons of the mixed water source mixing degree calculation models. The results show that the minimum inscribed circle analytical method is the optimal model for the calculation of the mixing degree of two types of water sources, and the MSE, RMSE, and MAE are 0.17%, 4.13%, and 4.13%, respectively. The minimum inscribed circle clustering method is the optimal model for the calculation of the mixing degree of three types of water sources, and the minimum distance method is the optimal model for the calculation of the mixing degree of four types of water sources. The method of mine water source identification based on the decision tree C4.5 algorithm and mixing degree calculation has the characteristics of a simple calculation process, high efficiency, objective accuracy, and low cost, which can provide a scientific basis for the development of stope water control measures.

Recently, smart water (SmW) and nanocomposite (NC) flooding have shown good potential for enhanced oil recovery (EOR) processes. Although SmW and NCs are found to influence the oil recovery, there are still some controversies regarding their performance on wettability alteration (WA). To address this important question, we synthesized new NC materials with high hydrophilic properties. In this research, in the first stage, a NC was synthesized. The obtained compound was known as (UiO-66-NH2/TiO2/ZnO) (UNTZ). For the identification of NC, scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET), Fourier transform infrared spectroscopy (FTIR), and X-ray Diffraction (XRD) techniques were used. Furthermore, zeta-potential analysis was done to investigate the stability of nanofluids (NFs). To investigate the effect of NFs on oil recovery, 8 concentrations (1600, 1400, 1200, 900, 700, 500, 300, and 100 ppm) of UNTZ nanofluids were prepared. In the current work, to investigate the effectiveness of the combination of SmW (sulfate (SO42−) and calcium (Ca2+)) + NCs, tests such as interfacial tension (IFT), contact angle, and coreflooding were used. The results of contact angle tests showed improved SmWs capabilities in the presence of NCs that a very effective reduction was accessible and highly hydrophilic wettability was obtained when using SmWs with stable NC as a minimum contact angle of 28° was achieved. The findings of the coreflood experiment indicated that at SmW(SmW2sulfate) + 100 ppm NC and SmW(SmW2calcium) + 100 ppm NC concentrations, the NF enhanced the oil recovery by 9.8 and 5.9%, respectively. This research offers new findings that can help oil recovery by understanding smart water technology with nanoparticle (NPs) in reservoirs (carbonate).
