“…The oil industry also takes the advantage of CO 2 injection into oil and gas reservoirs as a promising enhanced oil recovery (EOR) method 7 , 8 . Moreover, the combination of water and CO 2 injection, which is known as water-alternating-gas (WAG), is considered a successful technique because of its ability to control gas mobility and reduce the viscous fingering phenomenon 9 , 10 . As seen in many fields, the interactions between water and CO 2 play an important role and the dissolution of CO 2 could affect the ultimate storage capacity in CCS 11 , 12 and the performance of EOR methods.…”

The growing application of carbon dioxide (CO2) in various environmental and energy fields, including carbon capture and storage (CCS) and several CO2-based enhanced oil recovery (EOR) techniques, highlights the importance of studying the phase equilibria of this gas with water. Therefore, accurate prediction of CO2 solubility in water becomes an important thermodynamic property. This study focused on developing two powerful intelligent models, namely gradient boosting (GBoost) and light gradient boosting machine (LightGBM) that predict CO2 solubility in water with high accuracy. The results revealed the outperformance of the GBoost model with root mean square error (RMSE) and determination coefficient (R2) of 0.137 mol/kg and 0.9976, respectively. The trend analysis demonstrated that the developed models were highly capable of detecting the physical trend of CO2 solubility in water across various pressure and temperature ranges. Moreover, the Leverage technique was employed to identify suspected data points as well as the applicability domain of the proposed models. The results showed that less than 5% of the data points were detected as outliers representing the large applicability domain of intelligent models. The outcome of this research provided insight into the potential of intelligent models in predicting solubility of CO2 in pure water.

Despite rapid advances in renewable energy extraction and utilization, global oil demand continues to rise. Oil displacement technologies are widely studied and applied because they can extract more oil in depleted reservoirs or recover unconventional ones. This study introduces research methods and mechanisms of four oil displacement technologies, i.e., water flooding, chemical flooding, gas flooding, and steam flooding. Although oil displacement technologies are helping to meet the growing demand for oil and energy, there are still some challenges for industrial applications. Some agents adopted in the oil displacement have shortcomings in the corrosion of mining equipment and damage to the reservoir structure. Therefore, solutions to the problem are crucial and are investigated widely in the literature using experiments and simulations. For experimental research, a diffusion framework for studying mass transfer in the oil displacement process and an experimental system for simulating oil displacement in offshore reservoirs should be built, which will facilitate the widespread industrial application of oil displacement technology. Therefore, it is necessary to improve the accuracy and expand the application range of the experimental system. As for numerical simulation, reaction kinetics research is essential for selecting displacement agent materials and preventing harmful gas leakage for industrial applications. However, the dynamics of foam flooding and CO2 flooding are not thoroughly studied. Moreover, it is an acceptable research topic that reducing the uncertainty of discrete regions is an effective method to improve the accuracy of numerical simulation results. For the broader application of oil displacement technology to industry, several mechanisms regarding the research field could be studied more thoroughly and comprehensively in the future, i.e., (1) the influence mechanisms of some impurities and complex reservoir physical properties, (2) the method of combining various oil displacement technologies, (3) the T-H-M-C multifield coupling oil displacement mechanism at micro/nanoscale, (4) the cement failure mechanism caused by CO2 and H2S, and (5) the tube brittle fracture mechanism caused by stress corrosion. For the sustainable development and efficient utilization of oil displacement, this review summarizes the extensive information about four oil displacement technologies, thus encouraging and providing research topics for further development and applications.

“…Chemical agents and additives may be used to get rid of a particular complicating factor or several factors simultaneously (combined-effect chemicals). The critical factor contributing to treatment success and efficiency is the choice of chemical [21,22]. The works [23][24][25][26][27][28] selected a demulsifier grade and determined consumption to inhibit emulsification during water-in-oil emulsion production and transportation, which showed a high degree of breakdown at the in-pipe demulsification stage and during oil treatment.…”

A new integrated oil production enhancement technology based on water-flooding energy recovery is proposed. After providing an extensive review of the existing scientific and technical literature on this subject, the proposed integrated technology is described together with the related process flow diagram, the criteria used to select a target facility for its implementation and the outcomes of the laboratory studies conducted to analyze emulsion formation and separation kinetics. Moreover, the outcomes of numerical simulations performed using Ansys CFX software are also presented. According to these results, using the proposed approach the incremental oil production may reach 1.2 t/day (with a 13% increase) and more, even at low flow rates (less than 10 t/day), thereby providing evidence for the benefits associated with this integrated technology.
