“…The impact of impure CO 2 on both EOR and carbon capture and storage (CCS) performance has attracted significant research interest. 50 Several studies have been conducted to analyze the effects of impurities such as CH 4 , H 2 , N 2 , O 2 , Ar, H 2 S, natural gas liquids (NGL), and SO 2 on various aspects of the CO 2 -EOR. Nogueira and Mamora (2008) studied the impact of impurities in flue gas injection in depleted reservoirs.…”

To enhance oil production from carbonate reservoirs, the implementation of advanced enhanced oil recovery (EOR) techniques has been proposed. This research evaluates the potential of flue gas and CO 2 in water alternating gas (WAG) injection in a homogeneous fractured carbonate reservoir characterized by low porosity and permeability, incorporating water salinity as a hybrid method. Simulations were conducted using Eclipse (E300) software to assess the effectiveness of this approach. The optimization of the hybrid EOR method, including modified hybrid EOR, simultaneous water and gas (SWAG) incorporating flue gas, CO 2 , and low salinity water, as well as the optimization of injection patterns for flue gas-LSWAG and CO 2 -LSWAG, were analyzed to achieve the optimal oil recovery factor. The simulation results indicated that natural production from the reservoir accounted for only 29% of the total, highlighting the necessity of implementing EOR methods to enhance oil recovery. Three types of flue gases, derived from steel, cement, and power plants, along with CO 2 , were considered in this study. The findings revealed that modification of the hybrid EOR method resulted in the highest oil recovery factor, reaching approximately 85%. Additionally, gas injection using CO 2 exhibited a higher oil recovery factor compared to flue gas injection, which demonstrated the lowest performance. Therefore, the hybrid flue gas-WAG method was recommended due to its significant increase in the recovery factor. Furthermore, the study investigated the impact of water salinity on performance, with CO 2 -HSWAG outperforming CO 2 -LSWAG in terms of recovery factor, indicating a positive response to an increase in water salinity. Conversely, the evaluation of flue gases had a negative effect on oil recovery. The study also observed the positive effectiveness of exceeding gas injection patterns in CO 2 -LSWAG, as well as the sensitivity of flue gas compositions on the oil recovery factor. Thus, this research illustrated the diverse potential of flue gases in hybrid EOR.

Carbon Capture, Utilization, and Storage (CCUS) stands as one of the effective means to reduce carbon emissions and serves as a crucial technical pillar for achieving experimental carbon neutrality. CO2-enhanced oil recovery (CO2-EOR) represents the foremost method for CO2 utilization. CO2-EOR represents a favorable technical means of efficiently developing extra-low-permeability reservoirs. Nevertheless, the process known as the direct injection of CO2 is highly susceptible to gas scrambling, which reduces the exposure time and contact area between CO2 and the extra-low-permeability oil matrix, making it challenging to utilize CO2 molecular diffusion effectively. In this paper, a comprehensive study involving the application of a CO2 nanobubble system in extra-low-permeability reservoirs is presented. A modified nano-SiO2 particle with pro-CO2 properties was designed using the Pickering emulsion template method and employed as a CO2 nanobubble stabilizer. The suitability of the CO2 nanobubbles for use in extra-low-permeability reservoirs was evaluated in terms of their temperature resistance, oil resistance, dimensional stability, interfacial properties, and wetting-reversal properties. The enhanced oil recovery (EOR) effect of the CO2 nanobubble system was evaluated through core experiments. The results indicate that the CO2 nanobubble system can suppress the phenomena of channeling and gravity overlap in the formation. Additionally, the system can alter the wettability, thereby improving interfacial activity. Furthermore, the system can reduce the interfacial tension, thus expanding the wave efficiency of the repellent phase fluids. The system can also improve the ability of CO2 to displace the crude oil or water in the pore space. The CO2 nanobubble system can take advantage of its size and high mass transfer efficiency, among other advantages. Injection of the gas into the extra-low-permeability reservoir can be used to block high-gas-capacity channels. The injected gas is forced to enter the low-permeability layer or matrix, with the results of core simulation experiments indicating a recovery rate of 66.28%. Nanobubble technology, the subject of this paper, has significant practical implications for enhancing the efficiency of CO2-EOR and geologic sequestration, as well as providing an environmentally friendly method as part of larger CCUS-EOR.
