Summary: The dispersion coefficient is a crucial parameter for EGR, influenced by factors such as temperature and flow rate. Research indicates that in high-permeability porous media, the dispersion coefficient of CO2-CH4 is smaller, and the impact of residual water on CO2 dispersion is controversial. Field-scale simulations have verified the feasibility and economic viability of EGR technology.

Summary: This study measured the adsorption of pure and binary CO2 and CH4 in shale using the volumetric method. The results showed that CO2 was preferentially adsorbed in shale, and the adsorption amount of binary CO2/CH4 increased with the increase of CO2 composition. The selectivity factor of CO2 over CH4 was closely related to pressure and CO2/CH4 concentration, and the injection strategy of CO2 can be optimized based on the results.

Summary: The benefits of injecting CO2 into a gas-condensate reservoir include reducing emissions and increasing hydrocarbon production. Investing in low risk projects on already producing natural gas fields is feasible. In late production periods, the process can be carbon-negative, making the enhanced gas recovery scheme advantageous as a preliminary step before converting the reservoir to a CO2 storage facility.

Summary: The study investigated the efficiency of different injection strategies for simultaneous CO2 EOR and storage in ultra-low permeability core samples. Water alternative gas injection was found to be more effective than continuous gas injection, while cyclic gas injection provided the most efficient strategy for enhanced oil recovery in the tight rocks studied.

Summary: The experimental study investigated the competitive adsorption characteristics of CO2-CH4 in tight sandstone, showing that CO2 has a higher adsorption capacity and can displace CH4 in tight cores. The sensitivity experiments demonstrated that competitive adsorption is more significant in tight cores with lower permeability, higher rock fragment content, and lower water saturation. Additionally, for water saturated cores, the dissolution of CO2 in water has a greater impact on EGR and CO2 storage efficiency.

Summary: Shale gas is an important unconventional fossil fuel resource. Carbon capture and sequestration in shale gas reservoirs, known as CO2-EGR, can sequester 45%-60% of injected CO2 in the shale reservoir while providing 10%-15% incremental gas recovery. Factors such as formation temperature, mean pore size, and injection rate greatly impact the feasibility of CO2-EGR.

Summary: Carbonate gas reservoirs in the Sichuan Basin have complex characteristics and injecting CO2 into depleted reservoirs can help achieve carbon neutrality and enhance natural gas recovery. Injecting CO2 into low permeability reservoirs for oil displacement has become an important means to enhance oil recovery. However, the mechanism and field application technology of injecting CO2 into carbonate sour gas reservoirs are still in the exploration stage.

Summary: The study investigates the feasibility of storing CO2 inside hydrate stability zone (HSZ) through reservoir pressure management via water producers and CO2 injectors. Results show that by controlling reservoir pressure, CO2 can be stored in HSZ with the formation of CO2 hydrate delaying CO2 breakthrough and limiting gas leakage. The research highlights the potential of storing CO2 in aquifers with a HSZ, with implications for CO2 geological storage.

Summary: This work investigates the performance of injecting different gases to enhance shale gas recovery and CO2 geological storage efficiency using fractured shale cores under real reservoir conditions. The adsorption process of shale to different gases follows the extended-Langmuir model, with CO2 showing the highest adsorption capacity, followed by CH4, and N-2 having the smallest adsorption capacity. Core flooding tests show that CO2 has a longer breakthrough time compared to N-2, and the recovery factor for CH4 at the breakthrough time is higher for CO2 injection. The storage efficiency of CO2 also increases with increasing CO2 concentration.

Summary: The adsorption characteristics of CO2 and CH4 are different, with CO2 injection leading to an increase in CH4 recovery over time, but a decrease in the mole fraction of CH4. Adsorbents with larger SCO2/CH4 can prolong the stage of CH4 recovery.

Summary: The potential crosslinking of three types of nitrogen-containing functionalized silica (TAAcONa, guanidine, and triamine) with polyacrylamide (PAM) has been investigated, with only triamine silica able to successfully crosslink with PAM. The thermal stability of the functionalized silica was shown to be high, and the crosslinking mechanism of the new crosslinker was proposed to be similar to that of the PAM/PEI system, with functionalized silica-based gels being more stable and possessing higher strength.

Summary: The effect of temperature and pressure on the adsorption of CO2 and CH4 gases on calcite (104) was studied using classical molecular dynamics. Results showed that CO2 greatly enhances methane desorption at low concentrations and temperatures, but this effect diminishes at high temperatures. CO2 adsorption is well-defined and characterized by strong interaction, while methane adsorption is loose and dynamic. Pressure has limited impact on methane adsorption, especially in the presence of high CO2 concentrations.
