Summary: Understanding crystallization pathways at nanoscale under high pressure and temperature is challenging. This study used high-pressure atomic force microscopy to directly observe brucite carbonation in water-bearing supercritical carbon dioxide, revealing that the amorphous magnesium carbonate acts as a seed for the crystallization of nesquehonite. Additionally, in situ infrared and thermogravimetric-mass spectrometry analyses indicated the stoichiometry of the amorphous intermediate.

Summary: Understanding the mass transfer of CO2 into formation brine is crucial for the safety of geologic carbon sequestration. This study used quasi-dynamic X-ray micro-computed tomographic imaging to track the evolution of scCO2 clusters in sandstone during brine injection. The mass transfer coefficient of individual scCO2 clusters was found to range between 3.0x10-5 and 3.5x10-4 mm/s, with a macroscopic average of 1.4x10-4 mm/s. These values provide insight into the range of mass transfer coefficients expected for similar conditions. The study also highlighted the coupling of dissolution and mobilization processes, emphasizing the need to understand these dynamics for effective CO2 storage.

Summary: The functioning of natural and engineered porous media relies on the interplay between biochemical processes and hydrodynamics. In such environments, biofilms often form, altering the distribution of fluid flow velocities and affecting their permeability. However, the control of biofilm clustering and resulting permeability heterogeneity is not well understood, limiting predictive abilities for biofilm-porous medium systems.

Summary: This study examined the changes in the effective stress coefficient for permeability (chi) of dry and wet shale samples with different times of supercritical CO2 exposure. The presence of water intensifies the response of shale to ScCO2, resulting in greater increase in chi for wet shale compared to dry shale.

Summary: This study investigates the impact of ScCO2-water exposure on shale properties and reveals the changes in mineral composition, pore structure, and mechanical properties due to the chemical-mechanical interaction. The results indicate that the interaction leads to changes in shale porosity and permeability, with chemical reactions increasing the porosity in unstressed conditions and the chemical-mechanical coupling effects decreasing the permeability in stressed conditions. The findings highlight the importance of understanding the chemical-mechanical processes in shale for optimizing gas recovery and CO2 sequestration.

Summary: Understanding the mechanism of biofilm distribution and detachment is crucial for water treatment and prevention of clogging in porous media. This study reveals that bacterial aggregation in smaller pores leads to biofilm formation and blockage. The detachment of biofilm is correlated with its morphology and permeability, and occurs through internal detachment or external erosion.

Summary: Permeability rebound and recovery during the permeability evolution process is an important behavior affected by temperature and reservoir pressure changes. A binary gas permeability evolution model was used to study the dynamic evolution of various parameters during CO2 injection into CH4-containing coal at different temperatures. The study found that permeability shows a complex evolution over time, with the time required for rebound and recovery increasing with temperature. Monitoring gas migration patterns revealed that CO2 flow rate and cumulative storage volume decrease with increased rebound and recovery time. The study proposed using the stage-pressure injection method to increase CO2 injection effect.

Summary: An autoclave was used to study the effect of mineral changes on coal pore structure in the presence of water. The pore complexity was analyzed using various experimental techniques, such as mercury intrusion capillary pressure, low-pressure nitrogen adsorption, CO2 adsorption, and field emission scanning electron microscopy. The results showed that the pore morphologies were controlled by the dissolution of carbonate particles, and the newly generated micropores had more uniform and regular shapes.

Summary: CO2 storage in shale formation is a potential means to reduce CO2 emissions and achieve carbon neutrality. The interaction between CO2 and shale leads to changes in permeability, which is crucial for CO2 sequestration. This study investigated the effect of supercritical CO2 exposure time on the porosity and permeability evolution of dry and wet shale samples. The results showed that the porosity and permeability of both dry and wet shale initially increased and then decreased with exposure time, with an inflection point. The evolution of porosity and permeability in shale is controlled by the chemical-mechanical coupling effects, with mineral dissolution and mechanical weakening playing key roles. The inflection time was earlier in wet shale, indicating a shorter period of chemical dominance compared to dry shale. These findings highlight the importance of considering time-dependent chemical-mechanical coupling effects when evaluating shale gas production and CO2 storage capacity.

Summary: This paper conducted experimental studies on the percolation, permeability, and adsorption of supercritical CO2 in coal seams, and analyzed the effects of injection pressure and temperature. The results showed that the permeability of supercritical CO2 in coal increased by 93% compared to CO2. The excess adsorption capacity of supercritical CO2 by coal decreased with increased pressure, and the adsorption capacity decreased by 8.3% on average with a temperature increase of 10 degrees C. The propagation velocity of the longitudinal wave in the sample decreased significantly after the action of supercritical CO2, indicating its effective promotion of pore and fracture development in coal.

Summary: The application of liquid CO2-slickwater hybrid fracturing technology can improve the energy-enhancing efficiency and fracturing fluid flowback efficiency of shale reservoirs. However, the retention of supercritical CO2 (ScCO2) fluid and slickwater in reservoirs after fracturing limits the understanding of changes in shale pore structure, which affects the evaluation of gas adsorption, transportation behaviors, and CO2 sequestration capacity in shale reservoirs. Therefore, the influences of ScCO2-slickwater coupling effect on shale pore structure were analyzed using various analytical methods.

Summary: This study investigated the use of calcium carbonate biomineralization techniques to improve the compressive strength of plastic-reinforced mortar (PRM) made from low-value plastic waste. The microbial-induced calcium carbonate precipitation (MICP) treatment showed promise in significantly enhancing the strength of PRM, making it comparable to plastic-free mortar. This suggests that MICP-treated PRM has potential as a method to effectively reuse plastic waste.
