Summary: CO2 injection has a significant influence on the poroviscoelastic response of reservoir rock, particularly in terms of poroelastic and hydraulic properties. The treatment of CO2 increases the compressibility of the rock and induces chemical effects such as dissolution and stress corrosion cracking. Additionally, CO2 treatment facilitates viscous response and leads to increased permeability. Properly characterizing the time-dependent behavior is crucial for geologic storage projects.

Summary: Many studies have been conducted to evaluate the long-term integrity of seals in CO2 storage sites, focusing on the geochemical reactions, mineral transformations, and surface wettability alterations that may occur. This study specifically examined changes in mineralogy and surface wettability of shales exposed to supercritical CO2 for 6 months, finding that quartz dissolution and kaolinite precipitation can be induced in the presence of CO2. The study suggests that maintaining water wettability of clay surfaces in storage sites is important to prevent CO2 migration. Further research is needed to ensure the integrity of seals in storage sites during and after injection.

Summary: Surface wettability plays a crucial role in controlling CO2 seal capacity and storage potential of shales. Strong correlation between mineral composition and alteration in shale/water wettability was observed, with clay-rich shales showing a possible transition to CO2-wet behavior. Increasing temperature accelerates CO2/shale interactions, while higher cohesive energy density of CO2 promotes a favorable CO2 wetting environment. Shales with high quartz contents exhibit strong water wetting behavior after SCCO2 treatment, enhancing their sealing capacity and potential for CO2 containment in geological storage sites.

Summary: Mine tailings are waste products that need to be managed due to their high erosion potential and unwanted mineral content. Assessing long-term erosion behavior of tailings dams is important and can be improved using Landscape Evolution Models. Different designs of tailings dams can have varying erosion rates, with potential for long-term encapsulation of tailings if properly maintained.

Summary: The study utilized field data for numerical modeling of long-term CO2 storage and revealed that the dominant storage mechanism during CO2 injection was structural trapping, while residual gas trapping occurred after injection cessation. Significant changes in storage mechanisms occurred within 20 years post-injection, transitioning to solubility trapping after 100 years with decreased residual CO2 trapping. Mass diffusion of CO2 controlled CO2 invasion into the cap rock over a simulation period of 1000 years.

Summary: This paper proposes a nested model for the multi-objective optimal dispatching of reservoirs, which solves the problem of coordinating the contradiction between long-term and short-term benefits in the existing models. The results show that the optimal dispatching plan of the nested model has higher benefits while meeting the flood control objectives. In the case of predicting runoff errors, the output control mode is identified as the optimal control mode.

Summary: This study calculated the mass balance of annual and seasonal NO3-N concentration and load reductions for Lake Red Rock, a flood-control reservoir in Iowa. It was found that the reservoir removed an average of 7,379 Mg of NO3-N per year, accounting for 12.4% of the inputs. The annual NO3-N reduction in flood-control reservoirs in the Midwest is logarithmically related to the average annual water retention time.

Summary: The adsorption behavior of water vapor in silica nanopores with different pore morphologies and surface hydrophilicities was studied. The study found that the adsorption isotherms are largely independent of pore size at low pressure, and the adsorbed amounts scale with the surface hydroxyl density. Patchy adsorbed layers were found in narrow pores, while a second adsorbed water layer was formed on larger pores and planar quartz surfaces. Molecular dynamics modeling revealed two preferential orientations for water molecules adsorbing to surface hydroxyl groups.

Summary: In this study, small-angle neutron scattering experiments were conducted on 71 samples from 13 different sets of mudrocks across the globe to capture the pore structure and develop fractal models to predict transport properties based on pore size distributions. The results show that transport phenomena in mudrocks are pore size-dependent, with different flow regimes developing in micropores, meso- and macropores based on hydrostatic pore pressures. The new model of pore size-dependent transport and integrated transport properties using fractal models provides a systematic approach to better understand fluid flow and transport phenomena in mudrocks on the reservoir and basin scale.

Summary: The long-term interaction of CO2-charged fluids with low permeability cap rocks is important for seal integrity assessment. A study on a natural CO2 analogue near Green River, Utah, USA, showed that over time and small distances, mechanical weakening of the cap rock due to fluid-rock interactions can occur, leading to loss of cohesion, compaction, and formation of fractures. However, considering the thickness of cap rocks above CO2 storage reservoirs, the risk of losing containment integrity over hundreds to thousands of years is not significant.

Summary: This study presents a scalable and energy-efficient hollow fiber membrane contactor (HFMC)-based process for CO2 capture using a green solvent. The use of deep eutectic solvent (DES) in HFMC allows for effective interaction between DES and CO2, overcoming drawbacks of direct absorption in DES. The research evaluates the performance of commercial low-cost polymer hollow fiber membranes in CO2 capture with DES and provides insights into the CO2 separation mechanism.

Summary: The pore structure of mudrocks plays a vital role in evaluating flow behavior, and the relationship between porosity evolution and flow and transport in mudrocks remains insufficiently understood. Organic-rich mudrocks mainly contain large pores, which favor production from unconventional reservoirs. The research findings are of great significance for understanding fluid imbibition and flow properties in mudrocks.

Summary: Oil and gas wells can experience integrity failure, leading to the release of fugitive gas into the subsurface and atmosphere. This study focuses on understanding the factors influencing fugitive gas migration in the shallow sedimentary rocks of British Columbia, Canada, and developing methods to detect and monitor these gases. Laboratory techniques and analytical calculations were used to characterize flow properties of rock cores and assess the relationship between petrophysical characteristics and flow propensity. Results indicate that capillary pressure and heterogeneity play significant roles in controlling gas migration in the region.

Summary: This study investigates the long-term geomechanical changes in a reservoir seal due to fluid-rock interactions with CO2-charged fluids. The study finds that low permeability cap rock undergoes mechanical weakening over time, resulting in the formation of bedding-parallel fractures. However, these mechanical weakening processes only occur over long time scales and small distances, suggesting that the threat to containment integrity is not considerable.
