Summary: CO2 marine geological sequestration is a crucial measure to reduce atmospheric CO2 levels and mitigate the harmful effects of global warming. Compared with traditional terrestrial geological sequestration, CO2 marine geological sequestration has greater potential, a safer distance from aquifers, and stable temperature and pressure conditions, making it safer and more efficient. This paper reviews and evaluates the main CO2 marine geological sequestration technologies and discusses their mechanisms, potential, challenges, and adverse effects on marine environments. The potential development trends in CO2 marine geological technology are also explored.

Summary: Carbon capture and sequestration (CCS) is the only viable method for reducing massive amounts of carbon dioxide (CO2) from the atmosphere. However, the process poses geomechanical risks, such as caprock failure and induced seismicity, which may lead to environmental concerns and hinder public acceptance. This paper provides an overview of these risks, reviews their mechanisms and theories, and introduces relevant precedent studies. The study aims to enhance understanding of geomechanical risks during CCS and facilitate the optimal design of the process for public acceptance. Challenges related to handling these risks are also discussed.

Summary: This paper explores the adsorption behaviour of geomaterials in the CO2 sequestration process in shallow level coal seams. The experiments reveal that moisture, volume expulsion behaviour, and coal-water interaction influence the adsorption capacity of coal samples. Wet conditions and biofilm affect the adsorption capacity of sand and its chemisorption capacity. Furthermore, bentonite shows a greater affinity towards CO2. The findings provide insights into the effect of biogeological conditions on CO2 storage in coal seams.

Summary: This study applies the sequence-stratigraphic method to assess the containment potential and risk of geological carbon sequestration. The findings suggest that clay-mineral aggregates provide the most consistent excellent seals, while more distal rock facies have lower containment capacity. The geometry and extent of favorable top seals are influenced by the basin type and sediment delivery.

Summary: This study examines the impact of geological heterogeneity on CO2 capillary trapping using numerical simulations, finding that the amount of trapped CO2 can vary significantly depending on geological scenarios and petrophysical uncertainties. Upscaling from core-scale experimental data using the Land trapping parameter may enhance heterogeneity trapping, while including capillary pressure hysteresis in the numerical model could reduce it by up to 70%.

Summary: Geological CO2 sequestration (GCS) is the main solution to mitigate global warming. This study aims to investigate the temperature effect on CO2 transport and dissolution in a field case. A numerical model is developed to simulate the reactive thermohaline convection (RTHC) processes. Results show that including the temperature effect intensifies fingering processes and CO2 dissolution, and neglecting it can significantly impact model predictions.

Summary: In this study, the mechanisms of frost cracking as a result of freeze-thaw cycling, confining stress, and the interaction of multiple cracks were investigated using experimental, theoretical, and numerical approaches. The experimental and numerical results showed that frost cracks tend to propagate in the direction of maximum principal stress, and the position and orientation of initial cracks significantly influence the interaction effect between two frost cracks.

Summary: This study analyses the flow of brine in rock salt using a fully coupled THM model that considers non-isothermal two-phase flow through deformable porous media. The experimental data and model predictions show good agreement, and suggest that it is important to consider the coupling between heating-and cooling-induced damage and flow properties to estimate brine inflow accurately. This modeling approach will be helpful for designing the cooling phase in salt repositories to minimize damage and brine inflow.

Summary: The Opalinus Clay is an important potential sealing horizon for radioactive waste repositories and carbon storage. Laboratory experiments show that relative humidity, grain size, and normal stress affect the frictional properties and stability of fault analogues. Increasing humidity decreases the friction coefficient and increases the stability parameter, while increasing normal stress leads to a transition from localized to distributed deformation.

Summary: Understanding the thermal effects on rock is critical for geothermal resource exploration and understanding Earth's temperature-driven evolution. This study observed the thermal-induced microcrack propagation of granite in real time using an ultrahigh-temperature instrument on an optical microscope. The experimental results revealed that microcracks initiate at 300°C and coalesce between 400 and 600°C, which is the main reason for the sharp decrease in macroscale mechanical properties of granite.

Summary: Global energy systems are transitioning to clean energy sources to reduce carbon dioxide emissions, necessitating the exploration and development of shale gas resources to support the global supply of natural gas. The challenge lies in the low permeability of shale, requiring large-scale volume fracturing to enhance connectivity. This study investigates the influence of a thin proppant layer on a single fracture and explores the effects of rock mineralogy, surface roughness, fluids, confining stress, time, temperature, and bedding on proppant embedment in Caney shale. The experiment revealed that fracture conductivity is primarily affected by proppant layer, roughness, mineralogy, fluids, temperature, and closure stress.

Summary: The current global energy supply is insufficient to meet the increasing demand, resulting in soaring energy prices. Shale oil and gas, although non-renewable, are relatively clean energy resources and still dominate the energy market. This paper investigates the stress-dependent changes in hydraulic conductivity and mechanical fracture-proppant interactions in Caney Shale, finding that proppant size is crucial for improving fracture conductivity.

Summary: Fault slip induced by fluid perturbation in shale formations can impact the integrity of shale caprocks for reservoirs holding buoyant fluids, and a better understanding of these processes is critical for reservoir monitoring. In this study, seismic responses of a shale fault exposed to fluid pressurization during an injection experiment were analyzed. Two types of seismic signals were observed: tremors associated with fluid-induced slip propagation, and micro-earthquakes triggered by stress perturbations. Tremors serve as a more direct observation for fluid-induced slip, providing a useful tool for monitoring fluid leakage and sealing integrity.

Summary: Rock salt is a potential host for heat generating nuclear waste due to its self-sealing capacity, low permeability, and high thermal conductivity. The geologic disposal of larger-sized canisters originally designed for spent fuel storage and transportation is being considered as a cost-effective alternative; however, their long-term vertical movement and low-stress creep behavior need to be evaluated. Different creep models were compared and the results showed that models calibrated only against high-deviatoric stress data might lead to inaccurate estimations of canister movement in salt formations.
