Summary: This study presents an optimization framework for geologic CO2 storage under geomechanical risks, using coupled flow-geomechanics simulations to quantify risks and make optimal decisions. The results show that optimal decisions may differ when geomechanical risks are considered compared to simulations that only focus on flow dynamics.

Summary: The movement of injected CO2 in CO2 storage sites can affect the sealing performance of the cement sheath. The stability of the rock-cement-casing assemblage is influenced by both mechanical behavior and chemical alterations due to CO2 exposure. Different behavior is observed in injection wells and abandoned wells at different depths within the study.

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 study used an analytical approach to calculate the hoop and radial stresses of a small- or medium-scale CAES using salt domes at shallow depths, showing good matches for all tested parameters. It was found that mechanical stability at the crown of the storage cavity could be crucial for allowable storage pressure ranges, with higher K and W/H values advantageous for securing higher storage pressure. Energy storage capacities were estimated between 1 and 10 MJ/m(3) based on the analysis.

Summary: This study investigates the complex interaction between flow-transport-geomechanics-fracture mechanics and proposes a new computational framework to address these coupled problems. By modeling flow and transport processes in fractured porous media, and studying the response of fractures to flow-induced stress perturbations, the mechanisms of transport-geomechanics coupling are revealed. The applicability of the proposed framework is demonstrated through an experimental case study.

Summary: In this paper, the authors discuss the relationship between CO2 injection and the 2018 Hokkaido Eastern Iburi earthquake, suggesting that CO2 injection may cause groundwater anomalies and trigger earthquakes. However, they fail to provide quantitative evaluation supporting their conclusions. Through geomechanics model analysis, it is found that the impact of CO2 injection on the earthquake fault is lower than that caused by Earth tides, and there is no convincing mechanism for fluid channels to heal. Therefore, the occurrence of earthquakes is not related to CO2 injection.

Summary: A deep-learning-based surrogate model is proposed and applied for predicting flow and geomechanical responses in CO2 storage operations. The model combines deep convolutional and recurrent neural networks to capture the spatial and temporal distribution of saturation, pressure, and surface displacement fields. The results demonstrate high accuracy and significant uncertainty reduction in pressure buildup at the caprock.

Summary: This paper provides a new insight into the problem of crack propagation in elastic-plastic materials from the perspective of the critical elastic strain energy release rate G(e). The authors derive G(e) from the power balance during crack propagation, eliminating plastic dissipation, and assume it to be available for new crack formation. The assumption is validated through a series of experiments, showing that the critical elastic strain energy storage decreases linearly with crack length. Consequently, G(e) is believed to be a more intrinsic parameter for describing crack propagation in elastic-plastic materials.

Summary: A new discrete fracture model is implemented in the MATLAB Reservoir Simulation Toolbox to couple flow and geomechanical computations. Unstructured meshing is used for discretization, and the fluxes between different domains are computed explicitly. Flow calculations and geomechanical computations are solved sequentially, and several case studies demonstrate the utility of the coupling strategy. The model considers poroelasticity and stress/strain variation in fractured domains, and investigates factors influencing fracture interference behavior.

Summary: Depleted shale reservoirs have the potential to serve as long-term geological storage sites for CO2. However, the complex heterogeneity of shale matrix poses challenges in understanding CO2 transport behavior. In this study, a flow-coupled-geomechanical model is developed to analyze CO2 transport at the microscale, considering the deformation and interactions of both organic matter (OM) and inorganic matter (iOM). The results show that heterogeneity in the shale matrix leads to regional differences in CO2 transport and shale matrix deformation behavior, emphasizing the importance of considering matrix heterogeneity.

Summary: The mechanical behavior of hydrophilic and hydrophobic acrylates has been characterized using depth sensing indentation. Time-dependent behavior has been studied through load-relaxation tests. Finite element software and a visco-hyperelastic material model were used to simulate the experiments, with the model parameters determined using deep learning techniques. The developed material models were applied to mechanically simulate a standard compression test of a prototype intraocular lens.

Summary: A model is proposed to describe the hydromechanical behaviour of granular bentonite systems, which abstracts the system as a discrete set of bentonite units with homogeneous behaviour in continuum sub-domains. The model integrates the mass balance of each unit and applies advanced double porosity-based models to describe its stress-strain behaviour. The model is capable of reproducing the hydration process of a granular bentonite specimen and capturing the evolution of the integrated behaviour of the whole sample as well as the distribution of water content, dry density, and local vertical displacements.

Summary: A novel hydro-mechanical formulation is proposed to simulate the rapid wetting process of bentonite pellet fills. The model is based on a triple porosity concept but uses a double porosity structure for simplicity. The formulation assumes equal liquid pressure in the inter-pellet voids and boundary, allowing the same equation structure as double porosity approaches to be used. Despite its simplicity, the results for FEBEX and MX-80 bentonites are satisfactory.

Summary: A formulation is proposed to reproduce the hydro-mechanical behavior of compacted bentonites with negligible interaggregate porosity. The model assumes that the deformability of bentonite is controlled by the microstructural modeling level in a double porosity approach. The formulation has been experimentally validated and numerically verified, showing its practical interest and computational cost efficiency.

Summary: This study aims to assess the consistency in the modelling of thermo-hydraulic problems in clay-based engineered barriers. It focuses on modelling the vapour pressure as a function of temperature and the specific heat capacities of liquid water and water vapour. Various formulations of saturated vapour pressure and specific heat capacity values were evaluated, and recommendations for consistent modelling were made. The study found a suitable expression for saturated water vapour pressure and suggested constant values for specific heat capacity to maximize consistency.

Summary: This paper aims to develop a multi-scale chemo-mechanical material model to consider the active behavior of skeletal muscle in 3D geometries. Realistic muscle geometries and other tissues of the human abdomen were considered and an iterative algorithm was implemented to find the initial stress state that achieve the equilibrium of them with the intra-abdominal pressure. The calculated increase of intra-abdominal pressure by the model is consistent with reported experimental results, indicating the functionality of the proposed model.

Summary: A hydro-mechanical model of a heterogeneous granular bentonite mixture is presented in this study. The model incorporates the heterogeneity of the mixture by considering the potentially different percentage of megapores and grains in adjacent bentonite unit pairs. Mechanical contact is affected by the heterogeneity, and a strategy based on porosity values is proposed to control deformability.
