Special Issue Information

Dear Colleagues,

With the increasing global demand for low-carbon and sustainable energy systems, geological storage and engineering application of gases such as CO2, natural gas, and hydrogen have become critical frontiers in energy and environmental research. Technologies like carbon capture, utilization, and storage (CCUS), underground gas storage (UGS), and geological hydrogen storage (GHS) are essential for achieving carbon neutrality, ensuring energy security, and supporting the transition to renewable energy.

This Special Issue aims to showcase the latest scientific and engineering advancements in geological storage mechanisms, reservoir characterization, wellbore–reservoir coupling, multiphysics modeling, and field-scale applications across different gas storage technologies. We welcome contributions addressing the challenges and opportunities in gas injection, migration, containment, monitoring, and long-term storage safety, as well as innovative strategies to improve storage efficiency and economic feasibility.

Original research articles, reviews, and case studies that explore cross-cutting themes, such as geomechanics, chemical reactions, and digital technologies in gas storage systems, are particularly encouraged.

We invite researchers from academia, industry, and government to contribute their latest findings to advance this interdisciplinary and impactful field.

Prestack seismic waveform inversion starts with an initial model and computes synthetic or predicted seismic data using a wave equation-based approach. Then, by matching these predicted data with the observed seismic data, it iteratively modifies the initial model using an optimization method until the predicted and observed data reasonably match. This method has been demonstrated to be superior to amplitude-variation-with-angle inversion. Because of the wave equation-based approach, computational cost is, however, one major drawback of the method. In the presence of well-logs with borehole measurements of the subsurface properties such as the P-wave velocity, S-wave velocity, and density, it is possible to provide a good initial model, and the method quickly converges to the true model at well locations. However, for locations away from the wells, the initial models are obtained by interpolating the initial models at the well locations over the interpreted geological horizons. These models can be far from the true models and inverting prestack data for these locations using wave equation-based method is computationally challenging. Because of these computational challenges, amplitude-variation-with-angle inversion is the current state-of-the-art method for routine seismic inversion applications. In this work, we provide an attribute-guided framework to generate initial models and demonstrate its applicability, which can potentially overcome computational challenges of prestack seismic waveform inversion. Furthermore, we also discuss the feasibility of using this attribute-guided approach to characterize reservoirs for underground hydrogen storage. Full article

Underground hydrogen storage (UHS) in saline aquifers offers a viable alternative to surface-based storage systems, which are limited by capacity constraints, high operational pressures, complex thermal regulation, low energy densities, and potential safety hazards. This study uses a fully compositional reservoir simulation model to evaluate hydrogen behavior in the Mt. Simon Sandstone in the Illinois Basin. The analysis focuses on the effects of hysteresis, solubility, diffusivity, and production well perforation location on recovery efficiency. Cyclic injection and withdrawal scenarios were simulated to assess storage performance and operational strategies. The results show that accounting for hydrogen diffusivity shows essentially unchanged withdrawal efficiency at 79%, the same as the base case. Solubility causes a slight decrease to 78%, while hysteresis leads to a more significant reduction to 63%. The location of injection well perforations also influences recovery: top-perforated wells increase efficiency from 60% after the first cycle to 74% after six cycles, whereas bottom-perforated injection wells increase efficiency from 56% to 79% over the same period. These findings emphasize the importance of accounting for multiphase flow dynamics and strategic well placement in optimizing UHS system performance. The insights contribute to advancing reliable, large-scale hydrogen storage solutions essential for supporting renewable energy integration and long-term energy security. Full article

Carbon Capture and Storage (CCS) is a critical technology for promoting carbon reduction and achieving the carbon neutrality goal. As a vital component of CCS projects, the injection process makes it especially important to clarify wellsite layout methods, wellbore parameters, and injection parameters for the safe and efficient storage of CO2. This article presents a survey of engineering parameter design in typical domestic and international comprehensively compares and analyzes multi-dimensional parameters under different storage conditions such as saline aquifers and basalt, and clarifies the basic adaptation logic that storage types determine engineering parameters, the requirement that engineering designs should be formulated according to reservoir characteristics, and the need for dynamic adjustment of engineering parameters based on actual conditions. Meanwhile, the paper identifies various challenges, including geological hazards in wellsite selection, wellbore corrosion risks, loss of control over injection pressure, and storage safety, corrosion risks, and CO2 leakage risks caused by thermodynamic phase transitions. It puts forward suggestions such as risk prevention and control strategies, wellbore integrity guarantee systems, injection optimization methods, and leakage prevention and control systems, providing a basis for the engineering design and safety assessment of CCS projects.
