Abstract:

Current levels of anthropogenic carbon dioxide in the atmosphere are responsible for global warming at scales not seen before. To mitigate this global warming trend, the Intergovernmental Panel on Climate Change (IPCC) has universally adopted the geological carbon storage option. The technical implication of geological carbon storage is that carbon dioxide with a very low dynamic viscosity will be injected to push formation brine with a high viscosity contrast. Consequently, problems of interfacial instability responsible for poor sweep efficiencies encountered in the petroleum industry’s impr

Abstract:

Salt caverns serve as underground storage for crude oil, natural gas, compressed air, carbon dioxide, and hydrogen. Key stages of cavern development for storage purposes include design, construction, storage, and abandonment. The design phase addresses optimal cavern shape, size, pillar dimensions, number of caverns, the impact of interbeds, and cyclic loading while considering the creep behavior of salt and the mechanical behavior of surrounding layers. During this phase, geological factors such as depth, thickness, and the quality of salt are considered. For construction, two main methods—di

Abstract:

Addressing the critical challenges of sealing integrity and operational optimization in aquifer gas storage (AGS), this study focuses on a block within the Qianjiang Basin to systematically investigate geological modeling and injection–production strategies. Utilizing 3D seismic interpretation, drilling, and logging data, a stochastic geological modeling approach was employed to construct a high-resolution 3D reservoir model, elucidating the distribution of reservoir properties and trap configurations. Numerical simulations optimized the gas storage parameters, yielding an injection rate of 16

Abstract:

Many minerals are susceptible to environmental conditions; for example, several sulfates are prone to dehydration under low relative humidity. As such, the appropriate storage conditions required by minerals are species-specific. In an example presented here, stalactitic specimens previously thought to have been melanterite (a hydrated iron sulfate) from the South Wales Coalfield in the collections at National Museum Cardiff (NMC) were recently identified as being dominated by magnesium and aluminium sulfate species of various hydration states.

Abstract:

Ash storage sites are a commonly used method of disposing fly ash, a byproduct of coal combustion, in China today, and when it accumulates to a certain height, serious geological hazards may occur as a result of seismic activity. In this study, an in situ standard penetration test was carried out on a constructed ash storage site in Northwest China to evaluate the potential for liquefaction of alluvial fly ash within the site, and the results show that dynamic liquefaction can occur within a newly constructed three-stage subdam.

Abstract:

Carbon sequestration in the sea area, with the advantages of high storage potential, high safety, low environmental impact, and a long storage period, serves as an important way to achieve the goals of “carbon peaking and carbon neutrality”. The East China Sea Shelf Basin has a large area, and the target layer of carbon storage has a large thickness and wide distribution. Due to the high tectonic stability of the basin and the absence of earthquakes of magnitude 7 or higher, the basin is a subcooled–subthermal basin in terms of geothermal field characteristics. In addition, the basin has a hig

Energy storage systems are gaining increasing attention as a solution to the inherent intermittency of renewable energy sources such as solar and wind power. Among large-scale energy storage technologies, compressed air energy storage (CAES) stands out for its natural sealing properties and cost-efficiency. Having abundant salt resources, the thick and regionally extensive salt deposits in Unit B of Southern Ontario, Canada, demonstrate significant potential for CAES development. In this study, optimization for essential CAES salt cavern parameters are conducted using geological data from Unit

Geological sequestration of CO2-rich gas as a CO2 capture and storage technique has a lower technical and cost barrier compared to industrial scale-up. In this study, we have proposed CO2 capture and storage via hydrate in geological formation within the hydrate stability zone as a novel technique to contribute to global warming mitigation strategies, including carbon capture, utilization, and storage (CCUS) and to prevent vast methane release into the atmosphere caused by hydrate melting. We have attempted to enhance total gas uptake and CO2 capture efficiency in hydrate in the presence of ki

Abstract:

Gel systems are widely used as plugging materials in the oil and gas industry. Gas channeling can be mitigated by reducing the heterogeneity of the formation and the mobility ratio of CO2 to crude oil. Cracks and other CO2 leaking pathways can be plugged during the geological storage of CO2 to increase the storage stability. By adding CO2-responsive groups to the classic polymer gel’s molecular chain, CO2 responsive gel is able to seal and recognize CO2 in the formation while maintaining the superior performance of traditional polymer gel. The application of CO2 responsive gels in oil and gas
