Unconventional resources like shale gas has been the focus of intense research and
development for two decades. Apart from intrinsic geologic factors that control the gas shale …

Hydraulic fracturing has been widely used to enhance reservoir permeability during the
extraction of shale gas. As one of the external input parameters, injection rate has a …

Rock salt is a common sedimentary rock found in the crust and is widely used for
underground energy storage and waste disposal. This research conducted multi-stage cyclic …

Salt rock is a sedimentary rock that is widely distributed in the crust. Since salt rock has a low
permeability, rheological behavior, and self-healing characteristics, it has been extensively …

Rock salt, due to its water solubility, low permeability, high plasticity, and damage self-
healing ability, is one of the best candidate rock types for underground energy storage …

Hydrogen energy storage plays a crucial role in peak shaving of renewable energies, and
underground salt caverns are ideal locations for large-scale hydrogen storage. The …

Underground energy storage in salt caverns involves operating in high-temperature
conditions within deep strata, leading to unloading creep in the surrounding salt rock during …

Salt rock is characterized by a low porosity, low permeability and self-healing ability, and it is
one of the most common materials used for underground energy storage and construction in …

Underground salt rock caverns are ideal for national strategic energy storage, compressed
air energy storage, and CO 2 storage. Operation periods of salt cavern storage can be …

In the process of deep coal mining, the cyclic mining disturbance behavior produces
significant cyclic loading and unloading effects, to ensure safe production in the mining area …
