Critical technologies in the construction of underground artificial chamber for compressed air energy storage systems

Deep Underground Science and Engineering, EarlyView.
This schematic illustrates an artificial chamber‐based compressed air energy storage system. Excess electricity compresses air into sealed underground chambers. During demand peaks, pressurized air is heated, expanded, and drives turbines to generate power.

The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations

Deep Underground Science and Engineering, EarlyView.
Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.

Investigation of damage impact on stability and airtightness of lined rock caverns for compressed air energy storage

Deep Underground Science and Engineering, EarlyView.
This study developed a thermo‐hydro‐mechanical damage coupling model for the compressed air energy storage (CAES) cavern and investigated the impact of damage to the surrounding rock and lining concrete on the stability and airtightness of the CAES cavern.

Gaborlet‐guided sparse filtering: A novel intelligent method for lithology identification by vibration signals while drilling

Deep Underground Science and Engineering, EarlyView.
The flowchart illustrates rock specimen testing, vibration signal acquisition, and feature extraction with Gaborlet and sparse filtering for classification. Abstract Traditional lithology identification methods mainly rely on core sampling and well‐logging data.
