Multi‐factor coupling effects in hydraulic fracturing of laminated shale: Experimental insights and physics‐informed neural network‐driven optimization

Deep Underground Science and Engineering, EarlyView.
This study establishes a multi‐factor coupling framework for predicting breakdown pressure in laminated shale by integrating experimental hydraulic fracturing tests, physics‐informed neural networks (PINNs), and Sobol sensitivity analysis. It reveals how differential stress, the bedding dip angle, and the injection rate interact to influence fracture ...

Integrated numerical simulation and source‐sink matching methodology for Basin‐Wide CO2 storage assessment in depleted reservoirs: A Cambay Basin case study

Deep Underground Science and Engineering, EarlyView.
This study presents an integrated workflow to evaluate secure and large‐scale CO2 storage in depleted oil reservoirs of the Cambay Basin, India. Industrial CO2 sources are systematically matched with mature oil fields using a quantitative source–sink framework to minimize transport distance and cost.

Structural Health Monitoring of LNG Storage Tanks: A Method Based on Finite Element Seismic Response Analysis

Applied Sciences
Existing structural health monitoring of LNG (liquefied natural gas) liquid storage tanks is strictly constrained by explosion-proof safety and engineering conditions, making it impractical to achieve full-domain coverage through dense sensor deployment.

Characterization of seasonal glacial seismicity from a single-station on-ice record at Holtedahlfonna, Svalbard

Annals of Glaciology, 2019
Glacial seismicity provides important insights into glacier dynamic processes. We study the temporal distribution of cryogenic seismic signals (icequakes) at Holtedahlfonna, Svalbard, between April and August 2016 using a single three-component sensor ...

World's fastest 10 000‐m breakthrough: The XY‐22 well redefines deep‐earth access in the Tarim Basin

Deep Underground Science and Engineering, EarlyView.
The Tarim Basin in northwestern China hosts one of the world's deepest petroleum systems, exemplified by the XY‐22 ultra‐deep well (bottom depth: 11 116 m; ~220°C, ~145 MPa). This study integrates tectonic mapping, geological cross‐sections, ultraviolet fluorescence microscopy, and optical photothermal infrared (OPTIR) spectroscopy to characterize ...
