Exploring the Effects of Hydraulic Fracturing on the 2019 Mw 5.0 Weiyuan Earthquake in Sichuan, China

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract The seismicity inside the Sichuan Basin in southwest China has been dramatically intensified with the increase of shale gas exploitation recently. On 8 September 2019, an MW 5.0 earthquake struck Weiyuan County in the Sichuan Basin, representing the largest earthquake in the Weiyuan shale gas field.

A novel method for automatic quantification of different pore types in shale based on SEM-EDS calibration [PDF]

Pore type is a crucial consideration in the quantification of shale pores. Convolutional Neural Networks (CNNs) are widely used for identifying pore types in shale, but it is hampered by feature extraction bias, difficult data labeling, and poor ...

Research on the Micromechanical Properties of Minerals and Their Interfaces in Fractured Shale Reservoirs

Energy Science &Engineering, Volume 13, Issue 8, Page 4032-4045, August 2025.
ABSTRACT The mechanical properties of shale are key parameters affecting shale reservoirs. They influence the gas content in the shale reservoirs, expansion of hydraulic fractures, and microscopic changes in the in‐situ stress. In this paper, the shale of Longmaxi Formation in Changning area of Sichuan Basin is taken as the research object.

New Pattern of Uplift‐Depression of the Pre‐Cambrian Basement in the Sichuan Basin: Constraints From Multi‐Seismic Parameter Imaging

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract The structural configuration of the pre‐Cambrian basement in the Sichuan Basin, a highly promising region for hydrocarbon exploration, has been a subject of long‐standing debate. Here, we determined the fine‐scale three‐dimensional seismic models of the Sichuan Basin using 187,356 high‐quality P‐ and S‐wave travel time pairs recorded by 627 ...
