Microscopic Pore Structure Characteristics and Genesis of Low Resistivity Reservoirs: A Case Study of the Wufeng and Longmaxi Formations in the Changning Area, Sichuan Basin

Energy Science &Engineering, Volume 13, Issue 12, Page 5910-5923, December 2025.
1. Organic matter graphitization forms highly conductive carbon networks, significantly reducing shale resistivity. 2. Major and trace elements further enhance conductivity through electron transfer and electrochemical reactions. ABSTRACT This study investigates the micro‐pore structure characteristics and genesis of low‐resistivity reservoirs in the ...

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.

Discussion on the characteristics and controlling factors of differential enrichment of shale gas in the Wufeng-Longmaxi formations in south China

Journal of Natural Gas Geoscience, 2020
Abstract The annual output of shale gas from the Wufeng-Longmaxi formations in South China reached 15.4 × 109 m3 in 2019, which makes Sichuan basin the second-largest shale gas producing area in the world. Based on the data of more than 1000 shale samples of the Wufeng-Longmaxi formations taken from typical drilling and outcrop profiles in the ...

Effects of Periodic Normal Stress Oscillations on Frictional Properties of Simulated Natural Fault Gouges Under In Situ P‐T Conditions

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Induced earthquakes are occasionally associated with stress oscillations resulting from periodic industrial activities. Yet, the effects of stress oscillations on fault friction under realistic subsurface conditions are not fully clear. We conducted normal stress oscillations experiments using simulated fault gouges derived from the major ...

Multi‐Criterion Stability Evaluation and Surface Boundary Method for Slopes

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Slope failure generally starts from a single point, where a local failure surface forms, and then progresses to the overall failure. Based on this behavior, this paper proposes a multi‐criterion stability evaluation approach for describing progressive failure process of slope.

Using nanoindentation to quantify the mechanical profile of the Wufeng–Longmaxi Formation in southwestern China: link to sedimentary conditions

Solid Earth
The fine construction of a continuous mechanical profile for the Wufeng–Longmaxi (WF-LMX) Formation is crucial for designing hydraulic fracturing projects in shale gas development, which however is generally difficult to achieve by conventional macroscopic mechanical testing methods due to the difficulty in obtaining continuous block shale samples ...
