Analysis of Gas‐Bearing Properties of Shale Reservoirs: A Comprehensive Analysis Based on Field Interpretation and Logging Interpretation

Energy Science &Engineering, Volume 13, Issue 8, Page 4241-4251, August 2025.
ABSTRACT Shale gas, as an important component of unconventional natural gas, plays a crucial role in resource development. This paper proposes a comprehensive analytical method that combines field analysis and well logging interpretation to evaluate gas content in shale reservoirs.

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.

Accumulation condition for Wufeng-Longmaxi Formation shale gas of Yanjin-Gongxian area

工程科学学报, 2016
The formation conditions of shale gas in Wufeng-Longmaxi Formation of Yanjin-Gongxian area were analyzed on the basis of field observation and experimental data,and then the main factors for shale gas accumulation were discussed. Results show that black shale at the bottom of Wufeng-Longmaxi Formation is a deep-water shelf deposit product.
