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 ...

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 ...
