Methodologies for Gas Content Evaluation in Deep Coal/Shale Formations: Assessment, Improvement, and Comparison

Journal of GeoEnergy, Volume 2026, Issue 1, 2026.
Gas‐in‐place (GIP) content is a critical indicator for evaluating deep coal/shale resource potential, typically categorized into lost gas content, desorbed gas content, and residual gas content. The lost gas content cannot be directly quantified and requires specific methods for assessment.

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 ...
