Study on the Mechanical Properties and Fracturing Damage Process of Shale With Preexisting Fractures Under Fluid–Solid Coupling Effects

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
To investigate the influence of fractures on the hydraulic fracturing extraction of shale gas, this study conducted a fluid–solid coupling analysis of shale with preexisting fractures. Initially, the mineral composition and the distribution of microfractures and pores in the shale were analyzed using X‐ray diffraction (XRD) and argon ion scanning ...

Black Shale Lithofacies of the Wufeng–Longmaxi Formation in the Southeast Margin of Chongqing, China

Geofluids, Volume 2025, Issue 1, 2025.
China’s shale gas has undergone nearly 20 years of exploration; unconventional oil and gas geological evaluation theories and research methods have been greatly enriched, but how to quickly, conveniently, and accurately identify the sweet spots of shale gas is still puzzling many researchers. This study focuses on the black shale of the Wufeng–Longmaxi
