Gas-in-Place (GIP) Variation and Main Controlling Factors for the Deep Wufeng-Longmaxi Shales in the Luzhou Area of the Southern Sichuan Basin, China

, 2023
The Wufeng-Longmaxi Formation shales with burial depths > 3 500 m in the southern Sichuan Basin are believed to have large shale gas potentials. However, the reservoir properties and gas-in-place (GIP) contents of these shales exhibit variations across ...

Quantifying Natural Hydrogen‐Helium Sources and Dynamic Accumulation in Global Sedimentary Basins

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract Despite the scientific and economic importance of hydrogen and helium, their crustal budgets remain poorly quantified. This study systematically assesses the accumulation of natural hydrogen and helium in global sedimentary basins by integrating predictive models for both gases with H2/He ratios.

Prediction of Fault and Fracture Density From Seismic Attributes and Machine Learning Models Calibrated With Borehole Image Logs

Basin Research, Volume 38, Issue 3, May–June 2026.
This study integrates post‐stack seismic attributes with a CNN‐based workflow to characterize sub‐seismic deformation in shale gas reservoirs. A near‐linear correlation is established between seismic characterization methods and borehole deformation counts.

Precise Characterization of Fluid Logging Responses in Complex Shale Reservoirs: A Case Study From the Hongxing Area, Eastern Sichuan Basin

Geofluids, Volume 2026, Issue 1, 2026.
Precise characterization of fluid‐sensitive logging responses in complex shale reservoirs is very important. It is essential for quantitative formation evaluation and development optimization. Based on a case study of the shale gas reservoir in the second member of the Wujiaping formation (hereinafter referred to as the Wu‐2 Member) in the Hongxing ...

Development Characteristics and Distribution Patterns of Fractures in the Wufeng-Longmaxi Formation Shale in the Southwestern Sichuan Basin, China

Lithosphere, 2022
Abstract As the important storage space and main seepage channel of the shale gas reservoirs, fractures control the migration, enrichment, and preservation of shale gas. Therefore, studying the development characteristics of fractures within shale is the key to the exploration and development of shale gas reservoirs.

Full‐Scale Pore Structure Characterization of the Late Permian Dalong Shale in Western Hubei, Southern China

Geofluids, Volume 2026, Issue 1, 2026.
The Late Permian Dalong Formation in western Hubei has recently been recognized as a promising target for shale gas development. However, the comprehensive characterization of its pore structure remains limited. To elucidate the pore system of the Dalong shale, an integrated experimental approach was applied to outcrop‐derived samples.
