Genesis of H2S in Jurassic associated gas in Pengyang area, Ordos Basin, NW China

Journal of Natural Gas Geoscience, 2022
The Jurassic Yan'an Formation (J1y) crude oil-associated gas in the Pengyang area of the Ordos Basin contains a certain amount of H2S. The study of its genesis is important for us to predict the distribution of H2S in Mesozoic in the basin.

Development of Antifreezing High‐Efficiency Dust Suppressant for Railway Coal Transportation

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT In the process of railway coal transportation, a large amount of coal dust is dispersed, causing serious economic loss and environmental pollution. In order to improve the low‐temperature dust suppression performance, the present study has developed an antifreeze‐type, high‐efficiency railway coal transportation dust suppressant (hereinafter ...

Water‐Inrush Risk Assessment of Roof‐Confined Aquifer Strata Based on FAHP–RF Model in the Arid–Semiarid Ecotone: A Case Study of Zhuanlongwan Coal Mine

Geofluids, Volume 2026, Issue 1, 2026.
Water inrush poses a serious threat to the safety and sustainability of coal mining operations, particularly in arid–semiarid regions where confined aquifers overlie coal seams. Therefore, an accurate assessment of roof water inrush risk is essential to prevent water hazards on the roof.

Pore Structure of Tight Sandstones With Different Sedimentary Microfacies in the Chang 6–Chang 9 Layers, Triassic Yanchang Formation, Wuqi Area, Ordos Basin

Energy Science &Engineering, Volume 13, Issue 10, Page 4900-4916, October 2025.
Taking the Chang 6–Chang 9 layers in the Wuqi area of the Ordos Basin as a case study, this study investigates the pore characteristics of tight sandstones formed under different sedimentary microfacies. The results indicate that tight sandstones associated with distinct sedimentary microfacies exhibit significant variations in pore types, pore size ...
