Development or absence of conjugate fractures in low-permeability sandstones
Frontiers in Earth Science, 2023 Natural fractures are ubiquitous in rocks. The Coulomb law of Mohr’s failure theory predicts that the angle between conjugate failure surfaces is a constant. In the Ordos Basin, observing the development of two groups of conjugate fractures in the field,

Triassic hydrothermal chimneys from the Ordos Basin of Northern China [PDF]
Scientific Reports, 2021 AbstractBecause few well-preserved hydrothermal chimneys have been found in terrestrial sedimentary rocks, research on paleo-thermal vents in geological history is relatively sparse. In this study, we present our original discovery of “hydrothermal chimneys” from the Chang 7 source rocks of the Triassic Yanchang Formation in the Ordos Basin, China, and

Optimization of Production System of Shale Oil Development in Ordos basin, China
Scientific Reports, 2022 Abstract In this paper, production system(PS) of shale oil is optimized according to production data and indoor experiments, including core and fluid tests. Results showed that: ① Pressure drop rate at wellhead is a reasonable reference for the determination of post-fracture shut-in duration (PFSID).
