Characterization of lacustrine shale pore structure: The Upper-Triassic Yanchang Formation, Ordos Basin, China

Journal of Natural Gas Geoscience, 2016
AbstractAmounts of silty laminae in continental shale gas reservoir were investigated in the Zhangjiatan shale of the Yanchang Formation, Ordos Basin. The purpose of this study is to provide awareness in terms of the nature and discrepancies in pore structure between silty laminae and clayey laminae.

Constructing benzothiadiazole‐based donor‒acceptor covalent organic frameworks for efficient photocatalytic H2 evolution

Aggregate, Volume 6, Issue 1, January 2025.
A donor structural engineering strategy is proposed to construct donor–acceptor covalent organic frameworks (D–A COFs) for photocatalytic H2 evolution from water. By incorporating appropriate benzene moiety into the donor, the as‐obtained DHU‐COF‐BB exhibited a photocatalytic H2 evolution rate of 12.80 mmol g‒1 h‒1 and apparent quantum efficiency of 5 ...

Numerical Simulation Investigation of Fracture Propagation Behavior Patterns and Sensitivity Factors of Oil Shale Reservoirs in the Xunyi Region Considering the Influence of Natural Fracture

Geofluids, Volume 2025, Issue 1, 2025.
Shale oil and gas resources are considered one of the most important strategic resources globally today. However, the matrix permeability of oil shale reservoirs is extremely low, it requires modification through hydraulic fracturing technology to realize their economic and effective development.

Organic petrology of peak oil maturity Triassic Yanchang Formation lacustrine mudrocks, Ordos Basin, China

Interpretation, 2017
An organic petrology evaluation and a determination of solid bitumen reflectance [Formula: see text] were completed for organic-rich Triassic Yanchang Formation mudrocks ([Formula: see text]) from the Ordos Basin, north-central China, as part of a larger investigation of “shale gas” resources. These data were integrated with information from Rock-Eval

Comprehensive Evaluation Method of the Tight Oil Reservoir Quality in the Ordos Basin

Geofluids, Volume 2025, Issue 1, 2025.
The Wuqi area of the Ordos Basin boasts significant resource potential in the Chang 8 member of the Yanchang Formation. However, under the dual control of lithology and physical properties, reservoirs are generally dense and heterogeneous, and the quality of the oil layer changes rapidly, which brings difficulties to the optimization of favorable areas.

Comparison of hydrocarbon generation, expulsion periods, and accumulation periods of source rocks in Member 7 of the Yanchang Formation in the Jinghe Oilfield, southern Ordos Basin

地质科技通报
Objective Commercial oil accumulation in the Jinghe Oilfield of the Southwest Ordos Basin was primarily found in the Northeast area. Previous studies have shown that oil mainly sourced from the oil shale in Member 7 of the Yanchang Formation.
