Geochemical Characteristics and Origins of the Crude Oil of Triassic Yanchang Formation in Southwestern Yishan Slope, Ordos Basin [PDF]
International Journal of Analytical Chemistry, 2017 Biomarker compounds that derived from early living organisms play an important role in oil and gas geochemistry and exploration since they can record the diagenetic evolution of the parent materials of crude oil and reflect the organic geochemical ...

Geometric Heterogeneity of Continental Shale in the Yanchang Formation, Southern Ordos Basin, China [PDF]
Scientific Reports, 2017 AbstractFavorable prospects for the exploration of shale gas have been demonstrated in the Ordos Basin, China. Outcrop and core observations indicate that there are abundant laminas in the shale strata, which exert a great influence on hydro-fracture propagation, gas storage and fluid flow.

Origin of Crude Oils in the Lower Yanchang Formation of Yan’an Area in Ordos Basin, China [PDF]
ACS OmegaThe clastic rocks of the Yanchang Formation in the Ordos Basin display poor physical properties but are rich in petroleum resources, exhibiting significant exploration potential. However, due to the existence of multiple sets of oil-bearing formations, hydrocarbon-generating formations, and a large longitudinal span, elucidating the correspondence ...
