The influence of 18α(H)-neohopane on source rocks in Yanchang formation, Ordos basin

Petroleum Science and Technology, 2017
Rock extracts and oil samples has been detected high abundance of 18α(H)-neohopane fromYanchang Formation in Ordos Basin. The results showed that the black mudstone was deposited in anoxic condition of semi-deep or deep lacustrine facie has low abundance of 18α(H)-neohopane in Chang 7 member.

Geochemical characteristics of the source rocks in Mesozoic Yanchang formation, central Ordos Basin

Journal of Earth Science, 2013
The shale of Yanchang Formation in Upper Triassic is the most important source rock for the Mesozoic petroleum reserviors in Ordos Basin. Chang 7 and Chang 4+5 members are the major source rock formation. Source rock samples, obtained from 22 cored wells in central Ordos Basin, were geochemically analyzed to determine the organic matter abundance ...

Identification and distribution of fractures in the Zhangjiatan shale of the Mesozoic Yanchang Formation in Ordos Basin

Interpretation, 2017
The natural fractures in mud or shale directly affect the quality and efficiency of shale gas reservoirs, and fracture identification and prediction play an important role in drilling shale gas wells and making plans for reservoir stimulation. We adopted ant tracking technology for 3D poststack reflective seismic waves to identify the size and ...
