Paleoclimatic evolution and its control on high-quality source rock development in the first member of the Qingshankou formation, Changling Sag, Songliao Basin: evidence from elemental geochemistry and palynology

Frontiers in Earth Science
The Cretaceous was a typical “greenhouse Earth” period. Understanding the paleoclimatic evolution of the first member of the Qingshankou Formation (Qing 1 Member) in the Changling Sag, Songliao Basin is crucial for revealing how continental basins ...

Machine learning method for lacustrine shale oil reservoirs: Improving movable fluid porosity prediction

Unconventional Resources
Movable fluid porosity (Φmf) is a key parameter to evaluate the seepage capacity and movable oil volume of shale reservoirs. Accurate measurement of the Φmf relies on expensive and time-consuming experimental methods, and little work has been done on ...
