The role of water in the laboratory thermal advancement of immature type I kerogen from the Cretaceous Qingshankou Formation in China. [PDF]

Sci Rep, 2023
AbstractTo understand variations in geochemistry, organic petrology, and chemical composition of crude oil and byproducts, an immature sample from the Cretaceous Qingshankou Formation in the Songliao Basin, China, was analyzed by anhydrous and hydrous pyrolysis (AHP/HP) at a wide range of temperatures ranging from 300 °C to 450 °C.
