The organic-rich shale of the Upper Cretaceous Qingshankou Formation is an important hydrocarbon source rock in Northeast China. In this study, taking lacustrine as example, geochemical analysis, including total organic carbon (TOC), Rock-Eval pyrolysis, maceral compositions, X-ray diffraction (XRD), and biomarker analyses, were carried out on twenty-four samples to evaluate geochemistry enviro...

The Leg 104 organic geochemistry program consisted of monitoring (a) hydrocarbon gases, (b) organic and inorganic carbon, and (c) parameters resulting from Rock-Eval pyrolysis at three sites on the Vdring Plateau. The results amplify some of those obtained earlier on Deep Sea Drilling Project (DSDP) Leg 38. In a regional sense there is an inverse correlation between amounts of hydrocarbon gas a...

The study of organic matter content and composition in source rocks using the methods geochemistry is an important part unconventional reservoir characterization. aim this work was structural group analysis directly rock combination with a quantitative assessment surface distribution sample by FTIR spectroscopy microscopy. We have developed new experimental procedures for semi-quantitative cont...

The current study is devoted to the determination and interpretation of geochemical trends reflecting hydrocarbon generation, migration accumulation in unconventional reservoirs; performed on Bazhenov shale rock formation (Western Siberia, Russia). Results are based more than 3000 Rock-Eval analyses samples from 34 wells drilled central part West Siberian petroleum basin, which characterized by...

Five type II kerogens, shown by elemental analysis and Rock-Eval pyrolysis to represent a gradient of thermal maturity, were further characterized using a range of solid-state 13C NMR spectroscopic techniques. 13C cross polarization (CP) NMR spectra of the kerogens confirmed the well-established pattern of increasing aromaticity with increasing thermal maturity. Spin counting showed that CP obs...
