The transformation of kerogen to hydrocarbons in the early stages of oil generation is critical
for understanding the resource potential of liquid-rich shale plays. Organic petrology …

Hydrogen isotopic analysis of organic materials has been widely applied in studies of
paleoclimate, animal migration, forensics, food and flavor authentication, and the origin and …

The confined pyrolysis experiments of Kukersite kerogen in the presence and absence of
minerals and water revealed the effects of mineral acidity and water/OC ratio on the …

Micro-plugs of the Upper Devonian to Lower Mississippian Woodford Shale from the
Ardmore Basin in southern Oklahoma were analyzed before and after hydrous pyrolysis …

The role of carbon dioxide in regulating climate during the early Paleozoic, when severe
glaciations occurred during a putative greenhouse world, remains unclear. Here, we present …

The chemical analysis of carbonaceous and organic materials in geological samples (ie,
rocks) is an important and necessary step of hydrocarbon resource development. Despite …

Pyrolysis of Kukersite kerogen was conducted in gold capsules, with the yield and stable
carbon isotopic (δ 13 C) values of selected gas components (C 1, C 2, C 3, iC 4, nC 4, iC 5 …

Fossil fuel combustion is the dominant source of global sulfur dioxide (SO2) emissions. With
