As geochemical appraisals of mineral regions of commercial prospectivity evolve, the
organic matter associated with metal rich ores has attracted greater attention. Petroleum …

Methane is an important greenhouse gas and energy resource generated dominantly by
methanogens at low temperatures and through the breakdown of organic molecules at high …

The role of clay minerals in hydrocarbon generation is still debated. Although they are a
common component in lacustrine shales, few studies have examined their catalysis under …

Light hydrocarbons (LHs) are an important component of natural gas whose chemical and
isotopic compositions play a vital role in identifying gas genetic type, thermal maturity, gas …

Thermal maturity has a significant impact on hydrocarbon generation and the storage
capacity within shales, but explicit and quantitative characterization of that impact on …

Experiments were conducted to distinguish oil cracking in reservoir rock versus source rock.
Oil and source rock samples were heated in pressure vessels at 380° C for 72 h, which …

The phenomenon that laboratory pyrolysis experiments produce much wetter gases than
those in natural reservoirs is a long-recognized and debated problem in the investigation of …

Thermal cracking of complex organic matter can occur under many geological settings.
However, the role of thermal cracking vs. other chemistries (eg, metallic catalysis or Fischer …

To understand variations in geochemistry, organic petrology, and chemical composition of
crude oil and byproducts, an immature sample from the Cretaceous Qingshankou Formation …
