Thermochemical sulfate reduction (TSR) is a set of redox reactions between organic matter
and sulfates at temperatures> 120° C, and occurs in varied environments including deeply …

Polycyclic aromatic sulfur heterocycles (PASHs), such as benzothiophenes (BTs),
dibenzothiophenes (DBTs), and benzonaphthothiophenes (BNTs), are found in crude oil …

Currently, there are very limited methods for direct gas-source rock correlation studies.
Herein, we applied sulfur isotope analyses of individual volatile organic sulfur compounds …

Abstract Throughout the Proterozoic Era, sedimentary organic carbon burial helped set the
pace of global oxygenation and acted as a major modulator of atmospheric CO 2 and …

Volatile organic sulfur compounds (VOSCs) may provide an alternative and improved
approach in the evaluation of source and thermal maturity of natural gas. However, the role …

Molecular and compound specific isotope analysis of volatile organic sulfur compounds
(VOSC), alkanes and CO 2 in natural gases from the Ordovician Majiagou Formation of the …

Improved understanding of the hydrogen sulfide (H 2 S) origins is of significant importance
for petroleum exploration, exploitation and refinement due to it being highly toxic and …

The objective of this work is to characterize the geochemistry of a suite of natural gas
samples from five fields in order to improve the understanding of the lacustrine petroleum …

The sulfate sources of thermochemical sulfate reduction (TSR) and hydrogen sulfide (H 2 S)
distributions in the Permian Changxing (P 2 c) and Triassic Feixianguan formations (T 1 f) in …

Methane dominated gas is one of the cleanest energy resources; however, there is no direct
method to determine its source rock. Natural gases produced from the eastern Sichuan …
