The natural cracking of crude oils in deep reservoirs has gained great interest due to
continuously increasing depth of petroleum exploration and exploitation. Complex oil …

Recently developed methane clumped isotope techniques provides fresh and novel insights
into methane biogeochemistry, which have been unobtainable through other techniques …

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 …

Microbial anaerobic oxidation of methane (AOM) substantially mitigates atmospheric
methane emissions on Earth and is a process to consider for astrobiological targets where …

Evaluating the origin and fate of hydrocarbons holds significance in many fields, such as
energy, geology, astrobiology, biosphere, and environment. However, challenges arise in …

Gas hydrates stored in the continental margins of the world's oceans represent the largest
global reservoirs of methane. Determining the source and history of methane from gas …

Coalbed gas (CBG) is an unconventional natural gas with a large resource potential. In
order to determine its origins, formation pathways and mechanisms, studies on the …

Methane (CH4) is a matter of environmental concern; however, global methane
isotopologue data remain inadequate. This is due to the challenges posed by high …

Abstract The Tarim Basin is one of the most complex, ancient, and petroliferous deep craton
basins in the world. Multiple sets of source rocks, stages of tectonism, and episodes of …

Intramolecular or position-specific carbon isotope analysis of propane (13CH3–12CH2–
12CH3 and 12CH3–13CH2–12CH3) provides unique insights into its formation mechanism …
