Abstract

Abstract

The study of position-specific isotopes in natural gas propane is becoming a new hotspot in petroleum geochemistry. In this paper it summarizes advancements in analytical techniques for determining position-specific isotope compositions of propane in natural gas and examines the controlling mechanisms of position-specific isotope distributions in natural gases, which provides a novel means to trace hydrocarbon generation pathways, expulsion-retention processes and secondary alteration. By applying position-specific isotope signatures of propane desorbed from source rock, gas source correlation can be achieved, especially in basins with multiple adjacent source rock intervals. In summary, position-specific isotopes of propane provide a powerful tool for elucidating the formation, evolution, and alteration processes of natural gases. Further studies should integrate compound-specific isotope of alkane gases and clumped isotope of methane to extend its application to more complex geological systems.
