Carbon isotope evidence for shale gas preservation conditions and large methane release over million years: A case study of shale gas reservoirs of Wufeng and Longmaxi Formations in the Sichuan Basin

[Display omitted] •Isotope reversal reflects the preservation conditions and gas content of shale gas.•The calculation formula of shale gas well's recoverable reserves is established.•The massive release of global methane enriched in shale is predicted. Although carbon isotope reversal and its...
