The study provides a comprehensive analysis of the natural gases from the Bonaparte, Browse, Carnarvon and Perth basins (in 4 modules). Geochemical analyses for the molecular and carbon isotope composition were performed on 96 gases and associated liquids, and these data are interpreted in a geological context. Additional non-exclusive data from the AGSO database have been used for correlation/interpretation purposes. The study addresses factors influencing the composition of gaseous and other light hydrocarbons in natural gas (and associated oil accumulations) including; - primary source and maturity controls, - secondary alteration processes, e.g. migration fractionation, water washing, biodegradation, and - multiple charge histories, including deep dry gas inputs.
