Geochemical Analysis of Mesozoic Oils in the Bonaparte Basin, Australia

The Australian Ocean Data Network provides a dataset from a 2000 study analyzing Mesozoic petroleum systems in the Bonaparte Basin. The study uses isotopic and biomarker analyses to characterize oil families within the Westralian Petroleum Supersystem, correlating oils across sub-basins. It identifies multiple oil families sourced from Jurassic and Early Cretaceous rocks.

Use Cases

• Correlating oil families across basins based on isotopic and biomarker signatures described in the study.
• Modeling petroleum systems in the Bonaparte Basin based on identified source rocks like the Lower Vulcan Formation.
• Classifying oils by geochemical signature, such as land-plant influenced or marine influenced families mentioned in the description.
• Contrasting Mesozoic and Palaeozoic petroleum systems as referenced in the study's scope.

Strengths

• Analysis is based on specific geochemical methods: isotopic and biomarker analyses.
• Study identifies four distinct oil families/sub-families with different source influences.
• Data is associated with a specific scientific presentation at the 2000 AAPG International Conference.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on the Bonaparte Basin.
