Geochemical Analysis of Mesozoic Oils in the Bonaparte Basin, Northwestern Australia

Isotopic and biomarker analyses characterize oil families within the Westralian Petroleum Supersystem. The study, presented at the 2000 AAPG International Conference, correlates oils from the Vulcan Sub-basin, ZOCA, and Browse Basin, identifying multiple families sourced from Jurassic and Early Cretaceous rocks. Data is provided by the Australian Ocean Data Network.

Use Cases

• Correlating oil families across different sub-basins based on isotopic and biomarker signatures mentioned in the description
• Modeling petroleum system evolution in the Bonaparte Basin based on identified Jurassic and Early Cretaceous source rocks
• Contrasting Mesozoic and Palaeozoic petroleum systems as described for the Petrel Sub-basin
• Statistical analysis of geochemical data to distinguish marine versus land-plant influenced oil families

Strengths

• Analysis is based on isotopic and biomarker data, which provides specific geochemical fingerprints.
• Study distinguishes at least four distinct oil families/sub-families with different source influences.
• Data provenance is linked to a specific 2000 AAPG International Conference presentation.

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/temporal bias inherent to data_gov_au.
