Geochemical Analysis of Mesozoic Oil Families in Bonaparte Basin

Isotopic and biomarker analyses characterize multiple oil families within the Westralian Petroleum Supersystem. The study correlates oils across the Vulcan Sub-basin, Zone of Co-operation, and Browse Basin, identifying sources from Jurassic and Early Cretaceous rocks. Findings were presented at the 2000 AAPG International Conference and are hosted by the Australian Ocean Data Network.

Use Cases

• Correlate oil families across Vulcan Sub-basin, ZOCA, and Browse Basin using isotopic and biomarker signatures.
• Distinguish land-plant influenced oils from marine influenced oils using geochemical end-member analysis.
• Identify source rocks for condensates, such as the marine carbonate signature from Sunrise-1.
• Contrast Mesozoic petroleum systems with Palaeozoic systems in the Petrel Sub-basin using geochemical data.

Strengths

• Analysis identifies four distinct oil families/sub-families with specific geochemical signatures.
• Study correlates data across multiple sub-basins and geological formations.

Limitations

• Data is presented in PDF/HTML formats, limiting direct computational analysis.
• The study's primary data and sample sizes are not provided.
• Findings are from a conference presentation in 2000, potentially representing outdated interpretations.
