Depositional Framework of Petroleum Systems in Australia's Browse Basin

Geoscience Australia conducted a multi-disciplinary study of hydrocarbon sources and liquids prospectivity in the Browse Basin. The study integrated updated biostratigraphy, well correlations, seismic data, paleogeographic interpretations, and geochemical analyses across ten Hettangian to Maastrichtian supersequences. Results identify four geochemically distinct petroleum systems influenced by Jurassic-Cretaceous source pods and regional basin architecture.

Use Cases

• Model petroleum system generation and migration based on integrated biostratigraphy, seismic, and geochemical data.
• Identify high-graded areas for liquids prospectivity within a gas-prone province using play fairway interpretations.
• Correlate fluid compositions and source rock distributions across Jurassic and Cretaceous supersequences.
• Analyze the influence of entrenched fluvial systems and basin architecture on source pod compartmentalization.

Strengths

• Analysis covers ten distinct geological supersequences from Hettangian to Maastrichtian age.
• Study integrates multiple data types including biostratigraphy, well correlations, seismic data, and geochemical analyses.
• Results delineate four geochemically distinct petroleum systems within the basin.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF format, which may hinder direct computational analysis.
