Depositional framework of petroleum systems, Browse Basin, offshore North West Shelf, Aust

A multi-disciplinary study by Geoscience Australia integrating updated biostratigraphy, well correlations, seismic interpretations, and geochemical analyses for ten Hettangian to Maastrichtian supersequences. The data was used to build a regional petroleum systems model identifying four distinct systems and source rock distribution within the Browse Basin, offshore North West Australia. The dataset is provided by the Australian Ocean Data Network and was last updated on 2026-04 10.

Use Cases

• Modeling hydrocarbon migration pathways based on isochore maps and depositional environmental models
• Identifying liquid-prone plays based on geochemical analyses of distinct petroleum systems
• Correlating source rock generation potential across Jurassic–Cretaceous supersequences
• High-grading exploration areas based on integrated paleogeographic and play fairway interpretations

Strengths

• Integrates multiple data types including biostratigraphy, seismic, well correlations, and geochemical analyses
• Covers ten supersequences from Hettangian to Maastrichtian, providing a broad stratigraphic framework
• Identifies four geochemically distinct petroleum systems with specific source pod locations

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 require extraction for computational analysis
