Browse Basin Hydrocarbon Prospectivity Study for Northwest Australia

The Browse Basin offshore Northwest Australia is a proven hydrocarbon province. Geoscience Australia conducted a multi-disciplinary study integrating sequence stratigraphy, structural framework, biostratigraphy, well log analysis, seismic interpretation, and geochemical modeling to reassess petroleum systems and play types. The analysis covers seven Cretaceous supersequences from the late Tithonian to Maastrichtian.

Use Cases

• Modeling petroleum systems based on integrated geochemical and burial history data
• Identifying stratigraphic play types (e.g., basin-margin, clinoform topset, submarine fan) from cross-sections and maps
• Correlating hydrocarbon fluids with source rocks using molecular and isotopic geochemical fingerprints
• Assessing seal quality and reservoir-seal spatial relationships for prospect evaluation

Strengths

• Study integrates multiple disciplines: sequence stratigraphy, structural framework, biostratigraphy, well log analysis, seismic interpretation, and geochemistry.
• Analysis covers seven defined Cretaceous supersequences (K10–K60) and identifies four Mesozoic petroleum systems.
• Includes burial history modeling for Jurassic and Lower Cretaceous source rocks.

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 and HTML formats, which may require extraction for computational analysis.
