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

Geoscience Australia conducted a multi-disciplinary study of the Browse Basin, a hydrocarbon province on Australia's North West Shelf. The work integrated updated biostratigraphy, well correlations, seismic interpretations, and geochemical analyses for ten Hettangian to Maastrichtian supersequences. This data was used to build a regional petroleum systems model identifying source rock distribution and play prospectivity.

Use Cases

• Modeling hydrocarbon generation and migration based on integrated biostratigraphy and seismic interpretations.
• Identifying prospective areas for liquid hydrocarbons within a gas-prone province based on geochemical analyses.
• Correlating petroleum systems and source rock units across different Jurassic–Cretaceous supersequences.
• Analyzing the influence of basin architecture and fluvial systems on source pod location and fluid composition.

Strengths

• Analysis covers ten distinct geological supersequences from Hettangian to Maastrichtian age.
• Integrates multiple data types including biostratigraphy, well correlations, seismic data, and geochemical analyses.
• Identifies 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 presented in PDF format, which may complicate direct computational analysis.
