Browse Basin Petroleum Systems: Depositional Framework and Hydrocarbon Prospectivity

A multi-disciplinary study by Geoscience Australia integrates updated biostratigraphy, well correlations, seismic, paleogeographic, and geochemical analyses for ten Hettangian to Maastrichtian supersequences. This regional petroleum systems model identifies source rock distribution, generation potential, and play prospectivity within the Browse Basin. The analysis delineates four geochemically distinct petroleum systems influenced by Jurassic–Cretaceous source pods and regional basin architecture.

Use Cases

• Modeling hydrocarbon migration pathways based on interpreted supersequence architecture and source pod compartmentalization.
• Evaluating liquids prospectivity in gas-prone provinces using integrated geochemical and paleogeographic interpretations.
• Correlating fluid compositions and reservoir characteristics across different stratigraphic levels and sub-basins.
• Identifying shallow liquid-prone plays in basin margins using the proposed scenario of Cretaceous-sourced liquid mobilization.

Strengths

• Analysis integrates ten defined supersequences (Hettangian to Maastrichtian) for a structured temporal framework.
• Model identifies four distinct petroleum systems based on geochemical and depositional data.
• Study covers multiple proven hydrocarbon accumulations, including Ichthys/Prelude and Burnside.

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.
