Petroleum Systems Analysis of the Browse Basin, Offshore Australia

The Browse Basin on Australia's North West Shelf is a proven hydrocarbon province. Geoscience Australia conducted a multi-disciplinary study integrating updated biostratigraphy, well correlations, seismic interpretations, and geochemical analyses to model regional petroleum systems. This work identifies source rock distribution, generation potential, and high-graded areas for liquids prospectivity within ten Hettangian to Maastrichtian supersequences.

Use Cases

• Modeling hydrocarbon migration pathways based on interpreted supersequence architecture and isochore maps.
• Identifying prospective areas for liquid hydrocarbons based on integrated geochemical and paleogeographic analyses.
• Correlating source rock units and fluid compositions across different graben systems like the Heywood Graben.
• Assessing the prospectivity of shallow plays in the southern Caswell Sub-basin based on the proposed migration and biodegradation scenario.

Strengths

• Analysis covers ten defined geological supersequences from Hettangian to Maastrichtian age.
• Integrates multiple data types including biostratigraphy, well correlations, seismic interpretations, and geochemistry.
• Identifies four distinct petroleum systems based on geochemical analysis and source pod compartmentalization.

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 require extraction for computational analysis.
