Browse Basin Petroleum Systems: Hydrocarbon Source Rock and Prospectivity Models

Geoscience Australia integrated updated biostratigraphy, well correlations, seismic, and geochemical analyses to model four distinct petroleum systems in the Browse Basin. The study identified multiple Jurassic–Cretaceous source rock units and high-graded areas for liquid hydrocarbons within a primarily gas-prone province. Results suggest shallow liquid-prone plays in the southern Caswell Sub-basin and on the basin margins.

Use Cases

• Model petroleum system evolution based on integrated biostratigraphy, seismic, and geochemical data.
• Identify prospective areas for liquid hydrocarbons based on interpreted source pod locations and depositional models.
• Correlate fluid composition and migration pathways using the regional supersequence framework.
• Assess the impact of regional basin architecture and fluvial systems on source rock distribution.

Strengths

• Analysis integrates ten Hettangian to Maastrichtian supersequences for a detailed chronostratigraphic framework.
• Study identifies four geochemically distinct petroleum systems based on source pod compartmentalization.
• Model incorporates multiple data types including isochore maps, depositional environmental models, and paleogeographic interpretations.

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.
