Browse Basin Petroleum Systems Analysis with Depositional Models

Geoscience Australia conducted a multi-disciplinary study of hydrocarbon sources in the Browse Basin, offshore North West Shelf, Australia. Updated biostratigraphy, well correlations, seismic interpretations, and paleogeographic models were integrated for ten Hettangian to Maastrichtian supersequences. The analysis identified four geochemically distinct petroleum systems influenced by Jurassic–Cretaceous source pods and regional basin architecture.

Use Cases

• Model hydrocarbon generation potential based on integrated biostratigraphy and seismic interpretations
• Identify liquid-prone plays based on depositional environmental models and source pod compartmentalization
• Analyze fluid composition and migration pathways based on supersequence correlations and geochemical analyses
• Evaluate regional basin architecture influence on source rock distribution based on entrenched fluvial system models

Strengths

• Analysis integrates updated biostratigraphy, well correlations, seismic, and paleogeographic interpretations
• Petroleum systems model covers ten supersequences from Hettangian to Maastrichtian
• Study identifies four geochemically distinct petroleum systems with compartmentalized source pods

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 format, which may require extraction for computational analysis
