Browse Basin Hydrocarbon Source Rock Analysis And Petroleum Systems Model

A 2026 study by Geoscience Australia integrates updated biostratigraphy, well correlations, seismic interpretations, and geochemical analyses across ten Hettangian to Maastrichtian supersequences. The research models regional petroleum systems to understand source rock distribution, character, and generation potential in the Browse Basin. It identifies four distinct petroleum systems influenced by Jurassic–Cretaceous source pods and entrenched fluvial networks.

Use Cases

• Model hydrocarbon generation potential using geochemical analyses and source rock character data across supersequences.
• Correlate fluid composition and accumulation levels with specific source pods and supersequences like J10–J20 (Plover Formation).
• Map play prospectivity by integrating isochore maps, depositional environmental models, and paleogeographic interpretations.
• Analyze migration pathways and reservoir accumulation using data on basin architecture and entrenched fluvial systems.

Strengths

• Analysis covers ten Hettangian to Maastrichtian supersequences providing a broad stratigraphic framework.
• Integrates multiple data types including biostratigraphy, seismic interpretations, well correlations, and geochemical analyses.

Limitations

• Data is presented in a PDF format, limiting direct machine-readability and analysis.
• Specific sample sizes, row counts, and raw data volumes are not provided.
