Browse Basin Petroleum Systems Analysis for Hydrocarbon Source and Phase Behavior

The Australian Ocean Data Network provides a petroleum systems analysis of the Browse Basin, offshore Australia's North West Shelf. The study maps source rock properties and uses 1D and 3D modeling to provide insights into maturity, hydrocarbon generation, and expelled fluid composition. The data was last updated on June 5, 2026.

Use Cases

• Modeling hydrocarbon generation and expulsion timing based on integrated petroleum systems analysis.
• Mapping source rock richness, thickness, and quality for basin-scale resource assessment.
• Analyzing the phase behavior of fluids (oil rims, gas-condensate) based on geochemical studies of gases and liquids.
• Identifying and characterizing Mesozoic petroleum systems from combined geochemical and geological data.

Strengths

• Analysis integrates multiple data types: source rock property maps, basin-specific kinetics, 1D burial history models, and regional 3D surfaces.
• Identifies four distinct Mesozoic petroleum systems within the basin.
• Specifies principal source rock formations (Plover, Vulcan, Montara, Echuca Shoals) and their geological ages.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
