Browse Basin Petroleum Systems Analysis with Source Rock Maps and Fluid Composition

A study applying petroleum systems analysis to understand fluid sources and phase behavior in Australia's Browse Basin. The analysis maps source rock richness, thickness, and quality from well control and integrates property maps, basin-specific kinetics, and 3D surfaces. It was published by the Australian Ocean Data Network and last updated on 2026-04-10.

Use Cases

• Model hydrocarbon generation timing based on integrated source rock property maps and burial history models.
• Identify potential oil rims based on analysis of fluid phase behavior and dew point pressures.
• Correlate fluids to source rocks based on geochemical studies of gases and liquids.
• Assess regional maturity and expulsion history based on mapped source rock properties and kinetics.

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.
• Provides specific geological context, naming principal source rock formations and supersequences (e.g., Plover, Vulcan, Montara, Echuca Shoals).

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.
