Browse Basin Petroleum Systems Analysis of Source Rocks and Fluids

A study from Geoscience Australia applying petroleum systems analysis to understand fluid sources and phase behavior in the Browse Basin offshore Australia. The work integrates source rock property maps, basin-specific kinetics, and burial history models to identify four Mesozoic petroleum systems. The principal source rocks are Jurassic to Cretaceous formations containing land-plant derived organic matter, with most hydrocarbon expulsion occurring from the Late Cretaceous to present.

Use Cases

• Modeling hydrocarbon generation and expulsion timing based on source rock maturity maps.
• Predicting fluid phase behavior (oil rims vs. gas-condensate) based on integrated petroleum systems analysis.
• Correlating discovered fluids to specific source rock intervals based on geochemical studies.
• Assessing basin-scale oil potential in regions with gas-prone source rocks.

Strengths

• Analysis identifies four distinct Mesozoic petroleum systems.
• Study integrates multiple data types: source rock property maps, basin-specific kinetics, 1D burial history, and 3D surfaces.
• Principal source rocks are specified as Jurassic and Cretaceous formations (Plover, Vulcan, Montara, Echuca Shoals).

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 a PDF format, which may require extraction for computational analysis.
