Browse Basin Petroleum Systems Analysis for Hydrocarbon Source and Phase Behavior

A study applying petroleum systems analysis to understand fluid sources and phase behavior in Australia's Browse Basin. The analysis maps source rock properties from well control and integrates basin-specific kinetics with 1D and 3D models. The dataset, published by the Australian Ocean Data Network, was last updated on 2026-06 27.

Use Cases

• Model hydrocarbon generation and expulsion timing based on integrated source rock maturity maps and burial history models.
• Identify potential oil rim formations based on analysis of fluid phase behavior and dew point pressures.
• Correlate fluids to specific Mesozoic source rock intervals based on geochemical studies of gases and liquids.
• Map the distribution and quality of Jurassic-Cretaceous source rocks based on well control data.

Strengths

• Analysis integrates multiple data layers: source rock property maps, basin-specific kinetics, 1D burial history, and regional 3D surfaces.
• Identifies four distinct Mesozoic petroleum systems within the basin.
• Provides specific geological context, naming principal source rock 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 PDF format, which may require extraction for computational analysis.
