Browse Basin Hydrocarbon Source Rock and Fluid Analysis, Australia

A petroleum systems analysis study from Geoscience Australia, last updated in April 2026, focusing on the source of fluids in the Browse Basin. The work maps source rock properties from well control and uses integrated modelling to provide insights into maturity, generation, and expelled fluid composition. Four Mesozoic petroleum systems have been identified in this offshore hydrocarbon province.

Use Cases

• Modeling hydrocarbon generation and expulsion timing based on integrated petroleum systems analysis.
• Mapping source rock richness and quality for basin-scale resource assessment.
• Analyzing fluid phase behavior and oil rim formation based on geochemical studies of gases and liquids.
• Correlating fluids to specific Jurassic and Cretaceous source rock formations mentioned in the description.

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 and characterizes principal source rocks from the Jurassic Plover, Vulcan, Montara, and Cretaceous Echuca Shoals formations.
• Provides a temporal model for hydrocarbon expulsion, indicating the majority occurred from the Late Cretaceous until present.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary file format is PDF, which may require extraction for computational analysis.
