Browse Basin Jurassic Sediment Architecture for Petroleum Systems Analysis

Geoscience Australia Data published a study on March 25, 2026, mapping the spatial and temporal distribution of Jurassic to earliest Cretaceous source rocks in the Browse Basin. The multi-disciplinary work integrates sequence stratigraphy, palaeogeography, and geochemical data to understand hydrocarbon charge history. The analysis identifies primary source rocks for gas and condensate accumulations, including the Ichthys and Prelude fields.

Use Cases

• Model petroleum system charge history based on mapped source rock distribution.
• Correlate geochemical fluid signatures to specific source rock intervals mentioned in the description.
• Identify exploration plays in underexplored areas based on the depositional architecture study.
• Analyze the relationship between rift systems and source rock deposition as described for the Heywood Graben.

Strengths

• Study integrates multiple disciplines: sequence stratigraphy, palaeogeography, and geochemistry.
• Focuses on a basin with considerable gas and condensate resources, including named fields like Ichthys and Prelude.
• Maps source rocks across a defined geological time range: Jurassic to earliest Cretaceous.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided as a PDF, which may require extraction for computational analysis.
