Regional Jurassic Sediment Architecture in Browse Basin for Petroleum System Analysis

A multi-disciplinary study integrating sequence stratigraphy, palaeogeography, and geochemistry has mapped Jurassic to earliest Cretaceous source rocks in the Browse Basin. This analysis from the Australian Ocean Data Network provides insights into the source contributions and charge history for major gas and condensate resources, including the Ichthys and Prelude fields. The study delineates the spatial and temporal distribution of organic-rich rocks within specific supersequences and formations.

Use Cases

• Modeling hydrocarbon charge history based on mapped source rock distribution.
• Identifying exploration targets based on the interpreted depositional environments for source rocks.
• Correlating geochemical fluid compositions to specific source intervals mentioned in the description.
• Assessing petroleum system potential in underexplored areas like the Heywood Graben or southern Caswell Sub-basin.

Strengths

• Study integrates multiple geological disciplines: sequence stratigraphy, palaeogeography, and geochemistry.
• Focuses on a basin with considerable gas resources, including the named Ichthys and Prelude LNG fields.
• 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 presented in PDF format, which may require extraction for computational analysis.
