Regional Jurassic Sediment Depositional Architecture in the Browse Basin, Australia

A multi-disciplinary geological study from the Australian Ocean Data Network integrates sequence stratigraphy, palaeogeography, and geochemical data. The study maps the spatial and temporal distribution of Jurassic to earliest Cretaceous source rocks in the Browse Basin. This work aims to better understand the source rocks' contribution to known hydrocarbon accumulations, including the Ichthys and Prelude gas fields.

Use Cases

• Model petroleum charge history based on mapped Jurassic source rock distribution.
• Identify potential exploration targets based on the interpreted depositional environments of source rocks.
• Correlate geochemical fluid compositions to specific source rock intervals mentioned in the description.
• Analyze basin evolution based on the integration of sequence stratigraphy and palaeogeography.

Strengths

• Focuses on a basin with considerable gas and condensate resources, including the major Ichthys and Prelude LNG fields.
• Integrates multiple geological disciplines: sequence stratigraphy, palaeogeography, and geochemistry.
• Identifies specific source rock intervals (e.g., J10–J20, J30–K10) and their depositional settings.

Limitations

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