Jurassic Sediment Depositional Architecture in the Browse Basin

A multi-disciplinary study integrating sequence stratigraphy, palaeogeography, and geochemical data maps the spatial and temporal distribution of Jurassic to earliest Cretaceous source rocks in the Browse Basin. The research, published by the Australian Ocean Data Network, allows a better understanding of source rock contributions to known hydrocarbon accumulations, including the Ichthys and Prelude LNG fields. It identifies primary source rocks for gas and condensate resources in the region.

Use Cases

• Model petroleum system charge history based on mapped Jurassic source rock distribution.
• Identify potential hydrocarbon plays based on the interpreted depositional environments of fluvial-deltaic and rift systems.
• Correlate geochemical fluid signatures to specific source rock intervals mentioned in the study.
• Guide exploration in underexplored areas of the basin using the integrated stratigraphic framework.

Strengths

• Integrates multiple geological disciplines: sequence stratigraphy, palaeogeography, and geochemistry.
• Focuses on a basin with considerable gas and condensate resources, including major developed fields.
• Provides a spatial and temporal mapping of source rocks from the Jurassic to earliest Cretaceous.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
