Jurassic Sediment Architecture in Browse Basin for Petroleum Systems Analysis

Browse Basin, offshore Australia, hosts major gas and condensate resources like the Ichthys and Prelude fields. A multi-disciplinary study by Geoscience Australia integrates sequence stratigraphy, palaeogeography, and geochemistry to map Jurassic to earliest Cretaceous source rock distribution. This work aims to clarify the source rock contribution and charge history for known and underexplored hydrocarbon accumulations.

Use Cases

• Model petroleum system charge history based on mapped source rock distribution.
• Identify potential exploration targets based on the spatial and temporal mapping of organic-rich source rocks.
• Correlate geochemical fluid compositions to specific source rock intervals described in the study.
• Analyze depositional environment evolution from fluvial-deltaic to rift systems based on the described supersequences.

Strengths

• Study integrates multiple geological disciplines: sequence stratigraphy, palaeogeography, and geochemistry.
• Focuses on a basin with known, significant hydrocarbon resources, including the Ichthys and Prelude fields.
• Explicitly maps source rocks for specific geological intervals (J10–J20, J30–K10).

Limitations

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