Jurassic Sediment Architecture in Browse Basin for Petroleum Systems Analysis

Geoscience Australia Data conducted a multi-disciplinary study integrating 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 understand the source rocks' contribution to known hydrocarbon accumulations and charge history.

Use Cases

• Model petroleum system charge history based on mapped source rock distribution.
• Identify potential hydrocarbon plays based on the interpreted depositional environments (e.g., fluvial-deltaic, rift).
• Correlate geochemical fluid compositions to specific source rock intervals mentioned in the description.

Strengths

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

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.
