Browse Basin Jurassic Sediment Architecture and Petroleum Source Rock Analysis

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, hosted by the Australian Ocean Data Network, aims to better understand source rock contributions to hydrocarbon accumulations like the Ichthys and Prelude fields. The dataset was last updated on 2026-04-10.

Use Cases

• Model petroleum system charge history based on mapped source rock distribution.
• Identify potential exploration targets in underexplored areas based on depositional architecture.
• Correlate geochemical fluid compositions with specific source rock intervals mentioned in the description.
• Analyze the impact of pre-breakup extension and rift phases on source rock deposition.

Strengths

• Focuses on a basin with considerable gas and condensate resources, including major fields like Ichthys and Prelude.
• Integrates multiple geological disciplines: sequence stratigraphy, palaeogeography, and geochemistry.
• Explicitly maps source rocks for the Lower–Middle Jurassic (J10–J20) and Late Jurassic–earliest Cretaceous (J30–K10) intervals.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data format is PDF, which may require extraction for computational analysis.
