Browse Basin CO2 Storage Potential Assessment for Australia's National Infrastructure Plan

Geoscience Australia assessed the geological CO2 storage potential of the Browse Basin offshore northwest Australia between 2013 and 2015. The study integrated data from over 60 wells, regional 2D/3D seismic surveys, and potential field data to identify prospective storage plays. Results indicate Lower Cretaceous basin margin plays and an Upper Cretaceous submarine fan play are potentially more prospective for CO2 storage.

Use Cases

• Identify prospective CO2 storage sites based on the play fairway mapping approach described.
• Assess risk of conflict with hydrocarbon exploration based on the analysis of reservoir depth, fault distribution, and resource conflicts.
• Update regional tectonic structure models using the revised tectonostratigraphic framework for the Cretaceous succession.
• Generate common risk element maps for CO2 storage by overlaying constraints like reservoir-seal pairs and fault distribution.

Strengths

• Integrated analysis using data from over 60 wells and regional 2D/3D seismic reflection surveys.
• Study focused on a specific geological interval (Cretaceous succession) to reduce conflict risk with hydrocarbon resources.
• Assessment produced common risk element maps for each supersequence to high-grade potential storage fairways.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last metadata update was 2026-06-23 03:16:06.414145.
