South Perth Shale Supersequence Palaeogeographic Maps for CO2 Storage Assessment

Geoscience Australia mapped the mudstone facies distribution within the South Perth Shale Supersequence to assess CO2 containment potential. The project, part of the 2011 National CO2 Infrastructure Plan, found sealing capacity varies considerably across the Vlaming Sub-basin. Analysis of the spatial distribution and thickness of this effective seal informs the basin's prospectivity for long-term CO2 storage.

Use Cases

• Assess regional CO2 storage containment potential based on mapped mudstone facies distribution.
• Model CO2 column height capacity using seal thickness and property analysis.
• Evaluate geological risk for carbon capture and storage projects based on variable seal quality.
• Apply sequence-stratigraphic approaches to predict seal rock distribution in other deltaic basins.

Strengths

• Based on a three-year project initiated by Geoscience Australia in 2011.
• Includes analysis of a thick (1900 m) deltaic succession with highly variable lithologies.
• Applies a sequence-stratigraphic approach to map facies distribution across the basin.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified despite the listed 2026 update date.
