CO2 Storage Prospectivity of the Offshore Vlaming Sub-basin: Evaluating Containment Risk

Geoscience Australia evaluated the Gage Sandstone and South Perth Shale for long-term CO2 storage as part of the National CO2 Infrastructure Plan. The assessment identified widespread fault reactivation and seismic anomalies potentially indicating hydrocarbon seepage. The study highlights the importance of understanding spatial variability in seal quality and fault reactivation history for both petroleum exploration and CO2 storage.

Use Cases

• Assessing CO2 storage site containment risk based on identified fault reactivation.
• Evaluating seal quality variability for geological storage based on seismic anomaly analysis.
• Correlating seismic anomalies with fault structures for petroleum exploration assessments.

Strengths

• Produced by Geoscience Australia, a national geological survey organization.
• Analysis includes seismic data identifying widespread fault reactivation and anomalies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Vlaming Sub-basin.
