CO2 Storage Prospectivity in the Offshore Vlaming Sub-basin

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 seal variability and fault history for both petroleum exploration and CO2 storage.

Use Cases

• Assessing geological containment risk for CO2 storage based on identified fault reactivation.
• Evaluating seal quality for subsurface storage projects based on seismic anomaly analysis.
• Correlating seismic anomalies with reactivated faults to understand subsurface fluid migration pathways.

Strengths

• Assessment conducted by Geoscience Australia as part of a national infrastructure plan.
• 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.
• Description metadata is limited; actual data quality requires manual inspection after download.
