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 spatial variability in seal quality and fault reactivation 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 fault structures to understand hydrocarbon migration pathways.
• Informing petroleum exploration strategies by analyzing spatial variability in seal properties.

Strengths

• Produced by Geoscience Australia, a national geological survey organization.
• Analysis includes seismic data interpretation for fault reactivation and seal quality.
• Study is part of the structured National CO2 Infrastructure Plan (NCIP).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
