CO2 Storage Containment Risk Assessment for Offshore Vlaming Sub-basin

Geoscience Australia's evaluation identifies widespread fault reactivation and seismic anomalies potentially indicating hydrocarbon seepage within the Gage Sandstone and South Perth Shale. This assessment forms part of the National CO2 Infrastructure Plan to evaluate long-term CO2 storage potential. The data was published by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Assess spatial variability in seal quality using seismic anomaly and fault reactivation data.
• Evaluate containment risk for CO2 storage by correlating seismic anomalies with reactivated faults.
• Model long-term CO2 storage potential in the Gage Sandstone based on fault and seal assessments.

Strengths

• Analysis based on seismic data identifying specific geological features.
• Assessment conducted as part of a national infrastructure plan (NCIP).

Limitations

• Specific data volume (row count, column count) is unknown.
• Underlying raw seismic datasets are not directly provided.
