CO2 Storage Prospectivity and Containment Risk 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 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 for geological storage based on seismic anomaly analysis.
• Correlating seismic anomalies with fault structures for hydrocarbon seepage studies.
• Informing petroleum exploration strategies based on spatial variability in seal properties.

Strengths

• Assessment conducted by Geoscience Australia, a national geological survey.
• Analysis includes seismic data for the offshore Vlaming Sub-basin.
• Study is part of the National CO2 Infrastructure Plan (NCIP).

Limitations

• Data is provided in document formats (PDF, DOCX, HTML); structured tabular or geospatial data may require extraction.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
