CO2 Storage Prospectivity of the Offshore Vlaming Sub-basin

Geoscience Australia's evaluation of the Gage Sandstone and South Perth Shale for long-term CO2 storage. The study identifies widespread fault reactivation and seismic anomalies potentially indicating hydrocarbon seepage. It highlights spatial variability in seal quality and fault reactivation history for petroleum exploration and CO2 storage assessments.

Use Cases

• Evaluate containment risk for CO2 storage based on identified seismic anomalies.
• Assess seal quality variability for geological storage assessments.
• Analyze fault reactivation history for petroleum exploration and CO2 storage.
• Correlate seismic anomalies with reactivated faults to understand subsurface integrity.

Strengths

• Study conducted by Geoscience Australia as part of the National CO2 Infrastructure Plan.
• Analysis includes seismic data identifying widespread fault reactivation and seismic anomalies.
• Focuses on two specific geological formations: the Gage Sandstone and the overlying South Perth Shale.

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 offshore Vlaming Sub-basin.
