CO2 Storage Prospectivity Assessment for the Offshore Vlaming Sub-basin

The offshore Vlaming Sub-basin in Australia is the focus of this assessment for long-term CO2 storage. Geoscience Australia evaluated the Gage Sandstone and South Perth Shale formations, identifying widespread fault reactivation and seismic anomalies. The study highlights spatial variability in seal quality and fault reactivation history for both petroleum exploration and CO2 storage.

Use Cases

• Assessing containment risk for CO2 storage based on identified fault reactivation.
• Evaluating seal quality for geological formations based on seismic data analysis.
• Correlating seismic anomalies with fault structures for hydrocarbon seepage studies.
• Supporting petroleum exploration assessments with data on spatial seal variability.

Strengths

• Assessment conducted by Geoscience Australia as part of the National CO2 Infrastructure Plan (NCIP).
• Analysis includes two specific geological formations: the Gage Sandstone and the overlying South Perth Shale.
• Identifies specific geological features: widespread fault reactivation and seismic anomalies.

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 data_gov_au.
