CO2 Storage Prospectivity of 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 the importance of spatial variability in seal quality and fault reactivation history for both petroleum exploration and CO2 storage assessments.

Use Cases

• Assess containment risk for CO2 storage based on identified fault reactivation.
• Evaluate seal quality variability for geological storage sites based on seismic data analysis.
• Correlate seismic anomalies with fault structures for hydrocarbon seepage studies.

Strengths

• Analysis conducted by Geoscience Australia, a national geological survey organization.
• Assessment includes seismic data identifying fault reactivation and potential seepage anomalies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF, DOCX, and HTML formats, which may require extraction for quantitative analysis.
