Vlaming Sub-Basin CO2 Storage Study Results from the NCIP Program

Between 2011 and 2014, Geoscience Australia conducted a study of the offshore Vlaming Sub-basin to assess its potential for carbon dioxide storage. The study focused on characterizing the Gage Sandstone reservoir and South Perth Shale seal, providing a more accurate estimate of storage capacity and environmental baselines. It confirmed the suitability of the reservoir for long-term CO2 storage while highlighting considerations for containment and environmental impact.

Use Cases

• Model subsurface CO2 storage capacity based on reservoir and seal characterization.
• Assess geological containment risks for carbon storage projects based on seal integrity analysis.
• Establish environmental baselines for future monitoring of offshore CO2 injection sites.
• Identify prospective storage sites within the Vlaming Sub-basin based on the delineated suitable areas.

Strengths

• Study conducted by the national geological survey, Geoscience Australia.
• Focuses on a basin covering approximately 23,000 km2 with up to 14 km of sediments.
• Addresses specific gaps in prior assessments, including reservoir heterogeneity and seal quality.

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/temporal bias inherent to data_gov_au.
