CO2 Storage Potential in the Offshore Vlaming Sub-Basin

Geoscience Australia conducted a study between 2011 and 2014 to assess CO2 storage potential in the offshore Vlaming Sub-basin. The basin covers approximately 23,000 km2 west of Perth and contains up to 14 km of sediments. The study focused on characterizing the Gage Sandstone reservoir and South Perth Shale seal, estimating practical storage capacity, and establishing an environmental baseline.

Use Cases

• Model CO2 storage capacity based on reservoir-seal pair assessments mentioned in the description
• Assess geological containment risks based on seal quality and integrity analysis
• Evaluate environmental impact for future projects using the environmental baseline data
• Map potential storage sites based on the delineation of suitable areas

Strengths

• Study conducted by Geoscience Australia as part of the National CO2 Infrastructure Plan (NCIP)
• Focuses on a basin covering approximately 23,000 km2 with up to 14 km of sediments
• Addresses specific scientific issues like reservoir heterogeneity and seal integrity

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
