Geoscience Australia assessed the Vlaming Sub-basin for CO2 storage as part of the National CO2 Infrastructure Plan. The primary reservoir, the Early Cretaceous Gage Sandstone, covers over 1,500 km2 and lies at depths between 1400 and 2000 m below the seafloor, with an estimated capacity of up to 1 GT of CO2. This study integrates seismic, well, and marine datasets to evaluate reservoir properties and seal integrity risks.
Use Cases
- Model CO2 plume migration based on reservoir geometry and thickness (100-300 m)
- Assess storage site suitability based on reservoir depth (1400-2000 m) and seal properties
- Estimate regional storage capacity based on the laterally extensive (over 1,500 km2) Gage Sandstone unit
- Evaluate seal integrity risks for long-term containment based on the overlying South Perth Shale
Strengths
- Assessment focuses on a specific, laterally extensive reservoir unit (over 1,500 km2)
- Includes detailed analysis of reservoir depth (1400-2000 m) and thickness (100-300 m)
- Integrates multiple data types (seismic, well, marine) for a comprehensive evaluation
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
