CO2 Storage Assessment for the Offshore Vlaming Sub-basin, Australia

Up to 1 gigatonne of CO2 can be stored in the Early Cretaceous Gage Sandstone reservoir of the Vlaming Sub-basin. Geoscience Australia produced this assessment by interpreting and integrating seismic, well, and marine datasets to evaluate reservoir properties and seal integrity risks. The study, part of the National CO2 Infrastructure Plan, was last updated in April 2026.

Use Cases

• Model CO2 plume migration based on described reservoir geometry and seal properties.
• Assess long-term storage security based on the analysis of seal integrity risks.
• Estimate regional storage capacity based on the mapped lateral extent of the Gage Sandstone.
• Plan injection strategies based on reservoir depth and thickness parameters.

Strengths

• Assesses a reservoir with a mapped lateral extent over 1,500 km².
• Integrates multiple data types including seismic, well, and marine datasets.
• Provides a specific storage capacity estimate of up to 1 gigatonne of CO2.

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, focusing on a single Australian basin.
