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

An assessment for the Australian Government's National CO2 Infrastructure Plan, conducted by Geoscience Australia, focusing on the offshore Vlaming Sub-basin in the South Perth Basin. The study integrates seismic, well, and marine datasets to evaluate the Gage Sandstone reservoir and South Perth Shale seal. It estimates a storage capacity of up to 1 gigatonne of CO2.

Use Cases

• Model CO2 plume migration based on the described reservoir geometry and properties.
• Assess seal integrity risks for long-term storage based on the analysis of the South Perth Shale.
• Estimate regional storage capacity based on the reservoir's lateral extent and thickness.
• Plan injection strategies based on the reservoir depth and supercritical CO2 suitability.

Strengths

• Estimates a substantial storage capacity of up to 1 gigatonne of CO2.
• Describes a laterally extensive reservoir unit covering over 1,500 square kilometers.
• Integrates multiple data types including seismic, well, and marine datasets.

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.
