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

Geoscience Australia's assessment of the Vlaming Sub-basin for CO2 storage, part of the National CO2 Infrastructure Plan. The study integrates seismic, well, and marine datasets to analyze the Gage Sandstone reservoir and South Perth Shale seal. It estimates a storage capacity of up to 1 gigatonne of CO2 in the laterally extensive reservoir unit.

Use Cases

• Model CO2 plume migration based on described reservoir geometry and seal properties.
• Assess storage site integrity risks based on the comprehensive evaluation of seal integrity mentioned.
• Estimate regional storage capacity based on the reservoir's lateral extent and thickness.
• Plan injection strategies based on reservoir depth and supercritical CO2 suitability criteria.

Strengths

• Estimates a concrete storage capacity of up to 1 gigatonne of CO2.
• Describes a reservoir with specific dimensions: over 1,500 km2 in area and 100-300 m thick.
• Based on integration of multiple data types: 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 is presented in HTML format, which may require extraction for computational analysis.
