CO2 Storage Assessment for Offshore South Perth Basin

Geological data assesses the CO2 storage potential of the Vlaming Sub-basin offshore Western Australia. The study integrates seismic, well, and marine datasets to model a laterally extensive reservoir unit covering over 1,500 km2. The assessment was conducted by Geoscience Australia under the National CO2 Infrastructure Plan, with data last updated in April 2026.

Use Cases

• Model CO2 plume migration using interpreted seismic horizons and reservoir depth data between 1400 and 2000 m.
• Assess seal integrity risks for the South Perth Shale regional seal using analyzed seal property data.
• Estimate total storage capacity up to 1 GT of CO2 for the Gage Sandstone reservoir unit.
• Map reservoir thickness distribution (100-300 m) across the 1,500 km2 area for injection site selection.

Strengths

• Focuses on a laterally extensive reservoir unit covering over 1,500 km2.
• Integrates multiple data types including seismic, well, and marine datasets.
• Provides a specific estimated storage capacity of up to 1 GT of CO2.

Limitations

• Specific row counts, column names, and sample data are unavailable.
• Geographic scope is limited to a single sub-basin (Vlaming Sub-basin).
• The dataset is presented in HTML format, which may complicate direct machine analysis.
