CO2 Storage Assessment for the Offshore South Perth Basin, Australia

Geoscience Australia assessed the Vlaming Sub-basin for storing up to 1 gigaton of CO2 in the Gage Sandstone reservoir. The study integrates seismic, well, and marine data to model storage capacity and seal integrity risks. This work supports the Australian Government's National CO2 Infrastructure Plan.

Use Cases

• Model CO2 plume migration based on the described reservoir geometry and seal properties.
• Assess regional storage capacity based on the estimated 1 GT potential of the Gage Sandstone.
• Evaluate seal integrity risks for long-term containment using integrated seismic and well data.
• Plan injection strategies based on reservoir depth (1400-2000m) suitable for supercritical CO2.

Strengths

• Assesses a laterally extensive reservoir unit covering over 1,500 km2.
• Integrates multiple data types including seismic, well, and marine datasets.
• Provides a specific storage capacity estimate of up to 1 gigaton of CO2.
• Focuses on a basin in close proximity to industrial polluters, highlighting practical relevance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific offshore basin study.
