CO2 Storage Assessment for the Offshore Vlaming Sub-Basin

A 2011-2014 study by Geoscience Australia assessed the CO2 storage potential of the offshore Vlaming Sub-basin. The work provided new pre-competitive data on reservoir-seal pairs, storage capacity, and environmental baselines for an area of approximately 23,000 km2. It confirmed the suitability of the Gage Sandstone reservoir for long-term CO2 storage.

Use Cases

• Estimate practical CO2 storage capacity using reservoir characterisation and seal integrity data.
• Identify suitable storage sites by analyzing delineation data for the Gage Sandstone reservoir and South Perth Shale seal.
• Assess environmental impact by referencing the provided environmental baseline and potential issues of concern.
• Model reservoir heterogeneity for the Gage Sandstone to inform injection strategy simulations.

Strengths

• Study conducted over a 3-year period from 2011 to 2014.
• Focuses on a defined geographical area of approximately 23,000 km2 with up to 14 km of sediments.
• Addresses specific critical issues including seal quality, storage capacity, and environmental baseline.

Limitations

• Specific row counts, column names, and sample data are unavailable.
• Data is contained in document formats (PDF, DOCX) requiring manual extraction for analysis.
• Temporal coverage of the underlying geological data is not specified.
