CO2 Storage Potential in the Offshore Vlaming Sub-Basin, Australia

Geoscience Australia conducted a study between 2011 and 2014 to assess CO2 storage potential in the offshore Vlaming Sub-basin. The study provides new pre-competitive data on reservoir-seal pairs, storage capacity, and environmental baselines. It confirmed the suitability of the Gage Sandstone reservoir for long-term CO2 storage.

Use Cases

• Model CO2 storage capacity based on reservoir characteristics and seal integrity assessments.
• Identify suitable storage sites based on the delineation of the Gage Sandstone reservoir.
• Assess environmental risks for future CO2 storage projects using the provided environmental baseline data.
• Characterize geological heterogeneity for reservoir simulation based on the study's detailed assessment.

Strengths

• Study conducted by a national geological survey (Geoscience Australia) as part of the National CO2 Infrastructure Plan.
• Focuses on a basin covering approximately 23,000 km2 with up to 14 km of sediments, located near industrial CO2 sources.
• Addresses specific critical issues like reservoir heterogeneity, seal quality, and practical storage capacity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF, ZIP, DOCX, and HTML formats, which may require extraction and conversion for analysis.
