CO2 Storage Potential Assessment of Offshore Vlaming Sub-Basin

Geoscience Australia conducted a study from 2011 to 2014 assessing CO2 storage in the offshore Vlaming Sub-basin, covering approximately 23,000 km2. The research confirmed the suitability of the Gage Sandstone reservoir for long-term storage and provided more accurate site delineation.

Use Cases

• Model CO2 storage capacity in the Gage Sandstone reservoir using updated geological characterizations.
• Assess seal integrity and containment risks for potential storage sites, focusing on the South Perth Shale.
• Establish environmental baselines for the Vlaming Sub-basin to evaluate potential impacts of CO2 storage projects.
• Analyze reservoir heterogeneity data to identify the most prospective locations for CO2 injection.

Strengths

• Study conducted by Geoscience Australia, a national geological survey organization.
• Focuses on a basin covering approximately 23,000 km2 with up to 14 km of sediment thickness.
• Addresses specific critical issues like reservoir heterogeneity, seal quality, and environmental baseline.

Limitations

• Dataset consists of reports (HTML, PDF, DOCX) and archives (ZIP), not structured tabular data for direct computational analysis.
• Primary data collection concluded in 2014, potentially lacking very recent geological or environmental measurements.
• Findings are specific to the Vlaming Sub-basin, limiting direct applicability to other geological regions.
