An Integrated Study of the CO2 Storage Potential in the Offshore Vlaming Sub-Basin

Geoscience Australia conducted a study between 2011 and 2014 to assess CO2 storage in the offshore Vlaming Sub-basin, an area of approximately 23,000 km2 located about 30 km west of Perth. The work focused on characterizing reservoir heterogeneity, seal quality, and environmental baselines for the prospective Gage Sandstone reservoir. The study confirmed the reservoir's suitability for long-term CO2 storage and provided more accurate site delineation.

Use Cases

• Model CO2 storage capacity based on the detailed assessment of the Gage Sandstone reservoir and South Perth Shale seal.
• Assess geological containment risks using the study's findings on reservoir heterogeneity and seal integrity.
• Plan environmental monitoring baselines for future projects using the provided environmental baseline data.
• Evaluate regional carbon storage potential by integrating the study's more accurate storage capacity estimates.

Strengths

• Study covers a specific, large geographical area of approximately 23,000 km2.
• Research addresses previously unexplored critical issues like seal quality and environmental baselines.
• Provides a more accurate delineation of suitable storage sites based on the integrated study.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
