Gage Sandstone CO2 Storage Potential in the Vlaming Sub-basin

A National Carbon Infrastructure Plan study assesses the 23,000 km2 Vlaming Sub-basin for CO2 storage. The analysis, conducted by Geoscience Australia, integrates 2D seismic interpretation and well log data from 8 wells to characterize the Early Cretaceous Gage Sandstone reservoir, which has porosities of 23-30% and permeabilities of 200-1800 mD.

Use Cases

• Model CO2 storage capacity based on reservoir porosity and permeability data
• Map subsurface reservoir geometry based on seismic facies interpretations
• Analyze sediment transport and depositional environments from paleogeographic reconstructions
• Assess seal integrity for CO2 containment based on the overlying South Perth Shale formation

Strengths

• Reservoir properties are quantified with specific porosity (23-30%) and permeability (200-1800 mD) ranges
• Spatial extent of the study area is defined as approximately 23,000 km2
• Analysis integrates data from 8 wells and 2D seismic interpretation

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data freshness should be verified despite a future last-updated date
