Gage Sandstone CO2 Storage Potential in the Vlaming Sub-basin

A National Carbon Infrastructure Plan study assesses the CO2 storage suitability of the Gage Sandstone in the Vlaming Sub-basin, offshore Western Australia. The dataset, from the Australian Ocean Data Network, integrates 2D seismic interpretation, well log analysis, and biostratigraphic data to characterize the reservoir. It was last updated on 2026-04-10.

Use Cases

• Model CO2 injection and plume migration based on reservoir properties like 23-30% porosity and 200-1800 mD permeability
• Assess reservoir-seal pair integrity for long-term storage based on the Gage Sandstone and overlying South Perth Shale
• Reconstruct paleogeography and sediment transport directions based on seismic facies mapping of the submarine fan system
• Evaluate storage capacity and site suitability based on reservoir depth (1000-3000 m below seafloor) and thickness (up to 360 m)

Strengths

• Reservoir properties are quantified with specific ranges: porosity 23-30% and permeability 200-1800 mD
• Analysis is based on integration of multiple data types: 2D seismic, well logs from 8 wells, and biostratigraphic data
• Study area is clearly defined as the Vlaming Sub-basin, covering approximately 23,000 km2

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the specific offshore basin study
