Gage Sandstone CO2 Storage Potential in the Vlaming Sub-basin

The Vlaming Sub-basin offshore Western Australia is assessed for its suitability for CO2 storage. This study characterizes the Early Cretaceous Gage Sandstone reservoir, integrating 2D seismic interpretation, well log analysis, and biostratigraphic data from 8 wells. The analysis was conducted by the Australian Ocean Data Network and last updated in June 2026.

Use Cases

• Model CO2 storage capacity based on reservoir properties like 23-30% porosity and 200-1800 mD permeability.
• Map paleogeographic sediment transport directions based on seismic facies interpretations of the submarine fan system.
• Assess reservoir depth suitability for supercritical CO2 injection based on the 1000-3000 m below seafloor range.
• Correlate stratigraphic units using the G. mutabilis dinoflagellate zone as a biostratigraphic marker.

Strengths

• Reservoir properties are quantified with specific ranges: 23-30% porosity and 200-1800 mD permeability.
• Analysis integrates multiple data sources: 2D seismic interpretation, well logs from 8 wells, and biostratigraphic data.
• Spatial extent of the study area is defined as approximately 23,000 km² in the Vlaming Sub-basin.
• Reservoir depth is specified as 1000-3000 m below seafloor, suitable for supercritical CO2.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data files are in document formats (DOCX, PDF, HTML), which may require extraction of underlying data.
