Gage Sandstone CO2 Storage Potential in the Vlaming Sub-basin, Offshore Western Australia

A 23,000 km2 offshore basin containing up to 14 km of sediments is assessed for carbon storage. This case study integrates 2D seismic interpretation, well log analysis, and biostratigraphic data to characterize the Early Cretaceous Gage Sandstone reservoir. The reservoir, intersected in 8 wells, exhibits porosities of 23-30% and permeabilities of 200-1800 mD, lying at depths suitable for supercritical CO2 injection.

Use Cases

• Model CO2 storage capacity based on reservoir porosity and permeability ranges mentioned in the description
• Analyze submarine fan system evolution using paleogeographic reconstructions derived from seismic facies mapping
• Assess seal integrity for carbon storage based on the described regional South Perth Shale formation
• Correlate stratigraphic units using the revised G. mutabilis dinoflagellate zone interpretations

Strengths

• Specific reservoir property ranges provided: 23-30% porosity and 200-1800 mD permeability
• Study integrates multiple data types: 2D seismic, well logs from 8 wells, and biostratigraphic data
• Clear geographical scope defined: the Vlaming Sub-basin, approximately 23,000 km2 in area

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data files are in PDF, DOCX, and HTML formats, which may require extraction for computational analysis
