A National Carbon Infrastructure Plan study assesses the CO2 storage suitability of the Vlaming Sub-basin offshore Western Australia. The analysis integrates 2D seismic interpretation, well log analysis, and biostratigraphic data from 8 wells to characterize the Early Cretaceous Gage Sandstone reservoir. The reservoir has porosities of 23-30% and permeabilities of 200-1800 mD, lying between 1000 and 3000 meters below the seafloor.
Use Cases
- Model CO2 injection capacity based on reservoir porosity and permeability ranges
- Map submarine fan system evolution based on paleogeographic reconstructions
- Assess regional seal integrity for CO2 containment based on the South Perth Shale overlay
- Characterize reservoir geometry based on seismic facies mapping and well log interpretations
Strengths
- Reservoir properties are quantified with specific porosity (23-30%) and permeability (200-1800 mD) ranges
- Analysis is based on data from 8 wells and integrates seismic, well log, and biostratigraphic methods
- Geographic scope is defined as the Vlaming Sub-basin, 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 data_gov_au
