A geological case study assesses the CO2 storage potential of the Early Cretaceous Gage Sandstone in the offshore Vlaming Sub-basin, Western Australia. The analysis integrates 2D seismic interpretation, well log data from 8 wells, and biostratigraphic review to characterize the reservoir. It was published by the Australian Ocean Data Network as part of a National Carbon Infrastructure Plan study.
Use Cases
- Model CO2 storage capacity based on reservoir porosity (23-30%) and permeability (200-1800 mD) data.
- Map subsurface geology for CCS site selection using seismic facies and paleogeographic reconstructions.
- Assess reservoir-seal pair integrity for long-term storage based on the Gage Sandstone and overlying South Perth Shale analysis.
- Analyze sediment transport and fan system evolution from interpreted paleogeographic maps and well intersections.
Strengths
- Specific reservoir property ranges are provided, including porosity (23-30%) and permeability (200-1800 mD).
- Analysis integrates multiple data types: 2D seismic interpretation, well log analysis from 8 wells, and biostratigraphic data.
- The study area is precisely defined as the Vlaming Sub-basin, covering approximately 23,000 km2 with up to 14 km of sediments.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last updated metadata indicates a future date (2026-06-27).
