Gage Sandstone CO2 Storage Potential: Seismic Facies and Well Log Analysis

A National Carbon Infrastructure Plan study assesses the CO2 storage suitability of the Gage Sandstone in the Vlaming Sub-basin. The analysis integrates 2D seismic interpretation, well log data from 8 wells, and biostratigraphic reviews to characterize the submarine fan reservoir. The dataset was published by Geoscience Australia and last updated in April 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 submarine fan units.
• Assess reservoir-seal pair integrity for the Gage Sandstone and overlying South Perth Shale.
• Analyze the thickness distribution of the Gage Lowstand Systems Tract, which reaches up to 360 meters.

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.
• Spatial extent of the study area 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.
• Primary data files are in PDF, DOCX, and HTML formats, which may require extraction for computational analysis.
