Vlaming Sub-Basin Seabed Survey for CO2 Storage Assessment, 2012

Geoscience Australia conducted a seabed characterisation survey in March and April 2012 to support CO2 storage potential assessment in the Vlaming Sub-basin, Western Australia. The survey collected 653 km² of multibeam and backscatter data, 6.65 km² of side-scan sonar imagery, and 89 seabed grab samples from 43 stations. Data acquisition focused on two areas above the South Perth Shale seal and the Gage Sandstone reservoir.

Use Cases

• Modeling potential CO2 reservoir seal integrity based on seabed and sub-bottom profile data.
• Analyzing seabed geomorphology and structural geology correlations based on described fault-like structures and lineaments.
• Characterizing rhodolith bed habitats and their relationship to underlying geology based on survey descriptions of Area 2.
• Mapping seafloor features like mounds and ridges based on multibeam and side-scan sonar data.

Strengths

• Survey collected 653 km² of multibeam and backscatter data.
• Includes 89 seabed grab samples from 43 stations.
• Acquired 6.65 km² of side-scan sonar imagery and concurrent chirper sub-bottom profiles.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The relationship between seabed features and underlying geology is described as uncertain, requiring further work.
