Petroleum and CO2 Storage Assessment for the Offshore Browse Basin, Australia

Geoscience Australia undertook a five-year multi-purpose basin analysis under the National CO2 Infrastructure Plan. The assessment integrated data from an airborne magnetic survey, two marine surveys, and geochemical analysis of oils, gases, and rocks, alongside 60 wells and extensive 2D/3D seismic data. Outputs include models and maps of depositional environments, petroleum systems, and play fairways to identify prospective CO2 storage sites with minimal conflict to hydrocarbon exploration.

Use Cases

• Identify prospective CO2 storage sites based on integrated sequence stratigraphic analysis and seismic data.
• Assess hydrocarbon prospectivity and play fairways based on updated tectonostratigraphic framework and biostratigraphic data.
• Model environments of deposition and petroleum systems based on the integration of pre-competitive geophysical and geochemical data.
• Evaluate potential resource conflicts between CO2 storage and hydrocarbon exploration based on spatial distribution maps of reservoir and seal sections.

Strengths

• Analysis integrates data from multiple surveys, including an airborne magnetic survey and two marine surveys.
• Research is based on an integrated sequence stratigraphic analysis of 60 wells and extensive 2D/3D seismic data.
• Project outputs include updated basin models and spatial distribution maps for reservoir, seal, and source rock.

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 and source bias inherent to the specific industry-provided repository.
