Browse Basin Offshore Assessment for Hydrocarbon and CO2 Storage Potential

Geoscience Australia conducted a multi-purpose basin analysis under the National CO2 Infrastructure Plan and National Low Emissions Coal Initiative. The project integrated pre-competitive data from airborne magnetic surveys, marine surveys, and geochemical analysis to assess CO2 storage potential and hydrocarbon prospectivity in the Browse Basin. Outputs include updated tectonostratigraphic frameworks, sequence stratigraphic analysis of 60 wells, and models of depositional environments, petroleum systems, and play fairways.

Use Cases

• Identify prospective CO2 storage sites based on integrated geological models and maps.
• Assess hydrocarbon exploration opportunities using updated play fairway and petroleum system models.
• Evaluate reservoir, seal, and source rock distributions from revised biostratigraphic and seismic data.
• Analyze basin-scale storage potential to manage resource conflicts between CCS and hydrocarbon development.

Strengths

• Analysis integrates data from multiple sources, including an airborne magnetic survey and two marine surveys.
• Sequence stratigraphic framework is based on 60 wells and extensive 2D and 3D seismic reflection data.
• Project outputs include concrete models and maps for environments of deposition, petroleum systems, and play fairways.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical tasks.
• Data is provided in PDF and HTML formats, which may require extraction for computational analysis.
