Browse Basin Offshore Petroleum and CO2 Storage Assessment

A multi-year pre-competitive analysis program by Geoscience Australia assessed hydrocarbon prospectivity and long-term CO2 storage potential in the Browse Basin. The research integrated data from an airborne magnetic survey, two marine surveys, and geochemical analysis of oils, gases, and rocks provided by industry. Outputs include updated tectonostratigraphic models, maps of depositional environments, petroleum systems, and identified prospective CO2 storage sites.

Use Cases

• Identify prospective CO2 storage sites based on integrated sequence stratigraphic analysis of 60 wells and seismic data.
• Assess hydrocarbon play fairways using models and maps of petroleum systems derived from pre-competitive basin analysis.
• Evaluate resource conflicts by locating storage areas least likely to interfere with hydrocarbon exploration, as mentioned in the description.
• Update basin tectonostratigraphic frameworks based on revised biostratigraphic data and analysis of reservoir, seal, and source rock distribution.

Strengths

• Integrated analysis of 60 wells and extensive industry and government 2D/3D seismic reflection data.
• Pre-competitive data derived from an airborne magnetic survey, two marine surveys, and geochemical analysis.
• Project outputs include updated basin models and maps for both hydrocarbon prospectivity and CO2 storage assessment.

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 bias inherent to the specific offshore basin studied.
