Browse Basin Assessment for CO2 Storage and Hydrocarbon Prospectivity, Offshore Australia

A multi-purpose basin analysis project by Geoscience Australia under the National CO2 Infrastructure Plan and National Low Emissions Coal Initiative. The research integrates 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, models of depositional environments, petroleum systems, and play fairways.

Use Cases

• Identify prospective CO2 storage sites based on integrated sequence stratigraphic analysis of 60 wells and seismic data.
• Model petroleum systems and play fairways for hydrocarbon exploration based on updated tectonostratigraphic frameworks.
• Assess potential resource conflicts between CO2 storage and hydrocarbon resources using spatial distribution models of reservoir, seal, and source rock sections.
• Improve future storage site selection for CCS technology based on the basin's Cretaceous succession analysis.

Strengths

• Analysis integrates data from multiple sources: an airborne magnetic survey, two marine surveys, and geochemical analysis.
• Research is based on an integrated sequence stratigraphic analysis of 60 wells and extensive 2D/3D seismic reflection data.
• Project outputs include updated tectonostratigraphic frameworks and models of depositional environments, 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.
• Data may reflect geographic bias inherent to the specific offshore Browse Basin study area.
