Browse Basin Offshore Data for CO2 Storage and Petroleum Prospectivity Assessment

The Browse Basin is a northeast-trending Paleozoic to Cenozoic depocentre offshore Australia's North West Shelf. Geoscience Australia undertook this multi-purpose basin analysis under the National CO2 Infrastructure Plan, integrating data from airborne magnetic surveys, marine surveys, and geochemical analysis to assess CO2 storage potential and hydrocarbon prospectivity. The project updated the basin's tectonostratigraphic framework using sequence stratigraphic analysis of 60 wells and extensive 2D/3D seismic data.

Use Cases

• Identify prospective CO2 storage sites based on integrated sequence stratigraphic analysis and seismic reflection data.
• Assess hydrocarbon prospectivity and play fairways using models of depositional environments and petroleum systems.
• Evaluate potential resource conflicts between CO2 storage and hydrocarbon exploration using spatial distribution maps.
• Improve future CCS technology deployment by analyzing storage potential in suitable reservoirs.

Strengths

• Analysis integrates multiple pre-competitive data sources, including airborne magnetic surveys, two marine surveys, and geochemical analysis.
• The basin's tectonostratigraphic framework was updated using sequence stratigraphic analysis of 60 wells.
• Research utilized an extensive set of industry and government 2D and 3D seismic reflection data.

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.
