Browse Basin Offshore Petroleum Prospectivity and CO2 Storage Assessment

Geoscience Australia conducted a multi-purpose basin analysis under the National CO2 Infrastructure Plan and National Low Emissions Coal Initiative. The assessment integrated pre-competitive data from airborne magnetic surveys, marine surveys, and geochemical analysis to evaluate both CO2 storage potential and hydrocarbon prospectivity. The research 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.
• Assess hydrocarbon exploration opportunities using updated petroleum systems and play fairway models.
• Evaluate potential resource conflicts between CO2 storage and hydrocarbon resources based on spatial distribution maps.
• Model depositional environments and facies variations for reservoir and seal characterization.

Strengths

• Analysis is based on sequence stratigraphic data from 60 wells.
• Integrates data from multiple survey types including airborne magnetic and two marine surveys.
• Project was conducted under a five-year national program (NCIP/NLECI).

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 data_gov_au, focusing solely on the Browse Basin.
