Browse Basin Offshore Assessment for Hydrocarbon Prospectivity and CO2 Storage Potential

Australia's offshore Browse Basin on the North West Shelf is the subject of this multi-purpose geological assessment. Geoscience Australia conducted the research over a five-year program, integrating data from airborne magnetic surveys, marine surveys, and geochemical analyses. The outputs include updated tectonostratigraphic models, depositional environment maps, 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 prospectivity and play fairways using updated tectonostratigraphic frameworks and petroleum systems models.
• Evaluate potential resource conflicts between CO2 storage and hydrocarbon exploration based on spatial distribution maps of reservoir and seal sections.

Strengths

• Analysis is based on an integrated sequence stratigraphic analysis of 60 wells.
• Incorporates an extensive set of industry and government 2D and 3D seismic reflection data.
• Integrates pre-competitive data from multiple survey types, including airborne magnetic and two marine surveys.

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.
