Browse Basin Offshore Assessment for Hydrocarbon 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 analysis over a five-year program, integrating data from airborne magnetic surveys, marine surveys, and geochemical samples. The research provides models for depositional environments, petroleum systems, and identifies prospective CO2 storage sites with reduced conflict for hydrocarbon exploration.

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 system models.
• Evaluate spatial distribution of reservoir, seal, and source rock sections based on revised biostratigraphic data.
• Plan offshore resource development by analyzing areas of potential conflict between CO2 storage and hydrocarbon exploration.

Strengths

• Analysis integrates data from multiple pre-competitive sources, including an airborne magnetic survey and two marine surveys.
• Research is based on an integrated sequence stratigraphic analysis of 60 wells and extensive 2D/3D seismic reflection data.
• Outputs include concrete models and maps for environments of deposition, 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 data_gov_au, focusing solely on the Browse Basin.
