Browse Basin Offshore Hydrocarbon and CO2 Storage Assessment

Geoscience Australia's five-year program integrated data from 60 wells, airborne magnetic surveys, and marine seismic data to assess the Browse Basin. The analysis provides models for CO2 storage sites and hydrocarbon prospectivity to manage potential resource conflicts. This pre-competitive project was conducted under the National CO2 Infrastructure Plan.

Use Cases

• Identify prospective CO2 storage sites in Cretaceous succession layers using integrated sequence stratigraphic analysis.
• Map hydrocarbon play fairways and petroleum systems from models derived from 2D and 3D seismic reflection data.
• Analyze spatial distribution of reservoir, seal, and source rock sections using revised biostratigraphic data.
• Assess basin-scale storage potential by integrating pre-competitive data from airborne magnetic and marine surveys.

Strengths

• Integrated analysis of data from 60 wells for sequence stratigraphy.
• Utilizes an extensive set of industry and government 2D and 3D seismic reflection data.
• Project outputs include models and maps for environments of deposition and petroleum systems.

Limitations

• Primary data formats are PDF and HTML, limiting direct machine-readability for analysis.
• Specific sample data, row counts, and file sizes are unavailable for review.
• The dataset's temporal coverage and specific geographic coordinates are not explicitly defined.
