Browse Basin Petroleum and CO2 Storage Assessment Models

Geoscience Australia conducted a multi-purpose basin analysis for the offshore Browse Basin. The project integrated data from 60 wells, airborne magnetic surveys, marine surveys, and extensive 2D/3D seismic data. This pre-competitive research, updated in April 2026, assessed CO2 storage potential and hydrocarbon prospectivity.

Use Cases

• Identify prospective CO2 storage sites using models of depositional environments and seal rock distribution to avoid conflict with hydrocarbon resources.
• Assess hydrocarbon play fairways by analyzing integrated sequence stratigraphy from 60 wells and seismic reflection data.
• Model petroleum systems using outputs from geochemical analysis of oils, gases, and rocks provided by industry.
• Update the basin's tectonostratigraphic framework with revised biostratigraphic data to understand spatial distribution of reservoir and source rock sections.
• Evaluate basin-scale storage potential by integrating pre-competitive data from airborne magnetic and marine surveys.

Strengths

• Integrated analysis of 60 wells for sequence stratigraphy.
• Utilized extensive industry and government 2D and 3D seismic reflection data.
• Multi-year project under the National CO2 Infrastructure Plan, with data current as of April 2026.

Limitations

• Primary outputs are interpretive models and maps (PDF/HTML), not raw structured data tables.
• Sample data and specific row/column counts for underlying datasets are unavailable.
• Geographic scope is limited to the single Browse Basin depocentre.
