Browse Basin CO2 Storage Potential Assessment

Geoscience Australia conducted a regional assessment of geological CO2 storage potential in the Browse Basin, offshore northwest Australia, between 2013 and 2015. The study integrated data from over 60 wells, regional 2D and 3D seismic surveys, and potential field data to evaluate storage plays. It was part of the Australian Government's National CO2 Infrastructure Plan.

Use Cases

• Map CO2 storage play fairways by overlaying constraints like reservoir depth range, fault distribution, and hydrocarbon resource conflicts on revised tectonostratigraphic frameworks.
• Identify areas with reduced conflict for CO2 storage by analyzing the distribution of Jurassic and Lower Cretaceous hydrocarbon accumulations versus Cretaceous succession targets.
• Assess containment risks for potential storage sites using common risk element maps generated for each Cretaceous supersequence.
• Update regional basin structure models for storage assessment using data on deep faults from Permian-Cretaceous rifting and Cenozoic collision events.

Strengths

• Integrated analysis using data from over 60 wells and multiple regional 2D and 3D seismic reflection surveys.
• Assessment covers specific geological intervals (Cretaceous succession) to minimize conflict with hydrocarbon resources.
• Study produced common risk element maps for each supersequence to high-grade storage play fairways.

Limitations

• Primary data formats (PDF, ZIP, DOCX) are not immediately machine-readable for analysis without extraction.
• The study's temporal coverage is fixed (2013-2015), and subsurface data may not reflect recent conditions.
• Specific sample sizes (e.g., exact row counts for well data) and quantitative metrics for storage potential are not provided in the description.
