CO2 Storage Potential Assessment for the Browse Basin, Offshore Australia

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 assess storage plays, focusing on the Cretaceous succession to minimize conflict with hydrocarbon resources. Results indicate the Lower Cretaceous basin margin and Upper Cretaceous confined submarine fan plays are more prospective for CO2 storage.

Use Cases

• Map CO2 storage play fairways based on the revised tectonostratigraphic framework and play fairway mapping approach.
• Assess risk for geological CO2 storage based on common risk element maps for reservoir depth, fault distribution, and hydrocarbon conflicts.
• Model basin structure and sequence stratigraphy using updated interpretations of deep faults and Cretaceous sequences.
• Identify areas suitable for CO2 storage with reduced conflict based on the analysis of existing and undiscovered hydrocarbon accumulations.

Strengths

• Assessment integrates data from over 60 wells, regional 2D and 3D seismic reflection surveys, and potential field data.
• Study provides a focused analysis of the Cretaceous succession to reduce conflict with hydrocarbon exploration.
• Results include common risk element maps for each supersequence, enabling high-grading of potential storage 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 the specific offshore basin study area.
