Browse Basin CO2 Storage Potential Assessment with Hydrocarbon Conflict Analysis

Geoscience Australia conducted a regional assessment of geological CO2 storage potential in the Browse Basin, offshore northwest Australia, between 2013 and 2015. The study used data from over 60 wells, regional 2D and 3D seismic surveys, and potential field data to assess storage plays in the Cretaceous succession. Results indicate the Lower Cretaceous basin margin and Upper Cretaceous confined submarine fan plays are more prospective for CO2 storage.

Use Cases

• Modeling regional CO2 storage capacity based on the integrated assessment of reservoir, seal, and fault distribution.
• Identifying areas with reduced resource conflict for CO2 storage based on the analysis of hydrocarbon prospectivity.
• Analyzing basin structure and sequence stratigraphy for CCS planning using the updated regional-scale tectonic framework.
• Risk assessment for geological storage using the common risk element maps produced for each supersequence.

Strengths

• Assessment integrates data from over 60 wells, regional 2D and 3D seismic reflection surveys, and potential field data.
• Study focuses on the Cretaceous succession to reduce conflict between CO2 storage and hydrocarbon exploration.
• Analysis includes specific constraints like reservoir depth range, fault distribution, and hydrocarbon resource conflicts.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic bias inherent to the single-basin study area.
