Integrated Modelling of CO₂ Storage in Multi-Operator Basins

A 30-year simulation study of CO₂ storage in the Barrow–Dampier sub-basin, quantifying regional pressure effects on capacity and injectivity. The dataset, from Geoscience Australia, models a 4,310 km² domain with five candidate storage formations and six injectors per formation. Results demonstrate the impact of integrated regional modelling versus isolated site assessments.

Use Cases

• Assess dynamic storage capacity based on regional pressure communication.
• Model inter-project interference for multiple CO₂ injection sites.
• Evaluate the impact of aquifer support on injectivity based on Carter-Tracy r-ratios.
• Design monitoring footprints for CO₂ storage operations.
• Inform regulatory frameworks for multi-operator basin management.

Strengths

• Models a 4,310 km² domain with five candidate storage formations.
• Simulates 18 cases with varied boundary conditions and aquifer strengths.
• Quantifies a significant capacity reduction from ~924 Mt to 514 Mt under closed boundaries.

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 data_gov_au.
