Australian Sedimentary Basin Formation Water Composition for CO2 Storage Analysis

Over 900 well measurements of formation water composition assess conditions for CO2 solubility trapping in major Australian sedimentary basins. The dataset, compiled by Geoscience Australia, focuses on total dissolved solid concentration as a key variable controlling CO2 solubility and fluid density. This information is vital for modeling the long-term safety and efficiency of geological carbon storage.

Use Cases

• Modeling CO2 solubility in formation water based on total dissolved solid concentrations.
• Assessing the potential for long-term carbon storage via solubility trapping in specific basins.
• Analyzing fluid density changes to predict advection rates and CO2 migration in geological formations.

Strengths

• Compiled from over 900 individual well measurements, providing a regional-scale view.
• Focuses on key physical variables (TDS, pressure, temperature) directly relevant to CO2 storage safety.

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 sources.
