Australian Sedimentary Basin Formation Water Composition for CO2 Storage Assessment

A compilation of total dissolved solid (TDS) concentration data from over 900 wells across major Australian sedimentary basins. The dataset, from Geoscience Australia, assesses conditions for CO2 solubility trapping, a key mechanism for long-term carbon storage. It was last updated on 2026-04-20.

Use Cases

• Modeling CO2 solubility in formation water based on TDS, pressure, and temperature variables.
• Assessing the potential for fluid density-driven advection and downward CO2 migration in storage sites.
• Evaluating the long-term safety of CO2 storage projects based on regional geological properties.
• Comparing solubility trapping conditions across different Australian sedimentary basins.

Strengths

• Data compiled from over 900 wells, providing a substantial sample size.
• Focuses on key variables for CO2 solubility modeling: TDS, pressure, and temperature.

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, focusing on Australian basins.
