Australian Sedimentary Basin Formation Water Data for CO2 Solubility Trapping

The Variability in Formation Water Composition and its Implications for CO2 Storage Conditions dataset, from the Australian Ocean Data Network, assesses conditions for CO2 solubility trapping in major Australian sedimentary basins. It compiles total dissolved solid (TDS) concentration data from over 900 wells, along with pressure and temperature variables, to model CO2 solubility and fluid density changes. The dataset was last updated on 2026-04-10.

Use Cases

• Modeling CO2 solubility in formation water based on compiled TDS, pressure, and temperature data.
• Assessing the rate of solubility trapping and fluid migration based on calculated fluid density changes.
• Evaluating long-term CO2 storage safety in sedimentary basins based on the described trapping mechanisms.
• Comparing formation water chemistry across different Australian basins for storage site characterization.

Strengths

• Compiles data from over 900 wells, providing a substantial sample size for analysis.
• Focuses on key variables for CO2 solubility modeling: TDS, pressure, and temperature.
• Explicitly addresses four major CO2 trapping mechanisms relevant for storage safety assessment.

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.
