Australian Sedimentary Basin Formation Water Composition for CO2 Storage Assessment

Over 900 wells across major Australian sedimentary basins provide data on formation water total dissolved solids (TDS). Compiled by the Australian Ocean Data Network, this dataset assesses conditions for CO2 solubility trapping, a key mechanism for long-term carbon storage. The data supports modeling of fluid density changes and advection rates critical for storage safety.

Use Cases

• Model CO2 solubility in formation water based on TDS, pressure, and temperature variables.
• Assess fluid density changes and advection rates for storage safety simulations.
• Evaluate long-term trapping mechanisms (structural, residual, solubility, mineral) across different basins.
• Compare regional geological properties influencing CO2 storage safety across Australian sedimentary basins.

Strengths

• Data compiled from over 900 wells provides a substantial sample size.
• Focuses on key variables (TDS, pressure, temperature) controlling CO2 solubility and fluid density.

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.
