Australian Sedimentary Basin Formation Water Composition for CO2 Storage Assessment

Over 900 well measurements of total dissolved solid concentration in formation water, compiled to assess conditions for CO2 solubility trapping in major Australian sedimentary basins. The dataset, hosted by the Australian Ocean Data Network, was last updated in April 2026 and supports research into geological carbon storage safety.

Use Cases

• Model CO2 solubility in formation water based on compiled TDS, pressure, and temperature variables.
• Assess the rate of fluid advection and downward migration for solubility trapping based on fluid density data.
• Evaluate long-term CO2 storage safety across different Australian sedimentary basins based on regional geological properties.
• Compare the relevance of four major trapping mechanisms (structural, residual, solubility, mineral) over different timescales.

Strengths

• Data compiled from over 900 wells provides a substantial sample for analysis.
• Focuses on key variables controlling CO2 solubility: TDS concentration, pressure, and temperature.
• Assesses conditions across major Australian sedimentary basins for regional comparison.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and HTML formats, which may require extraction for computational analysis.
