Deep Formation Water Salinity in the Canning Basin

Salinity data for deep formation water in Western Australia's Canning Basin, estimated from well logs or measured from oil-production wells and drill stem tests. The dataset covers salinity ranges from near-fresh (<1000 mg/L TDS) to brine (>300,000 mg/L TDS), with detailed spatial and stratigraphic analysis. It was published by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Model salinity-depth relationships using depth and stratigraphic unit data to understand paleo-hydrological conditions.
• Analyze spatial salinity patterns, such as high concentrations in the Willara and Kidson Sub-Basins, for basin-scale geochemical mapping.
• Investigate the influence of evaporite dissolution, referenced in the Grant Group and Carribuddy Formation, on present-day water chemistry.
• Correlate salinity anomalies with specific lithologies like the low-permeability Mellinjerie Limestone to study fluid retention.
• Study temporal stacking of paleo-salinity profiles across marine-continental depositional cycles described in the stratigraphic record.

Strengths

• Covers a wide salinity range from <1000 mg/L to >300,000 mg/L Total Dissolved Solids.
• Provides detailed geological context linking salinity to specific sub-basins, formations, and depositional environments.
• Includes analysis of salinity variation with depth and across stratigraphic units.

Limitations

• Specific row count, column names, and sample size are unknown.
• Data is presented in PDF/HTML formats, limiting machine-readability and direct analysis.
• Geographic coverage is focused on the Canning Basin, Western Australia, limiting broader applicability.
