Samphire Marsh No. 1 Well: Stratigraphic Test in South Canning Basin

Western Australia's Samphire Marsh No. 1 Well was drilled to a total depth of 6664 feet as a stratigraphic and structural test in the South Canning Basin. The drill passed through Quaternary, Mesozoic, Permian, and Lower Ordovician sediments, encountering Precambrian granite at 6610 feet. The data was published by Geoscience Australia Data and last updated in May 2026.

Use Cases

• Validate geophysical depth-to-basement estimates based on the confirmed granite contact at 6610 feet.
• Model regional stratigraphy based on the described thicknesses of Quaternary, Mesozoic, Permian, and Ordovician layers.
• Assess hydrocarbon source rock potential in the South Canning Basin based on the description of encountered sediments.
• Calibrate subsurface interpretations using the detailed lithological sequence from silt and limestone to sandstone and shale.

Strengths

• Provides a precise total drilling depth of 6664 feet.
• Contains detailed stratigraphic column with layer thicknesses (e.g., 120 feet of Quaternary silt and limestone).
• Confirms a geophysical estimate with a direct measurement of Precambrian granite at 6610 feet.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
