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

Samphire Marsh No. 1 Well was drilled to a total depth of 6,664 feet as a stratigraphic and structural test. The detailed log describes the thickness and composition of geological layers, including Quaternary, Mesozoic, Permian, and Lower Ordovician formations, and confirms the depth to Precambrian granite. This dataset is provided by Geoscience Australia and was last updated in April 2026.

Use Cases

• Modeling subsurface geology based on the described stratigraphic column and layer thicknesses.
• Assessing hydrocarbon source rock potential based on the description of sediment types and the reported absence of signs.
• Calibrating geophysical depth estimates using the confirmed depth to Precambrian basement rock.
• Studying the geological history of Western Australia based on the sequence of Quaternary, Mesozoic, Permian, and Ordovician layers.

Strengths

• Provides a precise total drilling depth of 6,664 feet.
• Contains a detailed breakdown of geological layer thicknesses, such as 2,124 feet of Mesozoic sandstone and siltstone.
• Confirms a geophysical estimate by encountering Precambrian granite at 6,610 feet.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description states no signs of hydrocarbons were seen, which limits its use for petroleum discovery.
