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

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 before encountering Precambrian granite at 6610 feet. No signs of hydrocarbons were observed in this well.

Use Cases

• Validate geophysical depth-to-basement estimates based on the encountered Precambrian granite.
• Analyze the stratigraphic column and sediment thicknesses for regional geological modeling.
• Assess hydrocarbon source rock potential based on the described sediment lithologies.
• Study the sequence of geological periods (Quaternary to Precambrian) present at this location.

Strengths

• Total well depth is precisely recorded as 6664 feet.
• Detailed stratigraphic column with thicknesses for four major geological units is provided.
• Confirms the geophysical estimate of basement depth at 6610 feet.

Limitations

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