Samphire Marsh No. 1 Well: Stratigraphic Drilling Log from the 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 record details the geological formations encountered, including 120 feet of Quaternary silt and limestone, 2124 feet of Mesozoic sandstone and siltstone, 1811 feet of Permian marine beds, and 2541 feet of Lower Ordovician shale. This dataset is provided by Geoscience Australia Data and was last updated in April 2026.

Use Cases

• Modeling subsurface geology based on the detailed stratigraphic column described.
• Assessing hydrocarbon source rock potential based on the reported absence of promising sediments.
• Calibrating geophysical depth-to-basement estimates using the confirmed Precambrian granite contact at 6610 feet.
• Studying the geological history of Western Australia based on the sequence of Quaternary, Mesozoic, Permian, and Ordovician layers.

Strengths

• Provides a detailed, foot-by-foot breakdown of geological formations down to 6664 feet.
• Includes a specific confirmation point (6610 feet) for the Precambrian basement, validating geophysical estimates.
• Contains explicit findings regarding the absence of hydrocarbon signs, which is a clear data point for exploration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data is specific to a single well, limiting broader regional analysis without additional sources.
