Samphire Marsh No. 1 Well Stratigraphic Drilling Log

Geoscience Australia Data provides a detailed stratigraphic log for the Samphire Marsh No. 1 Well in Western Australia. The well was drilled to a total depth of 6,664 feet as a structural test in the South Canning Basin. The log documents lithology and thickness for Quaternary, Mesozoic, Permian, and Ordovician geological units.

Use Cases

• Analyze the thickness of Quaternary silt and limestone (120 feet) versus Mesozoic sandstone and siltstone (2,124 feet) for basin sedimentation studies.
• Validate geophysical depth estimates by comparing the encountered Precambrian granite at 6,610 feet to predicted basement depth.
• Assess hydrocarbon potential by examining the documented absence of source sediments and hydrocarbon signs in the Permian marine beds and Lower Ordovician shale.

Strengths

• Provides a precise total drilling depth of 6,664 feet.
• Contains detailed lithological and thickness data for four major geological periods.
• Includes a specific finding confirming the geophysical estimate of basement depth at 6,610 feet.

Limitations

• Dataset is a single well log, limiting statistical or regional analysis.
• Data is presented in document formats (HTML, PDF) requiring manual extraction for computational use.
• No columnar or sample data is provided for direct tabular analysis.
