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

6664 feet of stratigraphic and structural data from the Samphire Marsh No. 1 Well in the South Canning Basin, Western Australia. The well was drilled by West Australian Petroleum Pty Limited and documented by the Australian Ocean Data Network. It penetrated Quaternary, Mesozoic, Permian, and Lower Ordovician sediments before reaching Precambrian granite at 6610 feet.

Use Cases

• Analyze sedimentary thickness and lithology variations based on the described Quaternary silt, Mesozoic sandstone, Permian marine beds, and Lower Ordovician shale
• Evaluate basement depth estimates by comparing the geophysical prediction with the actual granite encounter at 6610 feet
• Assess hydrocarbon source potential using the reported absence of hydrocarbon signs and source rock indications
• Correlate stratigraphic columns across the South Canning Basin using the detailed depth intervals for each geological unit

Strengths

• Detailed depth measurements for each geological unit (e.g., 120 feet of Quaternary, 2124 feet of Mesozoic, 1811 feet of Permian, 2541 feet of Lower Ordovician)
• Confirmation of geophysical basement depth estimate with actual granite encounter at 6610 feet
• Clear statement of hydrocarbon potential assessment with negative result

Limitations

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