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

Samphire Marsh No. 1 Well is a stratigraphic and structural test well drilled by West Australian Petroleum Pty Limited in the South Canning Basin, Western Australia. It reached a total depth of 6664 feet, passing through Quaternary, Mesozoic, Permian, and Lower Ordovician rock layers before hitting Precambrian granite basement. The dataset, hosted by the Australian Ocean Data Network, indicates no signs of hydrocarbons were found in this well.

Use Cases

• Modeling basin stratigraphy based on detailed layer thicknesses and rock types.
• Calibrating geophysical depth estimates to basement based on the granite encounter at 6610 feet.
• Assessing regional hydrocarbon source rock potential based on the description of encountered sediments.

Strengths

• Provides specific depth measurements for multiple geological layers, including 120 feet of Quaternary and 2541 feet of Lower Ordovician.
• Confirms a geophysical estimate with a direct measurement, hitting Precambrian granite at 6610 feet.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
