Samphire Marsh No. 1 Well is a stratigraphic and structural test drilled by West Australian Petroleum Pty Limited in the South Canning Basin. The well reached a total depth of 6664 feet, passing through Quaternary, Mesozoic, Permian, and Lower Ordovician formations before encountering Precambrian granite. The dataset, hosted by the Australian Ocean Data Network, indicates no hydrocarbon potential was found in this location.
Use Cases
- Model subsurface stratigraphy based on detailed lithological layer thicknesses.
- Validate geophysical depth-to-basement estimates based on the granite encounter depth.
- Assess hydrocarbon source rock potential in the South Canning Basin based on the described sediments.
Strengths
- Total depth of 6664 feet provides a significant vertical profile.
- Lithological layers are described with specific thicknesses (e.g., 120 feet of Quaternary silt and limestone).
- Depth to Precambrian basement (6610 feet) is confirmed by drilling.
Limitations
- Row count and column-level documentation are unknown.
- The description explicitly states no hydrocarbon signs were found, limiting its use for petroleum resource studies.
- Data freshness should be verified; last updated metadata is 2026-05-05.
