Western Australia's Samphire Marsh No. 1 Well was drilled to 6,664 feet as a stratigraphic and structural test in the South Canning Basin. The drill log details the thickness and composition of geological layers, including Quaternary, Mesozoic, Permian, and Lower Ordovician formations, and confirms Precambrian granite basement. The data, hosted by the Australian Ocean Data Network, indicates no signs of hydrocarbons were found in this well.
Use Cases
- Model subsurface stratigraphy based on detailed layer thicknesses and rock types.
- Assess petroleum source rock potential based on the described sediment composition and reported absence of hydrocarbons.
- Validate geophysical depth-to-basement estimates using the confirmed granite contact depth.
- Study glacial marine deposits within the Permian sequence described in the well log.
Strengths
- Provides a detailed stratigraphic column with specific depths for five major geological formations.
- Confirms a geophysical estimate by reporting Precambrian granite encountered at 6,610 feet.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last metadata update was 2026-06-17.
