Western Australia's Samphire Marsh No. 1 Well was drilled to a total depth of 6664 feet as a stratigraphic and structural test in the South Canning Basin. The dataset, published by the Australian Ocean Data Network, details the geological layers encountered, including Quaternary, Mesozoic, Permian, and Lower Ordovician formations, and confirms Precambrian granite basement. No signs of hydrocarbons were observed in this well.
Use Cases
- Modeling subsurface stratigraphy based on detailed layer depths and rock types.
- Assessing hydrocarbon source rock potential based on the described sediment composition.
- Calibrating geophysical depth-to-basement estimates using the confirmed granite contact depth.
- Studying the geological history of the South Canning Basin based on the sequence of Quaternary, Mesozoic, Permian, and Ordovician layers.
Strengths
- Provides a detailed stratigraphic column with specific depths for each geological layer (e.g., 120 feet of Quaternary, 2124 feet of Mesozoic).
- Confirms a geophysical estimate with a precise depth to basement (Precambrian granite at 6610 feet).
- Includes a clear conclusion regarding hydrocarbon potential based on the observed sediments.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to a single well location.
