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 drill passed through 120 feet of Quaternary silt and limestone, 2124 feet of Mesozoic sandstone and siltstone, 1811 feet of Permian marine beds, partly of glacial origin, and 2541 feet of Lower Ordovician shale with sandstone at the base. The drill encountered Precambrian granite at 6610 feet, confirming the geophysical estimate of depth to basement. None of the sediments present in the well are considered likely to be a source for hydrocarbon accumulations. No signs of hydrocarbons were seen in this well.
