L030 seismic reflection survey in the Sydney basin, NSW, 1957

Between February and May, 1957, an experimental seismic reflection survey was made in the Sydney Basin by the Bureau of Mineral Resources to test the applicability of the method in that area and to investigate the sedimentary section. The work done at four different locations is described and the seismic results obtained are discussed in relation to the known geology. In general, the seismic method proved applicable in the Sydney Basin. The use of multiple geophone and shot-hole techniques proved desirable in some areas, notably on the Hawkesbury Sandstone. The seismic work indicated the existence of sediments up to 15,000 feet thick. Insufficient seismic work was done to prove the existence of individual structures suitable for the accumulation of oil or gas.
