Brief description

The Officer Basin project was a co-operative project jointly conducted by Geoscience Australia (GA) and the South Australian Department of Mines and Energy (DMESA) as part of the National Geoscience Mapping Accord (NGMA). The goals of the 1993 seismic acquisition in the Officer Basin were to provide a regional network of traverses to develop a cross section and evaluate basin morphology. The acquisition was designed to image the basin fill, with the aim of extending the stratigraphic control in the eastern Officer Basin into the central portion of this basin. The survey comprised five lines totalling 550 km in length.
