Over the last five years, the Onshore Energy Security Program, funded by the Australian Government and conducted by Geoscience Australia, has acquired deep seismic reflection data, in conjunction with state and Territory geological surveys, across several frontier sedimentary basins to stimulate petroleum exploration in onshore Australia. Here, we present data from two seismic lines collected in Western Australia in 2011. The Yilgarn-Officer-Musgrave (YOM) seismic line, 487 km long, crossed the western Officer Basin in Western Australia, and the Southern Carnarvon Seismic line, 259 km long, crossed the Byro Sub-basin of Southern Carnarvon Basin. The YOM survey aims to image the Neoproterozoic to Devonian western Officer Basin, one of Australia's underexplored sedimentary basins with hydrocarbon potential. The survey data will also build on the geoscientific knowledge of the architecture of Australia's crust and the relationship between the eastern Yilgarn Craton and the Musgrave Province. The Southern Carnarvon survey aims to image the in the onshore section of the Ordovician to Permian Carnarvon Basin, which offshore is one of Australia's premier petroleum producing provinces. The Byro Sub-basin is an underexplored depocentre with the potential for both hydrocarbon and geothermal energy. Where the seismic crosses the Byro Sub-basin it images a pair of half graben on west dipping faults. Structural and sequence stratigraphic interpretations of the two seismic lines will be presented here.
