New seismic data obtained in surveys off the West Australian coast will provide unprecedented opportunities for Australia's petroleum exploration and investment industry.

The release of pre-competitive seismic data and seafloor mapping studies of frontier areas off Australia’s west coast - including some of the Extended Continental Shelf acquired in 2008 - will inform the petroleum acreage release process for 2010 and future years and result in new exploration well beyond existing horizons.

The survey acquired about 7300 kilometres of seismic reflection data from the Mentelle Basin off Bunbury, the Zeewyck and Houtman sub-basins within the Perth Basin, the Carnarvon Basin and the Wallaby Plateau.

More than 11 700 kilometres of existing seismic data was also reprocessed to provide information which will enhance understanding of the region’s geology.

Minister Ferguson said: “These surveys play a vital role in supporting the Australian Government’s efforts to secure investment in energy resources for the future and create a strong economic outlook for all Australians.

While this survey will be the last new data acquisition under the Offshore Energy Security Program and the New Petroleum Program, Geoscience Australia's focus over the next year will be to mine and reprocess the significant data it has now collected to extract as much value as possible and strategically target future work programs to enhance Australia's long-term energy security."

Release of the data has been made as part of the Australian Government's Energy Security Initiative carried out by Geoscience Australia under its Offshore Energy Security Program.

The data from the surveys are available in the Southwest Margin Data Package.
