In mid-1991, the Bureau of Mineral Resources (BMR) commenced a program of deep seismicacquisition on the southern North West Shelf with the intention of providing a regionalframework data set for explorers in this highly prospective segment of Australia's continentalmargin. In particular, the program has the following aims: To determine the broad regional structural framework of the southern North West Shelfby examining the boundaries between the major structural elements; To determine the deep crustal structure of the region; To assess the control of deep structure on the development of the major hydrocarbon fields and plays, and in particular the structural and depositional effects resulting fromreactivation of these structures; and To acquire a set of high-quality seismic tie lines linking the deeper exploration wellsthroughout the region to allow regional seismic correlations. To address these aims, a multi-cruise program has been devised during which deep seismicdata (4800 m streamer; 16 sec record length; 3000 cu in seismic source) are being recorded.During the first cruise, SNOWS-I ( for Southern North West Shelf), completed in June 1991,1654 km of seismic data were acquired aboard the BMR's research vessel Rig Seismic along10 widely spaced lines tied to 20 exploration wells in the Barrow, Dampier, and ExmouthSub-basins, and on the inner flank of the Exmouth Plateau. Processing of the data was ar-ranged through a commercial contractor. The data were processed by the second quarter of1992, and frequently show basin structure down to a depth of at least 10 s TWT (>20 km);these are the first data recorded on the southern North West Shelf that show such deep structures.
