<p>A regional mapping program conducted by Geoscience Australia addressed stratigraphic and structural aspects of exploration risk within the Triassic succession of the Roebuck Basin and parts of the adjacent sub-basins (central North West Shelf, Figure 1). <p>Seismic horizons of regional significance were mapped using 2D and 3D seismic surveys. Seismic survey coverage is shown in Figure 1. 2D surveys include regional deep surveys such as AGSO s110, AGSO s120, and PGS New Dawn. 3D surveys include Admiral, Beagle, CNOOC, Curt, Lord, Naranco, Polly, Whitetail, and a 5 x 5 km extract (used with permission) from the TGS Capreolus MC3D. Synthetic seismograms (Nguyen et al., 2019) were used to tie seismic horizons to wells. <p>The mapped horizons are placed within a regional tectonostratigraphic framework by Abbott et al. (2019, their Figure 2). This data pack comprises seismic horizon grids and isochron grids generated from the TR10.0_SB (base Triassic), TR17.0_SB (Mid–Triassic), and J10.0_SB (top Triassic) seismic horizons (Figure 2). Fault maps compiled at the TR10.0 _SB and J10.0_SB are also included.

Exploring for the Future (EFTF) is a multiyear (2016–2024) initiative of the Australian Government, conducted by Geoscience Australia. This program aims to improve Australia’s desirability for industry investment in resource exploration of frontier regions across Australia. This paper will focus on the science impacts from the EFTF program in northern Australia derived from the acquisition and interpretation of seismic surveys, the drilling of the NDI Carrara 1 and also complementary scientific analysis and interpretation to determine the resource potential of the region. This work was undertaken in collaboration with the Northern Territory Geological Survey, the Queensland Geological Survey, AuScope and the MinEx CRC. These new data link the highly prospective resource rich areas of the McArthur Basin and Mt Isa Province via a continuous seismic traverse across central northern Australia. The Exploring for the Future program aims to further de-risk exploration within greenfield regions and position northern Australia for future exploration investment. [Carr] The Sherbrook Supersequence is the youngest of four Cretaceous supersequences in the Otway Basin and was deposited during a phase of crustal extension. This presentation shows how a basin-scale gross depositional environment (GDE) map for the Sherbrook SS was constructed, the significance of the map for the Austral 3 petroleum system, and why GDE mapping is important for pre-competitive basin studies at Geoscience Australia.
