Figure 4. Detail of index map of USGS Province 3948 Northwest Shelf, Australia. Fields are shown and wells and fields mentioned in the text are labeled.
Figure 5. West-East cross section showing sub-basins developed between the Pilbara Block and the Exmouth Plateau. Triassic rocks have been cut off by the formation of the Gascoyne Abyssal Plain. The oil window is shown at 3-4 km depth on the East. Well total depths are in meters. The location of this cross section is marked on Figure 2. Modified from Barber, 1988.
Figure 6. Burial history plots for the Barrow sub-basin(a) and the Exmouth Plateau(b). The zone of maximum hydrocarbon generation is between vitrinite reflectance values of 0.60 Ro% and 1.00 Ro%. Modified from Barber, 1988.
