Regional Geology of the Bonaparte Basin

The Bonaparte Basin represents Australia’s easternmost offshore province of the Westralian Superbasin comprising also the Browse, Roebuck, Offshore Canning and Northern Carnarvon basins, collectively known as basins of the North West Shelf (Figure 1). Located predominantly offshore (Figure 2), the Bonaparte Basin contains a Paleozoic, Mesozoic and Cenozoic sedimentary succession that exceeds 15 000 m in thickness in the southern portion (“Petrel Sub-basin”) and a Mesozoic-Cenozoic basin fill in the northern part. Since the development of the Bayu-Undan and Blacktip gas discoveries (1995 and 2001 respectively) and first oil discoveries in the Vulcan Sub-basin (Jabiru in 1986; Challis and Cassini in1989), the basin has been an established oil and gas province.
