Bonaparte Basin Regional Geology

Regional Geology of the Bonaparte Basin

The Bonaparte Basin is located predominantly offshore (Figure 1) and covers an area of approximately 270 000 km2 on Australia’s northwestern continental margin. It contains a Paleozoic, Mesozoic and Cenozoic sedimentary succession that exceeds 15 000 m in thickness and hosts significant reserves of oil and gas. Gas in the Bonaparte Basin is currently produced from the Bayu/Undan and Blacktip fields and oil is produced from the Laminaria/Corallina and greater Montara fields (Figure 2).
