Bonaparte Basin Regional Geology

The Bonaparte Basin is located predominantly offshore (Figure 1) and covers an area of approximately 270 000 km2 on Australia’s northern continental margin. It contains a Paleozoic, Mesozoic and Cenozoic sedimentary succession that exceeds 15 000 m in thickness and is an established oil and gas province. 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). The Petrel‑Tern‑Frigate, Barossa‑Caldita and Cash‑Maple, Greater Sunrise and Evans Shoals gas fields are currently being considered for development.
