Proven Basin – Under-explored
100% Finder Exploration & Operator
Surface area: ~6,430km2
Water depth: less than 70m over the majority of the Permit
Exploration Permit NT/P 79 was awarded to Finder in June 2009. The Permit is located in the Joseph Bonaparte Gulf approximately 150 km west of Darwin in the Northern Territory. The area lies ~60km east of the Petrel Gas Field and to ~180km north of the Turtle and Barnett oil fields.
Potential Play-types
(i) Hanging wall fault traps of Permian age and older;
(ii) Reservoirs draping over basement morphologies;
(iii) Cretaceous truncation plays in the west of the Permit; and:
(iv) in the south of the Permit the potential exists for as yet unrecognised salt diapirs (due to the lack of data).

Geology of the Petrel Sub-basin
The Petrel Sub-basin is an asymmetric, northwest-southeast-trending Palaeozoic rift that occurs in the eastern portion of the Bonaparte Basin and extends onshore where it contains a succession of thick Palaeozoic and thinner Mesozoic sediments. The eastern and south-western margins of the sub-basin are flanked by platforms of relatively shallow basement and thin sediment cover. Sedimentation in the sub-basin commenced in the Cambrian and northeast-southwest rifting was initiated in the Late Devonian to Early Carboniferous. This is a proven hydrocarbon Basin, as evidenced by the Petrel, Tern, Blacktip gas fields and the Turtle and Barnett oil fields. Refer to the semi-regional 2D seismic section below for a generalisation of the key play concepts.
