Southern Petrel Sub-basin
Release Areas – NT13-4 and NT13-5
Bids close – 21 November 2013
- Proximal to the Blacktip gas fields and Blacktip pipeline
- Development/production plans are underway for the nearby Petrel, Tern and Frigate gas fields
- Shallow water depths, 10–90 m
- Proven plays in anticlines, tilted fault blocks and structural/stratigraphic traps, structures related to salt tectonics
- Multiple potential oil- and gas-prone source rocks and active petroleum systems within the region
- Special Notices apply, refer to Guidance Notes
Release Areas NT13-4 and NT13-5 are located in the Joseph Bonaparte Gulf, in the vicinity of the Petrel, Tern, Frigate and Blacktip gas fields; the latter commenced production via the Blacktip pipeline in 2009. Release Area NT13-5 is located partly within a marine reserve Special Purpose Zone (IUCN VI) and Multiple Use Zone (IUCN VI); for further information refer to Special Notices.
The Petrel Sub-basin in the southern Bonaparte Basin was formed during Paleozoic northeast–southwest extension and contains a thick succession of Paleozoic and Mesozoic sediments. Proven Permian petroleum systems in the region have charged the numerous gas accumulations. There is an oil and gas-prone early Carboniferous petroleum system, with Bonaparte Formation (Langfield Group) source rocks, in the inboard part of the sub-basin. The Release Areas offer a range of play types including early formed structures such as horst blocks and rotated fault blocks, as well as inversion-related anticlines. Stratigraphic traps are represented by pinch-outs and truncations across unconformities. Infrastructure in the region is expanding and will facilitate development of any new discovery.
