- Several marginal fields have been discovered in the Ashmore and Cartier Islands Adjacent Area. These fields are Tenacious, Oliver, Montara, Bilyara, Tahbilk and Talbot.
- The Brewster structure is also a marginal field, located south of the Ashmore and Cartier Islands Adjacent Area.
- Blacktip-1 is a recent gas discovery, located in the Bonaparte Basin.
- These fields could be developed in the future if a "critical mass" of oil or gas reserves are found.
- Tenacious oil field was discovered in May 1997. The field extends across two permits.
- AC/P4 is held by:
*Wholly owned subsidiary of OMV Australia Pty LTD
- The Oliver oil and gas field was discovered in February 1988. It is now vacant acreage and may be released for bids in 2002.
- Reserves: 15 to 18 million barrels of liquid hydrocarbon and 335 to 345 billion standard cubic feet of gas (BCF)
- Development: Possible floating oil and condensate facility
3. Montara, Bilyara and Tahbilk
- Oil and gas fields were discovered in 1988, and are now under retention lease.
- AC/RL3 is held by:
Oil: Montara, Bilyara and Tahbilk - 30 million barrels of liquid hydrocarbon.
Gas: Montara, Bilyara and Tahbilk - 213 billion standard cubic feet of gas (BCF).
- Development: Floating methanol; Production, Storage and Offloading (MFPSO) facility being studied.
- Talbot oil field was discovered in 1989, under a retention lease.
- AC/RL1 is held by:
- Reserves: 2 to 5 million barrels
- Development: Possible use of Floating Production Barge for processing and storage with periodical offloading into a tanker.
- The Brewster structure consists of three fields - Dinichthys, Gorgonichthys and Titanichthys.
WA 285P is held by:
- Three commitment wells have been drilled - the first at Dinichthys, followed by Gorgonichthys and Titanichthys.
- These wells were drilled in 2000 and finished early 2001.
- A DST was conducted on Dinichthys and successfully ran 22 million standard cubic feet per day of gas plus 60 barrels per million condensate.
- Blacktip-1 was discovered in August 2001.
- It is situated approximately 300 kms South-West of Darwin in the Bonaparte Basin.
- WA/279P is held by:
- Five separate hydrocarbon bearing intervals with a cumulative gross thickness of 188 metres have been identified.
- The well was drilled to a total depth of 3181 metres and is situated at a water depth of 50 metres.
- The well achieved a maximum flow rate of 35 million standard cubic feet per day of dry, sweet gas.
- Reserves: The initial reserve estimate is 0.9 - 1.2 tcf.
