Location

Areas W07-18 to W07-21 lie approximately 150–250 km offshore Dampier, Western Australian, in 80–500 m water depth, increasing to 1000 m in the outer northwest portion of Area W07-18 (Figure 1). The release areas occur within the Beagle Sub-basin, the northern most depocentre of the Northern Carnarvon Basin. The nearest production facilities are the Mutineer/Norfolk and Exeter accumulations at the adjacent northern margin of the Dampier Sub-basin, which began production via a floating production, storage and offload facility (FPSO) in 2005. Development of the Angel gas field, also within the Dampier Sub-basin approximately 25 km south of Mutineer/Norfolk, and pipeline to the trunkline at the North Rankin platform is currently underway, and is expected to be fully operational by the end of 2008.

Area W07-18 comprises 45 graticular blocks, covers an area of 3,645 km² and contains 3 wells (Delambre 1, Ermine 1 and Serval 1).
Area W07-19 comprises 51 graticular blocks, covers an area of 4,130 km² and contains 3 wells (Grey Rabbit 1, Manaslu 1 and Picard 1).
Area W07-20 comprises 49 graticular blocks, covers an area of 3,970 km² and contains 7 wells (Cimba 1, Darwin 1, Depuch 1, Halo 1, Huascaran 1, Nebo 1 and North Turtle 1).
Area W07-21 comprises 34 graticular blocks, covers an area of 2,750 km² and contains 6 wells (Cossigny 1, De Grey 1, Jarman 1, Ronsard 1, Tayra 1 and Trafalgar 1; Sable 1 lies approximately 230 m west of this release area).

Areas W07-18 to 21 form part of previous permits WA-270-P and WA-292 to WA-295-P, which were awarded following acreage release offered in 1996 and 1998, respectively. These permits were subsequently relinquished during 2003–2005. No new acreage has been released in the Beagle Sub-basin since then, apart from one release area in 2003 (W03-8) across the De Grey Nose that included the Cossigny 1 and de Grey 1 well sites on the southern margin of the sub-basin; no bids were received for that area. The only current permits in the sub-basin are WA-191-P, WA-352-P and WA-291-P along the far southern and south-eastern margins of the sub-basin, and WA-294-P and WA-296-P, which cover a small portion of the far western and northeastern parts of the sub-basin, respectively (Figure 1).
