Seagull will initially produce around 50,000 boe/d (80% oil), and is expected to produce for 10 years. Proven plus probable gross reserves are estimated at 50 MMboe.
The field, in license P1622, block 22/29C, will be tied back to the BP-operated ETAP Central Processing Facility (CPF) 17 km (11 mi) to the south, partly using existing subsea infrastructure that would otherwise have been decommissioned.
Produced gas will land ashore at the CATS processing terminal at Teesside, northeast England, while the oil will head through the Forties Pipeline System to the Kinneil Terminal, Grangemouth, central Scotland.
Neptune acquired its 35% operated interest in Seagull from Apache North Sea in 2018.
