Britannia – 58.7% operator
Britannia in Block 16/26 of the UK central North Sea sits approximately 210-kilometres north east of Aberdeen. The complex consists of a drilling, production and accommodation platform, a long-term compression module of mono-column design and a 90-metre bridge connected to a production and utilities platform. Britannia is one of the largest natural gas and condensate fields in the North Sea. Commercial production began in 1998. Condensate is delivered through the Forties Pipeline to the oil stabilisation and processing plant at Kerse of Kinneil near Grangemouth and natural gas is transported through a dedicated Britannia pipeline to the Scottish Area Gas Evacuation (SAGE) facility at St Fergus.
Brodgar – 87.5% operator
Brodgar is a gas condensate accumulation located in Block 21/3a. This subsea development lies approximately 41 kilometres west of Britannia and produces via a subsea tie-back to the Britannia Bridge Linked Platform (BLP). Brodgar is controlled remotely from Britannia.
Callanish – 83.5% operator
The Callanish field lies approximately 25-kilometres from Britannia in Blocks 15/29b and 21/4aN. It was developed as a subsea tie-back to the Britannia BLP. It comprises two accumulations; a main field, which was discovered in 1999 and an outlier to the west separated by a structural saddle. Callanish is controlled remotely from Britannia.
Enochdhu – 50.0% operator
Enochdhu in Block 21/5a is a single well subsea tie-in to the Callanish manifold, which sits around 8-kilometres south-east of it. First production was achieved from Enochdhu in 2015.
Alder – 26.3% non-operated
Alder lies approximately 160-kilometres from the Scottish coastline and 60 kilometres from the UK median line. It is a high pressure, high temperature (HP/HT) gas condensate field, which was developed via a single subsea well tied back to the Britannia BLP via a 28-kilometre production flowline. Fluids from Alder are processed on a dedicated module attached to the BLP prior to export.
Finlaggan – third party tie-back
Finlaggan gas condensate field in Licence P2013, Block 21/05c is a two-well subsea tie-back development to Britannia with operator Zennor Petroleum.
