Otter is a development of five subsea wells which are tied back to the Shell Expro-operated Eider platform. It is located in the Northern North Sea, 150km north-east of Shetland in a water depth of 182m. TOTAL E&P UK Limited is operator of Otter field on behalf of the block licensees.
Hydrocarbons are exported from Otter via the Eider platform to North Cormorant. The oil is then sent to the Sullom Voe Oil Terminal in Shetland via the Brent system and the gas is sent to the St Fergus Gas Terminal via the FLAGS system.
Otter is one of the North Sea's most northerly fields. It is also one of the deepest subsea tie-backs in the North Sea. It is a good example of how technical innovation and ongoing commercial effectiveness within the industry can unlock the stranded reserves of the UKCS. Otter not only added new reserves but also extended the life of its host, the Eider field.
