Gjøa - OKEA


Gjøa is an oil and gas field located in the northern part of the North Sea. The water depth is 360 metres. Gjøa was discovered in 1989, and the plan for development and operation (PDO) was approved in 2007. The production started in 2010. The field is partly supplied with power from shore. The Vega, Duva and Nova fields are tied-back to Gjøa for processing and further export.

Gjøa is developed with a semi-submersible production facility and includes five 4-slot templates. In 2019, Gjøa was granted a PDO exemption for the redevelopment of the P1 segment, including a 4-slot template.


The reservoir contains gas above a relatively thin oil zone in sandstone of Jurassic age in the Dunlin, Brent and Viking Groups. The field comprises several tilted fault segments with partly uncertain communication and variable reservoir quality. The reservoir depth is 2,200 metres.


The field is produced by pressure depletion. In the southern segments, oil production was prioritised in the first years. Gas blow-down, production of the gas cap, started in 2015. Low pressure production was implemented in 2017.


Stabilised oil is exported by pipeline connected to Troll Oil Pipeline II, for further transport to the Mongstad terminal. Rich gas is exported via the Far North Liquids and Associated Gas System (FLAGS) on the UK continental shelf, for further processing at the St Fergus terminal in the UK.
