Gjøa A reliable host

Located in the northern North Sea, Gjøa is in a core region for Wintershall Dea. The operated Vega and Nova fields are both Gjøa satellites.

The Gjøa platform, operated by Neptune, is located in the northern North Sea, some 45 kilometres off the west coast of the city of Florø. The field is developed with four subsea templates at a water depth of 360 metres, tied to a semi-submersible production and processing plant. Gjøa is the host for Wintershall Dea Vega and Nova field.

Power from shore

Gjøa is the first floating platform on the Norwegian Continental Shelf to take power from shore. Located 45 kilometres off the coast, the Q35 area is a core region for Wintershall Dea.

Reservoir and recovery

The Gjøa reservoir contains gas above a thin oil zone in Jurassic sandstone in the Dunlin, Brent and Viking Groups. The reservoir depth is 2,200 metres. The field is exploited by pressure depletion. In the southern segments, oil production was prioritised in the first years. Production of the gas cap started in 2015. Low-pressure production was implemented in 2017.

Export of hydrocarbons

The oil from Gjøa and the satellite fields are transported via the Troll Oil Pipeline II to Mongstad. Rich gas is transported via the FLAGS pipeline to St Fergus in the UK.

Gjøa P1

The Gjøa P1 fast track development project successfully started production on February 2021. This project aimed to develop untapped reserves in the northern P1 segment of the Gjøa field at a water depth of 3­­40 metres. The P1 segment increased the remaining developed reserves at Gjøa by 30%.
