Gjøa A reliable host
The Gjøa platform, operated by Neptune, is located in the Q35 area of the North Sea, some 60 kilometres off the west coast 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 already the host for the Wintershall Dea Vega field, and will also be the host for the operated Nova field.
Gjøa is the first manned platform on the Norwegian Continental Shelf to take power from shore. Located just 60 kilometres off the coast, the Q35 area is a core region for Wintershall Dea.
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.
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.
