Gjøa (No)

Gjøa is ENGIE E&P's first production operatorship on the Norwegian continental shelf.

Gjøa is a gas field in the North Sea, 60 kilometres west of Florø in Norway.

Gjøa is a gas field in the North Sea, 60 kilometres west of Florø. The reservoir sits on top of a thin oil rim, and contains an estimated 40 billion cubic metres of gas reserves. The semi-submersible production unit has full processing and export capabilities. Oil is exported to the Mongstad crude oil terminal. Export of gas ends up at the St. Fergus gas terminal in Scotland.

Since start-up in 2010, the ENGIE E&P Norge-operated Gjøa platform has had outstanding results both on production as well as on operational performance. To date in 2016, Gjøa runs with a production regularity above 98 per cent, and has increased the gas export rate to 20 MSm³/d, 17.5 per cent more than estimated.

Due to good reservoir management, Gjøa is set to produce 60 million barrels of oil equivalents more than estimated at start of production. Yet, it still has capacity to handle extra resources.

Norsk Hydro discovered the field in 1989, and ENGIE E&P acquired a 30% interest in the field in 2003. In June 2007, Norwegian authorities approved the plan for development and operation of Gjøa, clearing the way for one of the largest offshore developments in Norway since Snøhvit and Ormen Lange. The field was developed through a joint operatorship with Statoil.
