UK-based Neptune Energy, with its partners Vår Energi, Sval Energi and DNO, has started production from the Fenja oil and gas field

With the help of two oil producers, one water injector, and one gas injector, Fenja is expected to produce 35,000 barrels of oil equivalent per day (boepd).

The oil and gas field is located in the Norwegian Sea 120 km north of Kristiansund at a depth of 350 metres.

Neptune Energy, which has a 30% stake in the project, is the operator of the field.

Vår Energi controls a 45% stake in the project, whereas Sval Energi and DNO own 17.5% and 7.5% stake, respectively.

The project comprises two subsea templates connected to the Njord A platform, which is run by Equinor.

Oil is transported from the Fenja field to the platform for processing and transportation via a 36 km electrically trace-heated (ETH) pipe-in-pipe solution.

As the oil from the Fenja field contains wax, it must be warmed up before the flow can be restarted after a shutdown.

Neptune Energy Managing Director in Norway and the UK Odin Estensen said: “The Fenja development is an excellent example of how our industry uses innovative technologies to overcome challenges.

“The ETH pipe-in-pipe solution is crucial for transporting the oil and is a creative, cost-effective approach that enables the field to be tied back to existing infrastructure. Fenja is also located in a strategically important growth area for Neptune Energy, with a number of other interesting prospects nearby.”

The oil field is estimated to have between 50 and 75 million boe, with 75% being oil and 25% gas.

Last week, Neptune Energy said it has begun gas production from the 11th well in the Cygnus gas field, which is located in the North Sea.
