Start up from the P1 infill project in February and the Duva field tie-back increased production at UK-based Neptune Energy's Gjoa development to 42 million barrels of oil equivalent in 2021, compared with 40 million boe in 2020, the company has reported.

The Gjoa field has been producing in the Norwegian North Sea since 2010, and has taken on renewed importance due to a role as a hub platform for nearby discoveries.

Production from the tie-back field Vega, operated by Wintershall Dea, and also from the Gjoa field itself, has been better than expected, Neptune indicated.

Some 76% of this production was gas, all of which is exported through the FLAGS pipeline to the St. Fergus Gas Terminal in the UK.

Neptune Energy’s Head of Operations in Norway Martin Borthne said in a press release that the company’s plan to develop the Gjoa platform into a host facility and a hub for nearby discoveries has succeeded.

“This has not only prolonged the life of the Gjoa platform itself, but has resulted in far higher value creation than expected at start-up,” he said..

According to Borthne, Neptune expects to bring on stream a fourth tie-in field to the Gjoa facilities, linking to Wintershall Dea’s Nova field.

“In addition, we plan to drill two exploration wells in the area and continue to mature other nearby discoveries and exploration opportunities as tie-in candidates. We have high expectations that the Gjøa hub will be in operation to 2040 and continue to create value in this area of the North Sea for many years to come,” he said.

Licence partners at Gjoa are UK-based Neptune Energy (operator, 30%), Norwegian Petoro (30%), Wintershall Dea of Germany (28%) and Norwegian OKEA (12%).
