Neptune Energy has confirmed a marked increase in production from its operated Gjoa platform.
From 2020 to 2021, production from the installation in the Norwegian North Sea rose by two million barrels of oil equivalents (boe).
Gjoa’s gross production ended on 42 million boe in 2021, compared with 40 million boe in 2020.
More than three quarters of the platform’s output was gas, all of which is exported through the FLAGS pipeline to the St Fergus gas terminal in Aberdeenshire.
The increase was due mainly to start-up from the Gjoa P1 infill development in February, as well as the Duva field tie-back in August.
In addition, production from the tie-back field Vega, operated by Wintershall Dea, and the Gjoa field itself, has exceeded expectations.
Estimated reserves on the Gjoa field have increased by 38% since the plan for development and production was approved in 2007.
Neptune Energy’s head of operations in Norway Martin Borthne said: “Our ambition to develop the Gjøa platform into a host facility and a hub for nearby discoveries has succeeded.
“This has not only prolonged the life of the Gjøa platform itself, but has resulted in far higher value creation than expected at start-up.
“Successful utilisation of the Gjøa infrastructure as a hub is further seen as a critical enabler for continued exploration and development in this part of the North Sea.”
He added: “This year we expect to bring on stream a fourth tie-in field to the Gjøa facilities – 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.”
