Neptune Energy said it had successfully drilled four development wells ahead of the start of production on the Fenja field in the Norwegian Sea.
PRODUCTION
The operator said that completion of the four wells marked an important milestone in the development of Fenja, which is scheduled to come on stream in the first quarter of 2023.
The field will produce approximately 28,000 barrels of oil equivalent per day (boepd) at plateau.
FENJA
The Fenja development consists of two subsea templates tied back to the Njord A platform via a production pipeline, water and gas injection pipelines and an umbilical.
The wells consist of two oil producers, one water injector and a gas injector. The gas injector will be converted to a gas producer towards the end of field life.
Neptune Energy’s director of projects & engineering in Norway, Erik Oppedal, said that the region near Fenja of the Norwegian Sea was a strategically-important growth area for Neptune, with high prospectivity.
PIPELINE
“Earlier this summer, Equinor, on behalf of Neptune, successfully pulled in the Fenja risers and dynamic umbilical to the host platform, Njord A, which is now back on the field,” added the company.
“Final tie-in activities will be completed shortly and all subsea facilities are ready.
“Fenja has been developed with an electrically trace-heated (ETH) pipe-in-pipe solution that will transport oil from the Fenja field to the Njord A platform.
“At 37 km, it is the world’s longest ETH subsea production pipeline.”
The Fenja oil and gas field is at a water depth of 325 metres, around 36 km southwest of the Equinor-operated Njord A platform.
PROJECT
Neptune holds a 22.5% owner share in Njord A which lies 120 km north of Kristiansund.
Odfjell Drilling drilled the wells using the Deepsea Yantai, a semi-submersible rig.
The Fenja partners comprise Neptune Energy (operator, 30%), Vår Energi (45%), Suncor Energy (17.5%) and DNO (7.5%).
