Neptune Energy Norge AS finished drilling on Fenja field in preparation for production start-up. The field lies 36 km southwest of Njord A platform in 325 m of water in the Norwegian Sea.
Fenja consists of two subsea templates tied back to Njord A via a production pipeline, water and gas injection pipelines, and an umbilical. The wells are planned as 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.
Four production wells were drilled by the Deepsea Yantai, a semisubmersible rig operated by Odfjell Drilling (OGJ Online, Oct. 26, 2021).
The field is scheduled to come on stream in first-quarter 2023 and will produce about 28,000 boe/d at plateau.
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. Final tie-in activities will be completed shortly, and all subsea facilities are ready, the company said. 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.
Neptune Energy is operator at Fenja (30%) with partners Vår Energi AS (45%), Suncor Energy Norge AS (17.5%), and DNO Norge AS (7.5%).
