Neptune Energy Norge AS started drilling four production wells for the final development phase of Fenja field, 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.
The wells are being drilled by the Deepsea Yantai, a semisubmersible rig operated by Odfjell Drilling. The rig is set to drill into the reservoir sections, install the lower completions, and execute well clean-up activities. Drilling is estimated to take about 160 days.
The field is scheduled to come online in first-half 2023 and will produce about 28,000 boe/d at plateau.
Earlier this year, Neptune announced the installation and testing of electrically trace-heated (ETH) pipe-in-pipe which will transport oil from 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%).
