Neptune Energy has commenced production from Fenja oil and gas field in the Norwegian Sea.
The field, which lies 120 km north of Kristiansund at water depth of 325 m, is expected to produce 35,000 boe/d gross, via two oil producers, with pressure support from one water injector and one gas injector.
The development consists of two subsea templates tied back to the Equinor-operated Njord A platform. A 36 km electrically trace-heated (ETH) pipe-in-pipe solution transports oil from Fenja to the platform for processing and transport. Due to the high wax content of Fenja field’s oil, the contents of the pipeline must be warmed up to a temperature above 28 degrees Celsius before starting the flow after a shut down.
During normal production, the temperature in the pipeline is well above this temperature. The tie-back to Njord A is the world’s longest ETH subsea production pipeline, Neptune said.
Total reserves are estimated at 50-75 MMboe, of which 75% is oil and 25% is gas.
Neptune Energy is operator of the license with 30% interest. Partners are Vår Energi ASA (45%), Sval Energi AS (17.5%), and DNO (7.5%).
