Neptune Vitality – together with its companions Vår Energi, Sval Energi, and DNO – has began manufacturing from the Fenja area within the Norwegian Sea.
Neptune stated that Fenja was anticipated to provide 35,000 barrels of oil equal per day (boepd, gross), through two oil producers with stress help from one water injector and one gasoline injector.
The event consists of two subsea templates tied again to the Equinor-operated Njord A platform. A 36-kilometer electrically trace-heated (ETH) pipe-in-pipe resolution transports oil from the Fenja area to the platform for processing and transport, the corporate stated in a press release.
Because of the excessive wax content material of Fenja’s oil, the contents of the pipeline have to be warmed as much as a temperature above 28 levels Celsius earlier than beginning the circulate after a shutdown. Throughout regular manufacturing, the temperature within the pipeline is nicely above this temperature. The tie-back to Njord A is the world’s longest ETH subsea manufacturing pipeline, the assertion reads.
“The Fenja improvement is a superb instance of how our business makes use of progressive applied sciences to beat challenges. The ETH pipe-in-pipe resolution is essential for transporting the oil and is a artistic, cost-effective method that allows the sphere to be tied again to current infrastructure. Fenja can be situated in a strategically vital development space for Neptune Vitality, with a number of different attention-grabbing prospects close by,” Neptune Vitality’s Managing Director in Norway and the UK Odin Estensen said.
In response to Neptune, complete reserves are estimated between 50 and 75 million boe, 75 p.c of which is oil and 25 p.c is gasoline.
“The ETH pipeline represents an vital technological step, made doable via glorious collaboration between TechnipFMC and Neptune Vitality. It might additionally unlock alternatives to develop future tieback developments,” Neptune’s Initiatives and Engineering Director in Norway Erik Oppedal added.
As for the sphere, Fenja is a subsea improvement within the Norwegian Sea some 74.5 miles north of Kristiansund at a water depth of 1,066 ft. It was found in 2014 and the PDO was permitted in April 2018.
In 2019, set up of the subsea infrastructure began with the set up of templates, manifolds, and umbilical in addition to water and gasoline injection pipelines. In 2020, the primary 9 kilometers of the electrically trace-heated pipe-in-pipe manufacturing pipeline have been put in. The remaining 27 kilometers have been put in in the course of the summer season of 2021. Manufacturing from the Fenja area is anticipated to final for 15 years.
Neptune Vitality is the operator of Fenja with a 30 p.c stake. Its companions are Vår Energi, Sval Energi, and DNO with 45, 17.5, and seven.5 p.c, respectively.
