Field: Heidrun and Dvalin
Start-up: Q2, 2020
Other info: The development solution/concept for Dvalin is to connect the well stream to Heidrun TLP for processing. Condensate will go to Heidrun B, and gas will be sent via Polarled to Nyhamna.
Dvalin
Dvalin is a field in the central part of the Norwegian Sea, 15 kilometres northwest of the Heidrun field. It consists of three separate structures, Dvalin East (proven in 2010) Dvalin West (proven in 2012) and Dvalin North (proven in 2021). The water depth is between 340 and 400 metres. The plan for development and production (PDO) for Dvalin East and West was approved in March 2017. The development concept is a subsea template with four gas producers tied-back to the Heidrun platform. Production started in 2020.
PDO for Dvalin North was approved in June 2023, and includes a subsea template with three production wells. Dvalin North is under development and is planned to start production in 2026.
