The Dvalin field is located 15 km northwest of the Heidrun field. It consists of two separate structures. Dvalin East segment was proven in 2010, and Dvalin West segment was proven in 2012. The final investment decision was made in 2016 and the PDO was approved in June 2017. The reservoir contains gas in Middle Jurassic sandstone in the Ile and Garn Formations.
The Dvalin field development is a conventional subsea tie-back to the Heidrun TLP. The development concept is a subsea 4-slot template with four production wells, two into Dvalin East and two into Dvalin West. The subsea template is tied- back to the Equinor operated Heidrun platform through a 15 km pipe-in-pipe (12”/16”) flowline. A new 3500 tonnes process module is installed at Heidrun as part of the Dvalin project.
The gas is transported through a new 7.5 km export pipeline, routed into Polarled and further to Nyhamna gas receiving facility. At Nyhamna, the gas is further processed before being exported as dry gas via Gassled to the market.
