The Dvalin field is located 15 kilometres northwest of the Heidrun field. It consists of two separate structures. The Dvalin East segment was proven in 2010, and the 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.
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 Equinor operated Heidrun platform through a 15 kilometre pipeline. A new 3500 tonne process module is installed at Heidrun as a part of the Dvalin project.
The gas in transported through a new 7.5 kilometre export pipeline, routed into Polarled and further to the Nyhamna gas receiving facility. At Nyhamna, the gas is further processed before being exported as dry gas via Gassled to the market.
