Dvalin is a field in the central part of the Norwegian Sea and consists of two separate structures, Dvalin East and Dvalin West. Dvalin East was proven in 2010 and is located 15 kilometres northwest of the Heidrun field. The water depth is 344 metres. Dvalin West was proven in 2012 and is located 3.5 kilometres west of Dvalin East. The water depth is 400 metres. The plan for development and production (PDO) was approved in March 2017. The development concept is a subsea template with four gas producers tied-back to the Heidrun platform.

The field is currently under development. Production is planned to start in late 2020.
