About the field
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
- Development
- Dvalin is a field in the central part of the Norwegian Sea, 15 kilometres northwest of the Heidrun field. It consists of three separate deposits: Dvalin East, West and North that were proven in 2010, 2012 and 2021, respectively. The water depth is between 340 and 400 metres. The plan for development and production (PDO) of the East and West deposits was approved in 2017. The development concept is a subsea template with four production wells tied-back to the Heidrun platform. The production started in 2020. A PDO for Dvalin North was approved in 2023, and includes a subsea template with three production wells.
- Reservoir
- Dvalin contains gas in Middle Jurassic sandstone in the Ile and Garn Formations. The reservoirs are at a depth of 4500 metres and have high pressure and high temperature (HPHT). The homogeneous shallow marine Garn sandstone has good reservoir quality, while the more heterogeneous and fine-grained Ile sandstone has less favourable reservoir properties.
- Recovery strategy
- The field is produced by pressure depletion.
- Transport
- The well stream is transported via pipeline to Heidrun for processing at a dedicated gas processing module. The gas is exported via Polarled to Nyhamna and then via Gassled to the market.
- Status
- The production from Dvalin is stable on plateau.
