Development

Dvalin is a field in the central part of the Norwegian Sea, 15 kilometres northwest of the Heidrun field. It consists of two separate structures that are 3.5 kilometres apart. Dvalin East was proven in 2010 and Dvalin West was proven in 2012. The water depth is 340 and 400 metres, respectively. The plan for development and production (PDO) was approved in 2017. The development concept is a subsea template with four production wells tied-back to the Heidrun platform.

Reservoir

Both Dvalin East and Dvalin West contain gas in Middle Jurassic sandstone in the Ile and Garn Formations. The reservoirs lie at a depth of 4,500 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 will be produced by pressure depletion.

Transport

The well stream will be transported to the Heidrun platform for processing in a new dedicated gas processing module and exported to the Nyhamna terminal via a new pipeline from Heidrun to Polarled.

Status

The field is currently under development. A dedicated processing module for Dvalin was installed on the Heidrun platform in 2019. Drilling of the wells started in 2019, and start-up of production is planned for late 2020.
