The Norwegian Petroleum Directorate has issued consent for start-up of the Dvalin field in the Norwegian Sea.

Operator Wintershall DEA estimates that it can recover 18 billion m3 of gas from Dvalin.

The operator's investment projection for the development is approximately NOK 11 billion. Wintershall DEA expects to start up in November/December.

The field is located in production licence PL435. It consists of two structures situated 3.5 km apart. Dvalin øst was proven in 2010 and Dvalin vest in 2012.

The wellstream from Dvalin will be sent to the Heidrun field, which is located south-east of Dvalin, for further processing and export. The gas will be exported via the Polarled pipeline into Nyhamna in Central Norway. The condensate will be routed to the existing process plant on Heidrun and onward via the Heidrun storage ship to tankers for further transport to an oil refinery.

"The development of Dvalin is a textbook example of good utilisation of existing infrastructure in the area", said Tove Francke, Assistant Director for Development and Operations in the Norwegian Petroleum Directorate.

Dvalin was planned as a development with four vertical production wells, two for the eastern part and two for the western part of the field. Drilling and completion of the four production wells started in August 2019 and is now complete.
