The Dvalin gas field will be a tie-in to the nearby Heidrun platform, creating a development concept aimed at sustainable profitability, the highest safety standards, and tight environmental protection measures. The field is located some 260 kilometres north of Kristiansund in the resource-rich Haltenbanken area of the Norwegian Sea near Wintershall Dea’s Maria field.

Existing infrastructure for sustainable production

The Dvalin field is being developed as a subsea tieback to the Heidrun platform, using an underwater template on the ocean floor. Four wells are being drilled through the template. Flowlines and umbilicals will connect the structure to Heidrun. On the Heidrun platform, a new 4,500-tonne module for processing and compression of gas will be installed. Equinor will perform all work at Heidrun and Wintershall Dea will perform all subsea and subsurface work as Dvalin operator. The gas from Dvalin will be transported to Heidrun via a 14.9-kilometre pipeline. From there, it will be sent to the Polarled trunk line via a 7.5-kilometre pipeline before it will be further processed to dry gas spec at the Nyhamna onshore gas terminal. Finally, the gas will be transported via Gassled to the market.

 

Production in Wintershall Dea core area

The Dvalin field is a satellite of the Heidrun platform in the resource-rich Haltenbanken area of the Norwegian Sea. Wintershall Dea’s Maria field is also located in the area, receiving water injection from Heidrun and services from other nearby fields. Gas from Dvalin will be exported to the Nyhamna gas terminal via the Polarled pipeline.

Dvalin adds to our expertise in subsea development and puts us in the forefront of underwater production in Norway.
