German gas and oil producer Wintershall Dea has won a consent to begin operations at the Dvalin field in the Norwegian Sea.

The field is located nearly 260km north of Kristiansund in the resource-rich Haltenbanken area of the Norwegian Sea.

Wintershall Dea expects to start up the field in November/December and recover 18 billion standard cubic metres of gas from it.

The company is the operator of the field that is located in production license PL435.  Petoro and Edison Norge are its partners in the license.

The field consists of two structures Dvalin øst and Dvalin vest, which are located 3.5km apart.

Dvalin øst and Dvalin vest reservoirs, which lie at a depth of 4,500 metres, were proven in 2010 and 2012, respectively.

According to Wintershall Dea estimates, the investment for the development of Dvalin field is NOK11bn ($1.19bn).

The development concept for the field is a subsea template with four production wells tied-back to the Heidrun platform.

“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.

The planned development of the field included drilling of four vertical production wells, which are now complete.

Two wells have been drilled in the eastern part of the field, while the other two on the western part of it.

The Heidrun field, which is located south-east of Dvalin, will receive the wellstream from Dvalin for further processing and export.

Later, the gas will be transported through the Polarled pipeline into Nyhamna in Central Norway.

The Dvalin field is located near Wintershall Dea’s Maria field in the Norwegian Sea.
