Wintershall Dea and its partners Petoro and Sval Energi have received approval from the Norwegian Ministry of Petroleum and Energy (MPE) for their plans to develop the Dvalin North field and the second phase of the Maria field in the Norwegian Sea.
The Ministry has also approved four developments where Wintershall Dea is partner: Irpa, Solveig Phase 2, Alve Nord, and Idun Nord.
The Dvalin North gas field, which was the largest discovery in Norway in 2021, will be developed as a tieback to the nearby Heidrun platform via the Wintershall Dea-operated Dvalin field.
The three partners said they plan to drill three producing wells from a subsea template located 10 km to the north of the existing Dvalin field.
The field is estimated to contain around 84 million BOE and is planned for startup in late 2026. Wintershall Dea Norge is operator of the field with a 55% share. Petoro owns 35%, and Sval Energi has 10%.
Maria Phase 2 involves the installation of a new six-slot template in the southern part of the Wintershall Dea-operated Maria field. The new template taps into infrastructure that was developed as part of the original two-template Maria field. The MPE has approved plans for two producing wells and one water injector. Three spare slots will be available for future development.
The project is expected to add around 22 million BOE to the total field reserves. The partnership has approved plans to drill an additional producing well, adding another estimated 5 million BOE.
Maria came on stream in 2017 with an expected lifetime until 2040.
