Wintershall Dea submits plan for second phase of Maria Field
Wintershall Dea and its partners, Sval Energi and Petoro, will invest around €400 million (NOK 4 billion) to further develop the Maria field in the Norwegian Sea.
On 15 November Michael Zechner, Managing Director of Wintershall Dea Norge, delivered an updated Plan for Development and Operation (PDO) to Terje Aasland, the Norwegian Minister of Petroleum and Energy.
Zechner said: “The Maria Phase 2 project is a major undertaking that will enable us to extract further significant volumes from the field. This investment in Maria shows that we are determined to use our expertise as a subsea operator to generate value from our assets and secure European energy supply.”
The Maria Phase 2 project involves installation of a new six-slot template in the southern part of the field. The template will accommodate two producing wells and one water injector for pressure support. The three spare slots will be available for future development of the field, located about 200 kilometres off the coast of Norway. Maria came on stream in 2017. This next phase of the Maria project is expected to add around 22 million barrels of oil equivalent to the total field reserves. Expected lifetime of the Maria field is 2040.
The new template taps into infrastructure that was already developed as part of the original two-template Maria field. The Maria well stream goes to the Kristin platform. Water injection comes from Heidrun, while lift gas is provided from Åsgard B via the Tyrihans subsea field. Processed oil is sent to the Åsgard field for storage and export. Gas is exported via the Åsgard Transport System to Kårstø.
Wintershall Dea already brought the Nova field into production in July of this year, making the company operator of three producing subsea fields in Norway. The company also expects to bring its fourth subsea field, Dvalin, into production around the turn of the year and plans to deliver another PDO this year for the new Dvalin North field in the Norwegian Sea. These developments showcase Wintershall Dea’s strategy to explore in mature areas, close to existing infrastructure, opening possibilities for efficient subsea developments with smart tie-back solutions.
Wintershall Dea is operator of the Maria field with a 50% share. Petoro AS has 30% and Sval Energi AS owns 20%.
