Plan for Development and Operation for Maria approved

Wintershall and its partners Petoro and Centrica have received approval by the Ministry of Petroleum and Energy for the plan for development and operation (PDO) for the Maria development, offshore Norway.


Under the approved development solution, the Maria reservoir will be linked via a subsea tieback to the Kristin, Heidrun and Åsgard B production platforms. The Maria well stream will go to the Kristin platform for processing, while supply of water for injection into the reservoir will come from the Heidrun platform and lift gas will be provided from Åsgard B via the Tyrihans D field subsea template. Processed oil will be shipped to the Åsgard field for storage and offloading to shuttle tankers. Gas will be exported via the Åsgard Transport System to Kårstø.

Investments in the Maria development are estimated at around NOK 15.3B (100%), including development drilling. Recoverable reserves on the field are estimated around 180 million barrels of oil equivalent (boe), of which the majority is oil.

The Maria field is located approximately 20 kilometres east of the Kristin field and about 45 kilometres south of the Heidrun field in the Halten Terrace in the Norwegian Sea.
