Early start for the Maria field
18 des 2017

Spirit Energy’s partner-operated Maria field has started production one year ahead of schedule and more than 20% cheaper than planned. Oil production began on December 16, whereas the original start-up was intended for the fourth quarter of 2018.

At an expected final investment cost of around 12 billion NOK (approximately £1.09 billion), more than 3 billion NOK has been shaved off the original budget.

Dag Omre, Managing director of Spirit Energy Norway, said: “This is a great achievement, particularly from operator Wintershall but also our Maria team that has influenced the project in a way an active partner should do.”

The Plan for Development and Operation (PDO) for Maria was submitted to the Norwegian Ministry of Petroleum and Energy in April 2015.

Mr. Omre said: “Delivering production start-up a short time after investment approval for such a complex offshore project is impressive, and it’s done while maintaining a great safety record.” 

Complex project

The subsea Maria field in the Haltenbanken area of the Norwegian Sea is connected via a subsea tieback to the Statoil-operated Kristin, Heidrun and Åsgard B production platforms, making it a complex underwater project. By tying into local infrastructure and with a planned 25-year life span, Maria could also help prolong the production horizon of surrounding fields.

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 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.

Recoverable reserves of the field are estimated around 180 million barrels of oil equivalent (mmboe), of which the majority is oil. At peak production Maria will add about 8,300 boe/d to Spirit Energy’s production. 

Spirit Energy has a 20% share in the Maria field, while operator Wintershall Norge holds a 50% share. The remaining 30% is owned by Petoro.
