Wintershall is set to start production from its flagship project Maria in the Norwegian Sea during the first half of next year.

The company started drilling of the six wells on the field in March, with top holes already complete and drilling towards the reservoir section currently progressing. 

Wintershall CEO Mario Mehren said: “With the drilling of the reservoir, we will be passing another critical milestone that moves us a step closer to first oil.  

“Wintershall believes in Norway. We have invested heavily in the country and are now developing a field that will continue to return value to Wintershall and Norway for many years to come.” 

Maria reservoir is in the Haltenbanken area of the Norwegian Sea and will be linked to three existing platforms through a subsea tieback. 

Under the development plan, the Maria well-stream will be delivered to the Kristin platform for processing.

"We have invested heavily in the country and are now developing a field that will continue to return value to Wintershall and Norway for many years to come."

Water supply for injection into the reservoir will be delivered from Heidrun platform and lift gas will be provided from Åsgard B field. Processed oil will be shipped to the field for storage and exported through the Åsgard transport system to Kårstø. 

Installation of nearly 68km of pipelines and two subsea templates have been completed, while remaining work is expected to be completed by the end of this year. 

The development of this field is expected to involve nearly Nkr15.3bn ($1.7bn) investment. Its recoverable reserves are estimated to be 180 million barrels of oil equivalent. 

Wintershall Norge owns a 50% stake in the licence along with Petoro (30% interest) and Centrica Resources (20% stake).
