Wintershall boosted its recoverable resources estimate for the offshore Norway Maria field Thursday by 40 million barrels of oil equivalent.
Germany-based Wintershall now estimates technically recoverable resources at Maria will reach about 180 million boe.
Previous estimates placed recoverable reserves at 140 million boe, with oil accounting for 130 million barrels and associated gas production accounting for about 10 million boe.
The new technical production profile is made up of about 150 million barrels of oil, 10 million boe of gas and 20 million boe of natural gas liquids.
Wintershall plans to submit its development and operation plan for the field to Norwegian authorities in the first half of 2015.
Maria is located in a mature area of the Norwegian Sea, about 12 miles east of the Kristin field and about 28 miles south of the Heidrun field.
The Maria reservoir will be linked via a subsea tieback to the Kristin, Heidrun and Åsgard B production platforms through two templates located on the ocean floor.
“It is through own discoveries like Maria that we’re looking to grow in Norway in future, which is why we’re working closely together with our licence partners and regional partners to get these discoveries moved to the production phase as quickly as possible,” Wintershall Norge managing director Bernd Schrimpf said.
Maria is scheduled to start production in 2018 and is Wintershall’s first operated discovery in Norway to be moved into development and production.
Wintershall holds a 50 percent operating stake in the Maria field.
Norway’s Petoro holds a 30 percent share and UK-based Centrica Resources holds a 20 percent.
