North Sea

Germany-based crude oil and natural gas producer Wintershall has completed drilling of Asha Noor appraisal wells and discovered oil in the central part of the Norwegian North Sea, about 200km off the coast of Stavanger.

The company drilled two Asha Noor appraisal wells, 16/1-16 and its delineation 16/1-16 A in production licence PL 457, about three kilometres east of the 16/1-9 discovery well in the Ivar Aasen discovery and about three kilometres north of the Edvard Grieg field.

Wintershall spud 16/1-16 to a vertical depth of 2,722m and 16/1-16 A to 2,683m below mean sea level and terminated the wells in the Permian Rotliegendes and the Triassic Skagerrak Formation.

Preliminary estimates indicate about 20 million to 40 million barrels of recoverable oil.

The company performed extensive coring, sampling and data acquisition and the results will be evaluated to further determine the commercial potential of the discovery.

"Preliminary estimates indicate about 20 million to 40 million barrels of recoverable oil."

Wintershall Exploration and Production board member Martin Bachmann said that Asha Noor is the company’s third oil discovery in Norway during the past 12 months.

"After our discoveries with the Maria appraisal well and Skarfjell, the Asha Noor discovery provides further confirmation that the Utsira High region offers considerable potential," Bachmann added.

The firm has plans to increase its daily production in the Norwegian continental shelf from 4,000 to 50,000 barrels of oil equivalent by 2015. Asha Noor is the first well drilled by the company in production licence PL 457, awarded in the APA 2007.

Wintershall Norge is the operator of the well with 40% interest, while other participating companies are E.ON E&P Norge, Bridge Energy Norge and VNG Norge, each holding 20% interest.
