Wintershall Scores Skarfjell Appraisal Well Success
Wintershall reported late Tuesday that its appraisal well 35/9-8 on the Skarfjell oil discovery has found a 210-foot oil column. The column, discovered in the Heather formation, is estimated to contain between 73 million and 183 million barrels of oil.
The Skarfjell discovery is located in the Norwegian North Sea on production license 418, where Wintershall Norge is the operator. Appraisal well 35/9-8 is located just over a mile north of the 35/9-7 discovery well.
Wintershall said that the appraisal well has encountered the location of oil/water contact and that a successful formation test was completed. The maximum production rate from a 43-foot section of the reservoir was 2,200 barrels of oil and 1.9 million cubic feet of gas per day through a 24/64-inch choke.
Cairn Energy, one of Wintershall's partners in Skarfjell, said that it has revised its gross resource range for the discovery to between 74 million barrels and 235 million barrels. Cairn holds a 20-percent interest in the license, while Wintershall as operator has a 35-percent interest.
Cairn Energy Chief Executive Simon Thomson commented in a statement:
"Skarfjell is one of the largest discoveries in the Norwegian Sector of the North Sea in recent years. The combination of very good reservoir and large volumes will allow this discovery to be progressed towards development, with a number of commercially attractive options possible including a standalone facility or a hub development incorporating surrounding undeveloped discoveries."
The Skarfjell appraisal well was drilled by the Transocean Arctic (mid-water semisub) rig, which will now proceed to production license 511 in the Norwegian Sea to drill wildcat well 6406/6-3, where Wintershall Norge is the operator.
