Wintershall group proves Skarfjell oil find offshore Norway

A Wintershall Norge AS group will drill a second appraisal well on the southern end of Skarfjell oil field in the northeastern North Sea offshore Norway after an appraisal well in the field’s northern reaches confirmed earlier estimated resource range of 60-160 million bbl of oil.

The purpose of the 35/9-8 appraisal well, 16 km southwest of the Gjoa platform was to prove oil in the Upper Jurassic Intra Heather sandstones as found in the Skarfjell 35/9-7 discovery well 1.8 km south. The well confirmed the northern extension, and a production test demonstrated reservoir deliverability, Wintershall said.

The 35/9-8 well, drilled to 3,232 m true vertical depth below mean sea level in 368 m of water, found a 64-m hydrocarbon column in Intra Heather sandstone with gross thickness and good reservoir quality as expected. It also found the oil-water contact. The entire reservoir was cored and extensive data and samples collected. Pressure data show communication with the discovery well.

After drilling the southern appraisal well in mid-2014, the company will evaluate a combined development with other area discoveries as a standalone project or tieback to Gjoa field.

License interests are Wintershall Norge 35%, Capricorn Norge AS (formerly Agora Oil & Gas AS) 20%, Bayerngas Norge AS 20%, Edison International Norway 15%, and RWE Dea Norge AS 10%.
