Wintershall confirms resource estimates with Skarfjell appraisal well

STAVANGER -- Wintershall announced the successful drilling of the Skarfjell appraisal well in the northeastern North Sea, confirming the extension of the reservoir sands found in the field’s discovery well.

The 35/9-8 well was drilled 1.8 km north of the Skarfjell discovery well (35/9-7), and approximately 16 km southwest of the GjØa platform. The purpose of the well was to prove oil in the upper Jurassic intra-Heather sandstone, as found in the discovery well (35/9-7). The field’s volume is estimated at 60-160 million barrels, and the successful production test confirmed the reservoir’s deliverability.

A second appraisal well is being planned in the southern part of the Skarfjell structure with implementation by mid-2014. The Skarfjell discovery will be further evaluated for a development together with other discoveries in the area as a tie back to the GjØa field or as a standalone development. The 35/9-8 well is the second well in production license PL 418, which was awarded in the APA 2006.

The well found a 64-m hydrocarbon column in intra-Heather sandstone with gross thickness and good reservoir quality. The whole reservoir interval was cored and extensive data acquisition and sampling was done. The pressure data shows that the oil column in the appraisal well communicates with the column in the discovery well and the oil-water contact was found in the well.

The well was drilled by the drilling rig Transocean Arctic to a vertical depth of 3,232 m below mean sea level, with a water depth of 368 m. The well will now be permanently plugged and abandoned.

Current partners of the license are Wintershall (operator, 35%), Capricorn (former Agora Oil & Gas, 20%), Bayerngas (20%), Edison International Norway (15%) and RWE (10%). Wintershall, a wholly-owned subsidiary of BASF, is the largest internationally active German crude oil and natural gas producer, and counts the North Sea as one of its traditional core regions.
