OSLO, Norway – Wintershall Norge has discovered oil in the Skarfjell prospect in the northeastern Norwegian North Sea.
The 35/9-7 well was the first drilled in production license 418, awarded under Norway’s APA 2006 licensing round.
It was drilled by the Songa Delta in 368 m (1,207 ft) of water, around 17 km (10.6 mi) southwest of the GDF Suez-operated Gjøa field. The location is between Wintershall’s Grosbeak discovery in PL378 to the south and the Titan discovery in PL420 to the north.
According to partner Agora Oil & Gas, the well encountered a good-quality upper Jurassic reservoir sandstone in the Heather formation containing light oil over a 168-m (551-ft) gross interval.
No fluid contact was observed, and downdip appraisal will be needed to establish the height of the oil column in the Skarfjell structure. The well was not tested, although extensive data acquisition and sampling were performed.
Early estimates suggest 60-160 MMbbl of oil recoverable oil. A new 3D seismic acquisition survey already is under way.
The partners will now focus on integrating well and seismic data to plan the required appraisal program.
The well will be permanently P&A’d. Songa Delta will then transfer to license 375 B to drill appraisal well 33/6-3 S for Suncor Energy Norge.
