OSLO, Norway -- BG Norge has found further oil close to its Knarr field in the northern Norwegian North Sea.
The semisub West Alpha drilled two wells to the west of Knarr (ex-Jordbær) in production license 373 S. According to the Norwegian Petroleum Directorate, (NPD) both proved oil in early Jurassic sandstones. Wildcat well 34/3-3 S found oil in the upper part of the Cook formation with good reservoir quality. Water depth was 400 m (1,312 ft).
The purpose of subsequent side track 34/3-3A was to confirm the extent of the reservoir rocks and to look for oil in the lower part of the Cook formation. It proved oil in both the upper and lower Cook formation, again with good reservoir quality.
Well 34/3-3 S was also production-tested, flowing 1,200 cu m/d (7,548 b/d) of oil through a 12.7-mm (5 in) choke. It will be temporarily plugged for potential use in a future production scheme.
NPD estimates in-place reserves in the range 1.5-4 MMcmoe (9.4-25.2 MMboe), which could be produced through theKnarr production ship. Norway’s parliament approved development of the Knarr field last June.
Well 34/3-3 S will now be temporarily plugged for potential use in a future development.
West Alpha now heads to PL 435 in the Norwegian Sea to drill delineation well 6507/7-15 for RWE Dea Norge.
NPD has also authorized Statoil Petroleum’s use of the semisub Aker Barents to drill an appraisal well (7220/5-1) in the Barents Sea. The location is around 100 km (62 mi) northwest of the Snøhvit field and 3 km (1.8 mi) north of discovery well 7220/8-1.
This will be the third well on license 532.
