COPENHAGEN, Denmark --DONG E&P Norge has proven hydrocarbons with its latest well on the Oselvar field in the southern Norwegian North Sea.

The jack-upMaersk Guardian drilled well 1/3-10 to a depth of 3,288 m (10,787 ft), in early Paleocene sediments. This was the third well on the structure since the discovery by previous operator Elf Petroleum Norge in 1991.

According to DONG's partner Revus Energy, the main aims were to assess reservoir deliverability and to gather fluid samples for characterization purposes via small-scale formation tests.

Reservoir thickness and quality were in line with expectations. The well was also tested, flowing 530 cu m/d of oil/condensate with a gas-oil ratio of 467 cu m/cu m.

The partners now plan to drill a down-flank sidetrack, 1/3-10 A, to establish the oil-water contact, and for water sampling. After plugging and abandoning this well, the rig will pass temporarily to BG Norge before returning to the Oselvar license (PL 274) partners this summer to drill the Ipswich prospect.

Oselvar is situated in 72 m (236 ft) of water, 20 km (12.43 mi) west of the Gyda field.
