OSLO, NorwayDet norske oljeselskap has proven further oil and gas from one of two appraisal wells in the Ivar Aasen area of the central Norwegian North Sea.

The jackupMaersk Interceptor took a break from development drilling at Ivar Aasen to drill wells 16/1-26 S and 16/1-26 A in license 001B, 15 km (9.3 mi) southeast of the 2004 16/1-7 (West Cable) oil discovery well.

Here hydrocarbons were proven in Mid-Jurassic reservoir rocks (the Sleipner formation). Prior to the latest wells Det norske estimated recoverable reserves at 2.1 MMcmoe.

The jackup drilled the two appraisal wells in 113 m (371 ft) of water from a production well that was being drilled from theIvar Aasen platform.

While 16-1-26 A was dry, 16/1-26 S encountered a gas/oil column of about 25 m (82 ft) in Middle Jurassic reservoir rocks (the Hugin formation), of which 15 m (49 ft) were sandstone of moderate to good reservoir quality.

The oil/water contact, although not encountered, was estimated to be at around 2,700 m (8,858 ft) vertical depth, shallower than the level calculated for the original discovery.

TheNorwegian Petroleum Directorate assessed the resources in the range of 0.5-2 MMcmoe recoverable, adding that the resultant data should assist final placement of the development well on the 16/1-7 discovery.

Ivar Aasen is due to come onstream on Dec. 1.
