The semisubmersibleSonga Delta drilled both wells in 107 m (351 ft) of water on production license 035/272, around 6 km (3.7 mi) southeast of the 30/11-8 S (Krafla) discovery and 25 km (15.5 mi) southwest of the Oseberg Sør.
Well 30/11-14 encountered two gas columns at two levels in the upper section of the Tarbert formation, of which 14 and 5 m (46 and 16.4 ft) exhibited good to moderate reservoir properties.
Subsequent well 30/11-14 B penetrated two gas/oil columns and an oil column at three levels in the upper part of the Tarbert formation, of which 18, 9, and 13 m (59, 29.5, and 42.6 ft) have good to moderate reservoir properties.
Early analysis suggests total recoverable reserves in the range of 3-7 MMboe. The licensees will assess the results with regard to a potential development.
The wells were not formation-tested, but extensive data acquisition and sampling have been carried out in both wells.
These were the fifth and sixth exploration wells on the license, awarded under Norway’s 2001 North Sea round.
