Latest Alta wells confirm extensive Barents Sea structure

Offshore staff

STOCKHOLM, Sweden – The semisubmersible Island Innovator has completed two appraisal wells for Lundin Norway on the eastern flank of the Alta discovery in the southern Norwegian Barents Sea.

Wells 7220/11-3 and 7220/11-3 A were drilled 4 km (2.5 mi) south of the discovery well in license PL609 and 3 km (1.9 mi) northeast of the previous appraisal well. The location is in 400 m (1,312 ft) of water, roughly 160 km (99 mi) offshore northern Norway.

The first of the two latest wells (7220/11-3) intersected a 120-m (393-ft) thick hydrocarbon-bearing interval, of which 45 m (147 ft) is oil, in good-quality reservoir rocks.

A side track (7220/11-3 A) 400 m to the southeast encountered a gross hydrocarbon column of 74 m (243 ft), of which 30 m (98 ft) was gas and 44 m (144 ft) of oil in reservoir rocks of varying quality. This well will be temporarily P&A’d.

Lundin did not issue an update of its original reserves estimate for the Alta discovery of 125-400 MMboe.

Alex Schneiter, COO of Lundin Petroleum, said: “I am very pleased that all three Alta wells and the two side tracks have proven moveable gas and oil. More importantly we have established good pressure communication between all wells indicating a connected hydrocarbon accumulation over an extensive area.

“We will likely drill up to two further appraisal wells in 2016 in addition to re-entering the latest appraisal well to perform a production test. The Island Innovator rig will now move to the north of PL609 to drill the Neiden prospect.”
