Eni SpA (NYSE: E) expects to restart oil production at its Goliat platform in the Barents Sea off Norway within days after it was shut, a spokesman said on Aug. 28.

The production at Norway's only Arctic oil field was shut Aug. 26 after the platform lost power supply from shore, prompting partial staff evacuation. The supply was restored after several hours, Eni has said.

"It will be a matter of days [before production is resumed]... As a safety precaution we won't resume production until all the facts are gathered," Andreas Wulff, the spokesman for the company in Norway, told Reuters.

Eni is the operator of Goliat with a 65% stake, while Norway's Statoil ASA (NYSE: STO) has the remaining stake in the Arctic Field, which started producing earlier this year after several delays.
