Wintershall Dea has demobilised the rig West Hercules after completing earlier than expected a controversial wildcat at the Toutatis prospect off Norway’s Lofoten Islands, apparently without success.

It can be confirmed by Upstream that the German operator has decided not to exercise an option for a sidetrack at the 6611/1-1 well in its operated production licence 896, about eight kilometres south of the eco-sensitive Traena coral reef, potentially indicating no hydrocarbons have been found.
