Statoil has made a gas discovery in the Gymir prospect, the third find the Aasta Hansteen area for the company and its PL602 partners.
The Norwegian explorer estimates the volumes in Gymir to be in the range of between six and 19 milion barrels of oil equivalent.
Well 6706/11-2 was drilled by the Transocean Spitsbergen rig in the Gymir prospect and proved a gross 70-metre gas column in the Nise formation.
Gymir is located just eight kilometres away from Roald Rygg and 14 kilometres away from Snefrid Nord.
Dan Tuppen, vice president of exploration in Norway and the Barents Sea for Statoil, said: “Our 2015 exploration campaign around Aasta Hansteen has proven an upside potential in the area.
“The estimated total volumes in the three discoveries, Snefrid Nord, Roald Rygg and Gymir, amount to 75-120 million barrels of recoverable oil equivalent, corresponding to about 1/3 of the Aasta Hansteen recoverable volumes.
“The discoveries will now be further evaluated for future tie-in to the Aasta Hansteen facilities in order to optimise utilisation of the infrastructure and prolong the production plateau.”
Aasta Hansteen will be the largest SPAR platform in the world and is the biggest ongoing field development project in the Norwegian Sea.
It is one of the main project’s in Statoil’s portfolio, with production start-up expected in 2017.
The drilling in all three wells, Statoil said, have been “extremely efficient” – making them the fastest deepwater wells ever drilled on the Norwegian continental shelf.
