“We have given Statoil consent to use the Songa Encourage mobile drilling facility to drill and complete production well 31/2-O-24 on the Troll field,” says the PSA.
The well will be drilled in a well template tied back to Troll C by a subsea pipeline. Water depth at the site is 338m. The drilling work is scheduled to take 71 days.
The Troll field is in the North Sea, around 65km west of Kollsnes in Hordaland county. The field has been developed using three integrated process and accommodation facilities, Troll A, B and C, and subsea well templates tied back to the B and C facilities.
Troll contains around 40% of the total gas reserves on the Norwegian Continental Shelf, but is also among the largest oil fields on the shelf.
The Songa Encourage is operated by Songa Offshore. It was built at the Daewoo yard in South Korea in 2016. It is classified by DNV GL and registered in Norway.
