Equinor and its license partners have secured the Norwegian Petroleum Directorate (NPD) approval to commission the Troll phase 3 project in the North Sea.
Troll phase 3 is a further development of the Troll field, which is located 60km west of Sognefjorden in the Norwegian North Sea, at a water depth of 300m.
The development and operation plan (PDO) for Troll phase 3 was approved in December 2018. It will produce gas from Troll Vest.
The project partners have selected a development solution that comprises two subsea templates with eight gas wells tied into the Troll A platform.
For further compression and export through existing infrastructure, the wellstream from the tied wells is routed to Troll A through a new 36-inch pipeline.
The companies have invested more than NOK8bn (US$932m) in Troll phase 3, with a plan approved for it to produce for at least 30 years.
The Troll phase 3 project is estimated to have recoverable reserves of nearly 2.2 billion barrels of oil equivalent, primarily comprised of gas.
