Green light for Troll phase 3 start-up
Licensees in Troll Nord in the North Sea have secured consent to start-up facilities and modifications associated with the Troll phase 3 project.
The plan for development and operation (PDO) for Troll phase 3 was approved in December 2018. The project is a further development of the Troll field and will produce gas from Troll Vest.
The development solution chosen by the operator Equinor and partners comprises two subsea templates with eight gas wells tied into the Troll A platform. The wellstream from these wells is routed to Troll A (pictured) through a new 36-inch pipeline, for further compression and export via existing infrastructure.
Recoverable reserves from Troll phase 3, mainly gas, are estimated at about 2.2bn boe (350mn cm). This latest development will help maintain production from the giant Troll field, which currently supplies up to 7% of Europe’s daily demand for gas. Planned to produce for at least 30 years, Troll phase 3 was originally scheduled to come onstream this spring, but start-up was postponed until the autumn due to the COVID-19 pandemic.
