OSLO, Norway – Equinor and its partners in Troll Nord in the North Sea can start up facilities and modifications associated with the NOK8-billion ($933-million) Troll Phase 3 project, according to the Norwegian Petroleum Directorate (NPD).
The plan for development and operation, approved in December 2018, involves producing the gas from Troll Vest via two subsea templates with eight gas wells producing to the Troll A platform through a new 36-in. pipeline.
Following further compression, the gas will be exported via existing infrastructure.

The NPD estimates recoverable reserves from Troll Phase 3, mainly gas, at around 2.2 Bboe, with an estimated production lifespan of at least 30 years.
Start-up was originally targeted for spring 2021, but has been postponed until the fall as a result of COVID-19 restrictions.
Troll itself has been in production since 1995, with gas processed at Norway’s Kollsnes terminal. The field came onstream in 1995.
Troll Vest’s oil is produced from wells connected to multiple subsea templates tied via pipeline to the Troll B and Troll C platforms.
