Equinor Energy AS started production on Aug. 27 from the Troll Phase 3 project in the North Sea.
Phase 3 consists of eight wells in two templates, a new pipeline, and umbilical connecting the templates to Troll A as well as a new gas processing module on the platform (OGJ Online July 2, 2021). Phase 3 involves producing the gas cap overlying the oil column in Troll West, while simultaneously continuing to produce the oil. Produced gas goes to Troll A and onward in existing infrastructure.
The phase is expected to extend the life of Troll A and the Kollsnes processing plant beyond 2050, and the plateau period by 5-7 years, Equinor said. Recoverable volumes from Phase 3 are estimated at as much as 347 billion cu m of gas (2.2 billion boe).
Investment in Phase 3 is about NOK 8 billion. Emissions of CO2 will be less than 0.1 kg/boe based on power supplied from shore.
Equinor is operator at Troll (30.58%) with partners Petoro AS (56%), AS Norske Shell (8.10%), TotalEnergies EP Norge AS (3.69%), and ConocoPhillips Skandinavia AS (1.62%).
