The field has 2 structures - Troll east and Troll west.
Troll is a significant supplier of gas to the European market and can meet 7-8% of Europe's total daily gas consumption.
It is Europe's biggest producing field, and after more than 20 years of production still has 65% of the gas to be recovered.
The field covers approximately 700 km².
It is jointly owned by:
- Norway's Petoro (56%)
- Equinor (30.58%, operator)
- Shell (8.1%)
- TotalEnergies (3.69%)
- ConocoPhillips (1.62%)
Phase 2 recovered oil from the Troll west structure.
The 1st 2 phases have together recovered more than 900 million m3 of oil & gas and are expected to continue producing until 2060.
Phase 3 of the Troll field will focus on the recovery of gas from the Troll west structure.
Production from phase 3 is scheduled to begin in 2021.
Recoverable volumes from Troll Phase 3, which will produce the Troll West gas cap located above the oil column, are estimated at as much as 347 Bcm of gas.
Investment in the project was $923 million.
