Equinor and partners have submitted the development and operation plan (PDO) for Phase 3 of giant Troll oil and gas field in the Norwegian North Sea.
The phase will produce from the gas cap of the Troll West structure, which produces oil under Phase 2 development involving the Troll B and C platforms.
Equinor in May exercised an option for delivery of a processing module for the Troll A platform, subject to filing of the PDO with the Ministry of Petroleum and Energy and a final investment decision (OGJ Online, May 16, 2018). Troll A was installed during the first development phase to handle gas produced from the Troll East structure.
Troll field has produced 33 billion boe of oil and gas since production began in 1995. The Norwegian Petroleum Directorate estimates remaining reserves at 38 billion boe.
Third-phase development will include the installation of two subsea templates and drilling of eight production wells tied back to the Troll A platform with a 36-in. pipeline.
Equinor, operator, holds a 30.58% interest. Other interests are Petoro, 56%; Norske Shell, 8.10%; Total E&P Norge, 3.69%; and ConocoPhillips Scandinavia, 1.62%.
