Equinor and its partners have been granted a 10-year extension from Norwegian authorities for Troll B facility in Troll field in the North Sea until 2030.
The extended lifetime also includes the oil and gas pipelines that were included in the approved plan for development and operation. The current consent expires in September this year. Since Troll B start-up in September 1995, the facility has produced more than one billion bbl of oil (OGJ Online, Oct. 16, 1995).
Extension of Troll B’s lifetime is one potential solution for further developing gas production from the Troll West gas cap, Troll Phase 3.
Nine seismic surveys have been carried out on the Troll field, with the last one completed in summer 2019. All previous surveys have contributed to identify new well targets. The licensees expect the results from processing the data from the latest seismic survey will yield additional well targets which can be drilled from the subsea templates tied to Troll B.
