Troll Field Sets Norwegian Production Record
January 7, 2025
The Troll field in the North Sea has set a historic production record, delivering 42.5 billion standard cubic meters of natural gas in 2024.
This is the highest annual production ever for the field and an increase of almost 10% from the previous record from 2022 (38.8 billion standard cubic meters).
Troll A and the processing plant at Kollsnes have been electrified since the start-up in 1996. Gas on the Norwegian continental shelf (NCS) is locally sourced and has the industry's lowest emissions from production and transport.
This year's record is the result of high regularity, a year without turnarounds, as well as upgrades that have increased efficiency. Riser replacement on Troll B has also played an important role in maximizing production.
Since coming on stream in 1996, the Troll A platform has been the main contributor to natural gas production on the NCS. In 2021, production was expanded to also include the gas cap in the western part of the reservoir, facilitated by a major subsea development.
This expansion has been instrumental in increasing production, even 28 years after the start-up. The Troll B and C platforms also contribute significant quantities of gas that are transported via Troll A to Kollsnes.
During 2024, both the Troll B and C platforms were partially electrified. This enabled significant CO2 emission cuts for 2024. A preliminary estimate indicates that emissions have been reduced by approximately 90,000 tonnes in 2024, or approximately 15% in 2024.
The gas processing plant at Kollsnes has undergone significant upgrades in recent years. Working closely with the operator Gassco, capacity has been increased from 144.5 million to 156 million standard cubic meters per day. This has been an important contribution to the production record.
Troll is the largest oil and gas field on the NCS, and it accounts for about 11% of the EU's total natural gas consumption. The amount of energy generated by 42.5 billion standard cubic meters of gas is equivalent to about three times the Norwegian hydropower production in a normal year.
Troll licensees are Equinor, Petoro, Norske Shell, TotalEnergies and ConocoPhillips.
