Increasing capacity on Johan Sverdrup to half a million barrels of oil per day
Once again, the Johan Sverdrup field is increasing its daily production capacity, expecting to reach around 500,000 barrels of oil per day by the end of the year – around 60,000 barrels more than the original basis when the field came on stream.
Equinor and its partners have tested the plant capacity in November to verify a possible production rise. As the test results have been very positive a production increase is called for by the end of 2020.
By then the production capacity will rise from today’s 470,000 to around 500,000 barrels of oil per day. The Johan Sverdrup field has had safe and stable operation since it came on stream just over a year ago.
“For the second time since the start-up the plant is able to increase its daily capacity. As Johan Sverdrup is a field with high profitability and low CO2 emissions, a production rise is great news. The field has low operating costs, providing revenue for the companies and Norwegian society, even in periods with low prices,” says Jez Averty, senior vice president for operations south in Development and Production Norway.
The Johan Sverdrup field is powered from shore with very low CO2 emissions per barrel. Emissions during the field life are estimated at less than 0.7kg CO2 per produced barrel.
Phase 2 of the Johan Sverdrup field development is on schedule, and production start is scheduled for the fourth quarter of 2022. The increase means that the Johan Sverdrup full-field plateau production capacity is expected to rise from 690,000 to around 720,000 barrels of oil per day.
The Johan Sverdrup field is using water injection to secure high recovery of reserves and maintain production at a high level.
“Based on the positive results of the capacity test where we produced at rates of over 500,000 barrels of oil per day, we are now working on solutions to increase the water injection capacity which should allow us to further increase daily production capacity beyond this level by mid-2021,” says Rune Nedregaard, vice president for Johan Sverdrup operations.

Facts about Johan Sverdrup
- Johan Sverdrup is the third largest oil field on the Norwegian continental shelf, with expected resources of 2.7 billion barrels of oil equivalent. The ambition for the field is to achieve a recovery rate of more than 70 percent.
- Break even for the full field development is below USD 20 per barrel. Expected operating costs at plateau is below USD 2 per barrel.
- In the first year on stream Johan Sverdrup has produced oil worth around NOK 50 billion, i.e. around 130 million barrels of oil (based on an average price of USD 40 per boe).
- One barrel of oil produced at Johan Sverdrup during the first year has emitted 0.17kg CO2 – almost 100 times lower than the global average (measured in kilogrammes of CO2 per barrel produced). This is mainly due to the power supply from shore.
- The Johan Sverdrup field came on stream on 5 October 2019 – more than two months ahead of schedule and with investment costs that were NOK 40 billion lower than the original estimate in the plan for development and operation (PDO).
- Johan Sverdrup phase 2 includes the construction of a subsea production system, reconstruction of the existing riser platform and a new processing platform (P2).
- Phase 2 will also accommodate a converter plant for shore-based power supply. The plant will distribute power to other fields on the Utsira High: Edvard Grieg, Ivar Aasen, Gina Krog and Sleipner. The four existing platforms on the Johan Sverdrup field are already receiving power from shore.
- Production start is expected in the fourth quarter of 2022.
