The Johan Sverdrup oil field (Sverdrup Field) is an oil field in the North Sea, about 140 kilometres (87 mi) west of Stavanger, Norway. The field lies in two different production licenses and consists of two different discoveries called Avaldsnes (where Lundin Petroleum is the operator) and Aldous Major South (where Statoil - now known as Equinor - is operator). When it was revealed that these discoveries constituted one single field, it was renamed Johan Sverdrup after the father of Norwegian parliamentarism. The field has not yet been unitized between production licenses 501, 501B, and 265. ^[1] Johan Sverdrup is expected to hold 1.9–3.0 billion barrels (300–480 million cubic metres) of oil.^[2] According to Statoil,^[3] the field is in 110 to 120 metres water depth, and the reservoir is at 1900 meters depth.

Field development

In March 2012, after a signing of a pre-unit agreement between the different licensees, Statoil was appointed working operator. Production startup is expected in 2019.^[4] Peak production is estimated to be over 500,000 barrels per day (79,000 m³/d), which will make it by far the largest producing oil field in the North Sea by the time it reaches its peak. The oil produced at the field will be transported by pipelines to the Mongstad refinery where it will be shipped and refined.

The first stage of development Phase 1 will consist of four-platform field hub producing 440,000 barrels per day after startup in late 2019. Its front-end engineering and design work was awarded to Aker Solutions, who were also awarded the contract for the detailed engineering phase in January 2015.^[5] The platform jacket work for 3 Platforms (P1, DP and RP) was awarded to Kværner built in Verdal Yard near Trondheim. Dragados was awarded the contract for the LQ jacket to be built in Spain. ^[5]

The field development includes high-voltage direct current (HVDC) link that will supply the Johan Sverdrup offshore oilfield development with electricity from the onshore grid. Supplying power from shore to run the oil platforms, instead of using local generation, considerably lowers CO2 emissions.

ABB will design, engineer, supply and commission the equipment for two ±80 kilovolt 100 MW HVDC converter stations, using Voltage-Sourced Converters (VSC) technology.

The project includes installation, supervision and site services. One station will be situated on-shore at Haugsneset, near the Statoil Kårstø plant on the Norwegian west coast, the other on the platform situated 155 km west of the Norwegian coastline. Further studies will examine if HVDC power can be fed to other platforns in nearby fields.

Phase 2 will be for a fifth Platform P2 capable of processing 220,000 barrels per day. This contract was awarded to Aibel to be built in their yard in Haugesund, Norway.

On February 13, 2015 Statoil announced it will proceed to develop the Johan Sverdrup field despite disagreements over ownership stakes with fellow Norwegian upstream AkerBP.^[6]
