[Norway] Johan Castberg

The Johan Castberg (formerly Skrugard) field is situated approximately 100 kilometres north of the Snøhvit-field in the Barents Sea.

The Johan Castberg field development project’s resource base consists of the three oil discoveries Skrugard, Havis and Drivis, located in PL 532. The field is expected to come on stream in 2023 and will produce for 30 years.

To achieve profitability in the project after the fall in the oil price in 2014-15, Equinor and the partners had to change the design concept and develop new solutions in order to be able to carry out the development.

DEVELOPMENT SOLUTION

The field will be developed with an FPSO+ production vessel with additional subsea solutions. Compared with the original solution, costs have been reduced from approximately 100 billion NOK to 50 billion. At sea level, the FPSO will be visible—but it is underwater that the true size of the field is seen. Castberg is a large subsea field and is key to the possible further development and infrastructure in the Barents Sea.

Johan Castberg is a breakthrough in unexplored areas where we must interact with other interests, such as the fisheries. At the same time, this is a development which will have ripple effects including an impact on technology and expertise building in the supplier industry—particularly in the north.
  • The Equinor-operated discoveries Skrugard from 2011, Havis from 2012 and Drivis from 2014 comprise what is now the Johan Castberg project.
  • The proven volumes in Johan Castberg are estimated at between 400 and 650 million barrels of oil
  • Location: Situated approx. 100 kilometres north of the Snøhvit-field in the Barents Sea in blocks 7219/9 and 7220/4,5,7, about 100 km north of the Snøhvit field, 150 km from Goliat and nearly 240 km from Melkøya. The water depth is 360-390 meters, 7 km between Skrugard and Havis
  • The discoveries: Skrugard April 2011, Havis January 2012, Drivis May 2014

At over 300 metres long, 120 metres tall and with a bright orange hull, the Johan Castberg FPSO has been quite a visible sight quayside at Aker Solutions’ Stord yard the last two years.

On 30 May the FPSO left for sea trials in Klosterfjorden, before it heads home to the Barents Sea towards the end of summer.

The Johan Castberg field is located approx. 100 kilometres north of the Snøhvit field in the Barents Sea. The resource base for developing the Johan Castberg field consists of the three oil discoveries Skrugard, Havis and Drivis, all of which are located in production licence 532. The field is scheduled to start up in Q4 2024, and will produce for 30 years. The expected recoverable resources are estimated at 450—650 million barrels of oil equivalent.

The field development concept includes a production vessel and an extensive subsea development, with a total of 30 wells distributed across 10 subsea templates and two satellite structures. Operations of Johan Castberg will be handled using a supply and helicopter base in Hammerfest and an operating organisation in Harstad.

Johan Castberg anchored on the field

17 September 2024

The floating production, storage and offloading vessel (FPSO) is now securely anchored on the Johan Castberg field in the Barents Sea.

The hook-up of the FPSO to the subsea facilities, preparing it for production start-up towards the end of the year, will now start.

"This is an important milestone for Equinor and its partners Vår Energi and Petoro.Johan Castberg strengthens Norway's role as a reliable, long-term energy supplier. The field will create great value for society, and long-term ripple effects and jobs. I would like to thank everyone who has contributed," says Trond Bokn, Equinor's senior vice president Project development.

Johan Castberg is a large oil field with estimated recoverable volumes of between 450 and 650 million barrels. The field will produce for 30 years, and at its peak, Johan Castberg may produce 220,000 barrels per day. The field development concept includes 30 wells distributed across ten subsea templates and two satellites that will now be tied back to the FPSO. So far, 13 of these wells have been drilled, and drilling operations will continue into 2026.

Johan Castberg is located 240 kilometres northwest of Hammerfest. The field has a supply and helicopter base in Hammerfest and an operations organisation in Harstad.

"Johan Castberg is important for our development plans in Northern Norway. When the field comes on stream, a new province will be opened for oil recovery in the Barents Sea. This provides new opportunities for the exploration for and development of new discoveries in the area. Working with our partners we are already maturing five discoveries towards a possible tie-in to Johan Castberg," says Grete Birgitte Haaland, Equinor's senior vice president for Exploration & Production North.

The Norwegian supply industry has accounted for more than 70 percent of the total deliveries to the Johan Castberg project. In the operating phase, 95 percent of deliveries are expected to come from Norwegian suppliers. The North Norwegian content is estimated at about 40 percent, and every third Johan Castberg employee lives in Northern Norway.
