Johan Castberg

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.

Development solution

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.

The production vessel will be a so-called FPSO+ with subsea solutions. The expected recoverable resources are estimated at 450—650 million barrels of oil equivalent.

On the sea surface, you will see an anchored production vessel, a so-called FPSO. But it is underwater that the real size of the field presents itself. Johan Castberg is a major subsea field and is important for potential further development and infrastructure in the Barents Sea.

Operations of Johan Castberg will be handled using a supply and helicopter base in Hammerfest and an operating organisation in Harstad. Estimated investments to operate the field come to around NOK 1.15 billion annually. This will generate around 1,700 person-years of employment nationally, around 500 of which will be in Northern Norway. This includes both the direct and indirect effects.

A study conducted by Kunnskapsparken Bodø and Agenda Kaupang shows that the regional value creation in the project phase comes to nearly NOK 3 billion and that the project will contribute about 2,300 person-years of employment in Northern Norway throughout the development period. This exceeds the expectations in the impact assessment. The Norwegian share of the project is nearly 65 percent and the project generates 52 500 person years nationwide in total.

The Johan Castberg field development provides important infrastructure in a new oil province in the Barents Sea, and new volumes have been discovered in the area. In 2022 Equinor and partners made two new discoveries to be considered tied in to Johan Castberg and we plan for further exploration in the areas around Johan Castberg in the years to come.

  • The Equinor-operated discoveries Skrugard from 2011, Havis from 2012 and Drivis from 2014 constitute what is now the Johan Castberg project.
  • The proven volumes in Johan Castberg are estimated at between 400 and 650 million barrels of oil.
  • Johan Castberg is designed for a daily production of 30,000 Sm3 oil equivalents (near 190,000 barrels)
  • Location: Johan Castberg is located approx. 100 kilometres north of the Snøhvit field in the Barents Sea in blocks 7219/9 and 7220/4,5,7, around 240 km from Melkøya and 150 km from Goliat. The water depth is 360-390 metres, and Skrugard and Havis are 7 km apart.
  • Discoveries: Skrugard April 2011, Havis January 2012, Drivis May 2014.
