The Johan Castberg field (previously the Skrugard 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 2024, and will produce for 30 years.
In order to achieve profitability in the project after the major oil price drop in 2014-2015, Equinor and its partners needed to change the concept and devise new solutions to realise the development.
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 costs from the original concept have been reduced from approx. NOK 100 billion to approx. NOK 49 billion. 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.
Operation 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. It 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 2 billion and that the project will contribute about 2,000 person-years of employment in Northern Norway throughout the development period. This somewhat exceeds the expectations in the impact assessment. The Norwegian share of the project is nearly 60 percent.
Johan Castberg is a breakthrough in frontier areas where we will need to collaborate with the fishery industry, among others. At the same time, it is a development that will have ripple effects and will be significant for technology and expertise development in the supplier industry—particularly up north.
- 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.
- 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.
