Equinor’s Johan Castberg Hits 220,000 bpd Plateau Just Three Months After First Oil

The first cargo from Johan Castberg was loaded by the tanker Bodil Knutsen on 25 May, shipping around 700,000 barrels to Spain

(IN BRIEF) Equinor’s Johan Castberg field reached its intended plateau production of 220,000 barrels per day on 17 June, just three months after its FPSO vessel began operations on 31 March. Seventeen wells are currently online and delivering as forecast. The first cargo of ~700,000 barrels departed on 25 May to Spain. Initial reserves of 450–650 million barrels may be expanded by 250–550 million barrels through further drilling. Plans include six additional wells to maintain peak rates, the Isflak fast-track project (investment decision by year-end, start-up 2028), and annual exploration wells near Johan Castberg and Goliat. The field’s operators—Equinor (46.3 percent), Vår Energi (30 percent), and Petoro (23.7 percent)—anticipate at least 30 years of steady production, bolstering European energy supplies and Northern Norway’s economy.

(PRESS RELEASE) STAVANGER, 20-Jun-2025 — /EuropaWire/ — Equinor ASA (OSE:EQNR, NYSE:EQNR), an oil, gas, wind and solar energy company active in more than 30 markets globally, reports that three months after first oil, the Johan Castberg field is operating at its full design capacity of 220,000 barrels per day, representing a 150 percent increase in Barents Sea output. The floating production, storage, and offloading vessel (FPSO) began production on 31 March, and plateau rates were reached on 17 June after 17 of the field’s 30 wells came online, each performing in line with expectations.

On 25 May, the first shipment of roughly 700,000 barrels was loaded onto the tanker Bodil Knutsen and dispatched to Spain. Current volumes from the Norwegian Continental Shelf are overwhelmingly directed to European markets, supporting regional energy security.

Originally estimated to hold 450–650 million barrels of recoverable oil, the Johan Castberg field now aims to add an additional 250–550 million barrels through planned drilling. Six more production wells are scheduled to sustain plateau output, while the fast-track Isflak development is on track for a final investment decision by year-end and start-up in 2028. Annual exploration drilling—one to two wells per year—will target prospects around Johan Castberg and the nearby Goliat field.

The Johan Castberg partners include Equinor Energi AS (operator, 46.3 percent), Vår Energi ASA (30 percent), and Petoro AS (23.7 percent). According to Equinor’s Executive Vice President for Exploration & Production Norway, Kjetil Hove, the field is expected to produce reliably for at least 30 years, generating substantial value for Norway and employment opportunities in Northern Norway.
