Equinor has started production at the Halten East development in the Norwegian Sea, two years following approval from Norwegian authorities.
Halten East is a tie-in development located in the Kristin-Åsgard area in the Norwegian Sea. Vår Energi and Petoro are partners. The development consists of six gas discoveries and flexibility for three prospects in addition, utilizing existing infrastructure and processing capacity at Åsgard B.
The plan for development and operation (PDO) was approved by authorities in February of 2023.
Now, gas from the first well Gamma is on stream two years later, on plan. The first phase consists of six wells from five discoveries. The second phase is planned in 2029. It will include a sidetrack and an additional three possible wells. The total investment of the project is around $843 million (NOK 9 billion) for both phases.
The reservoirs of Halten East contain gas and condensate. The recoverable reserves are estimated to be around 100 million barrels of oil equivalent from the discoveries. The gas will be sent to Kårstø from Åsgard B, from where it will be exported to Europe via pipeline.
In November 2024, Equinor acquired Sval Energi’s 11.8% share in the Halten East Unit, increasing its operating ownership to 69.5%. Other partners in the development are Vår Energi with 24.6%s stake, Petoro with 5.9%.
“We are starting up Halten East at a time where piped gas from Norway is in high demand and important for energy security. In a challenging cost and inflation environment, the project has been delivered both on time and within our cost estimate,” said Geir Tungesvik, executive vice president for projects, drilling, and procurement in Equinor.
