DevelopmentHalten Øst is a field in the Norwegian Sea, just east of the Åsgard field. It consists of six discoveries: Natalia, Sigrid, Nona, Flyndretind, Gamma and Harepus, spread out within 65 kilometres between Natalia in the north to Mikkel Sør in the south. The water depth is 200-300 metres. The discoveries will be developed together, and the plan for development and operation (PDO) was approved in February 2023. The development concept includes five subsea templates tied-back to the existing infrastructure on the Åsgard field.
ReservoirThe reservoirs contain mainly gas and condensate in Lower to Upper Jurassic sandstone in the Tilje, Tofte, Ile, Garn and Melke Formations. They are located at depths between 2000 and 3000 metres. Common for all these reservoirs is that the volumes are relatively small, but the reservoir properties are excellent.
Recovery strategyThe drainage strategy is pressure depletion with aquifer support.
TransportThe oil and condensate will be transported from Åsgard to the market by tankers. The gas will be exported via the Åsgard Transport System (ÅTS) to the terminal at Kårstø.
StatusHalten Øst will be developed in two phases. Production from the first and second phase is scheduled to start in 2025 and 2029, respectively.
