Development

Hugin is a field in the Yggdrasil area in the central North Sea, 20 kilometres east of the Frigg field. The water depth is 120 metres. Hugin consists of three discoveries: Frigg Gamma Delta, Rind and Langfjellet. The first discovery was made in 1986 when Frigg Gamma was discovered. The plan for development and operation (PDO) was approved in June 2023. The plan comprises the development of the Hugin discoveries and the redevelopment of the Frøy field. The development concept includes a process facility with living quarters, Hugin A, and a normally unmanned facility at Frøy, Hugin B, as well as subsea templates tied-back to Hugin A. Hugin A will be the field centre for the Yggdrasil area.

Reservoir

The reservoirs contain oil and gas in sandstone mainly of Eocene age in the Frigg Formation and of Middle Jurassic age in the Hugin Formation, at depths of 1900 and 3500 metres, respectively. The Hugin area is geologically complex, and the deposits have varying reservoir and fluid properties.

Recovery strategy

Langfjellet, Frøy and Rind will be produced with pressure support by water injection. Frigg Gamma Delta will be produced by pressure depletion, and the produced water is planned to be reinjected into the water zone.

Transport

The gas will be exported through a pipeline from Hugin A to Statpipe and the Kårstø terminal. The oil will be exported through pipeline from Hugin A to the Grane oil pipeline and further to the Sture terminal.

Status

The field is under development. The development of Hugin is coordinated with the development of the Fulla and Munin fields in the Yggdrasil area. The production is planned to start in 2027. Nearby prospects may be tested in a later drilling campaign and produced through remaining well slots.
