Development

Munin is located in in the Yggdrasil area in the central North Sea, 35 kilometres south of the Oseberg field. The water depth is 110 metres. The field comprises several discoveries and extends over 200 square kilometres. The first discovery was made in 1997 with well 30/11-5. Since then, a further ten discoveries have been made. The discovery wellbore for Munin is 30/11-8 S, drilled in 2011. The plan for development and operation (PDO) was approved in June 2023. The development concept includes subsea tie-back of the deposits to an unmanned processing platform located in the northern part of the Yggdrasil area. The PDO includes drilling of several untested structures which can be produced through available well slots or may trigger more subsea templates in the area. The platform will be tied-back to the Hugin A processing platform in the southern Yggdrasil area.

Reservoir

The reservoirs contain gas and oil mainly in Middle Jurassic sandstone of the Brent Group at depths of 3,200-3,650 metres. The Munin area is geologically complex, and the deposits have varying reservoir and fluid properties.

Recovery strategy

The deposits will be produced with different recovery strategies. The largest oil deposits will be produced with water injection, while gas deposits and smaller oil deposits will be produced by pressure depletion. Gas lift will also be utilised for oil deposits.

Transport

The gas will be exported in a new pipeline from Hugin A via Statpipe to the Kårstø terminal. The oil will be transported to the Hugin A facility for further processing and transport.

Status

The field is under development. The development of Munin is coordinated with the development of the Hugin and Fulla fields in the Yggdrasil area. The production is planned to start in 2027.
