25/2-5 Lille Frøy is a discovery in the central North Sea, 20 kilometres southeast of the Frigg field. The water depth is 120 metres. The discovery was proven in 1976. The reservoir contains oil and gas in sandstone of Middle Jurassic age in the Hugin Formation and Late Triassic age in the Statfjord Group, at depths of 3,300 and 3,600 metres, respectively. The plan is to develop Lille Frøy as part of the Yggdrasil development (formerly NOAKA), together with other discoveries and abandoned fields in the area between the Oseberg and Alvheim fields. In December 2022, three plans for development and operation (PDO) were submitted for the Yggdrasil development, including the projects Hugin, Fulla and Munin. The PDO for Hugin includes the development of Lille Frøy as a subsea tie-back to a new process platform, Hugin A, located at Frigg-GammaDelta in the southern part of the Yggdrasil area.
