    16/1-12 Troldhaugen is a discovery in the central North Sea, just south of the Edvard Grieg field. The water depth is about 100 metres. Troldhaugen was proven in 2009, and subsequently delineated by wells 16/1-25 S in 2015 and 16/1-28 S in 2018. The reservoir contains oil in weathered and fractured granitic basement beneath a thin layer of Lower Cretaceous conglomerate. The authorities have permitted an extended well test (EWT) to better understand the performance of the complex reservoir, and test production was initiated in August 2021. A plan for development and operation (PDO) was submitted to the authorities in December 2022. The development concept is a subsea tie-back including two wells to the Edvard Grieg field via the existing Troldhaugen EWT subsea development. This also provides spare slots for future expansion of the development. Start-up is expected in early 2026.
