16/1-12 (Edvard Grieg Sør)

16/1-12 (Rolvsnes) is a discovery in the central part of the North Sea, just south of the Edvard Grieg field. The water depth is 100 metres. The discovery was proven in 2009, and subsequently delineated by well 16/1-25 S in 2015. The reservoir contains oil in weathered and fractured granitic basement beneath a thin layer of Lower Cretaceous conglomerate. The Rolvsnes discovery will probably be developed as a subsea tie-back to the Edvard Grieg field. An appraisal well was drilled in 2018 and gave encouraging results. Depending on the outcome of post-well studies and further work, a plan for development and operation (PDO) may be submitted in 2021.
