  1/9-1 Tommeliten Alpha is a discovery near the border to the UK sector in the southern part of the Norwegian sector in the North Sea, 25 kilometres southwest of the Ekofisk field. Tommeliten Alpha was proven in 1977 and is considered as a cross-border petroleum deposit. The water depth is 75 metres. The reservoir contains gas condensate and volatile oil in chalk in the Paleocene Ekofisk Formation and Upper Cretaceous Tor Formation. It lies at a depth of about 3,000 metres. The discovery is planned to be developed as subsea tie-back to the Ekofisk Centre and plan for development and operation (PDO) was submitted in November 2021.
