This oil field lies in block 34/7 in the Tampen area of the Norwegian North Sea, and came on stream in 1994.
In addition to the main Tordis structure, the development embraces the Tordis East (1998), Borg (1999) and Tordis South East (2001) fields.
These discoveries have all been developed with subsea installations. Water depth is roughly 200 metres.
Water injection is used to maintain pressure in the reservoirs.
Oil from Tordis is piped to the Gullfaks C platform 10 kilometres away for processing, storage and export.
