. Gullfaks C produces 250000 oilbbl/d of oil. Gullfaks C was completed in 1980. The Tordis field, which is located 11 km south east of Gullfaks C, has a subsea separation manifold installed in 2007 which is tied-back to the existing Gullfaks infrastructure.

Between November 2009 and May 2010, a well being drilled from Gullfaks C experienced multiple well control incidents which were investigated by the Norwegian Petroleum Safety Authority and summarized in a report released on 19 November 2010. The report stated that only chance prevented the final and most serious incident on May 19, 2010 from becoming a full-scale disaster.
