Gullfaks- has been still is an important field to develop, prove and qualify new subsea technologies Early production Gullfaks A 1986 using new subsea tech (6 wells) Gullfaks Satellites (40 wells) came in production from 1998 (to GFA) and 2001 (to GFC) using new qualified technologies (HOST, 7- HXT,Smart wells, heated flowlines, new flowline alloys, reeled pipe in pipe, bundles) The Gullfaks Sør Brent reservoir, producing from the L and M templates (7 wells) to GFC, is the main source of gas from Tampen fields towards Kårstø. Subsea Compression : The pressure has declined since 2001. In 2015, the wells will need Subsea Compression to keep production rates at todays level.
