6 Production started The first shipment from Åsgard A A lot of negative articles was published in the news about this hopeless project. Total Investment inkl. Kårstø and ÅT: 65 BNOK (Budget 48 BNOK) Harald Nordvik CEO in Statoil had to leave his position. Pay back: May 2003 During the first year we had 26 compressor changes! Classification: Internal

7 General Information History 1981 Midgard field discovered (Saga Petroleum) 1984 Smørbukk field discovered (Statoil) 1985 Smørbukk Sør field discovered (Statoil) 1993 Statoil and Saga Petroleum start co-operation for Åsgard field development 1995 Åsgard unit PDO application, unitisation of the Smørbukk, Midgard and Smørbukk Sør fields 1996 PDO approval and project initiation: Åsgard A contracts/construction start, Start predrilling of Smørbukk and Smørbukk Sør wells 1997 Major contracts for Åsgard B (field gas centre), Kårstø expansion, Transport pipelines th of May oil production started from Åsgard A (all gas re-injected) st of October started gas and condensate production from Åsgard B st of October started gas and condensate production from Mikkel by Sub Sea tie in to Åsgard (connection to Midgard Z-template) 2006 Production of Åsgard Blend started The product contains oil and condensate from Åsgard PDO approval Yttergryta (January 18th 2008) th of January started gas and condensate production from Yttergryta.
