3 Type Tekst Dato oppdatert Utbygging Reservoar Utvinning Transport Status ODs Faktasider Ekofisk er et oljefelt i den sørlige delen av norsk sektor i Nordsjøen. Havdybden i området er meter. et startet opp i 1971, og produserte til tankskip inntil en lagringstank i betong ble installert i Siden den gang har feltet blitt utviklet med en rekke innretninger, inkludert annlegg for tilknyttede felt og eksportrørledninger. Flere av disse er fjernet eller venter på disponering. Den første feltutbyggingen begynte med tre produksjonsplattformer: Ekofisk A, Ekofisk B og Ekofisk C. Brønnhodeplattform Ekofisk X og prosessplattform Ekofisk J ble installert i henholdsvis 1996 og 1998, som en del av Ekofisk II-prosjektet. I 2005 ble brønnhodeplattform Ekofisk M installert, som en del av Ekofisk Vekst-prosjektet. En plan for vanninjeksjon på Ekofisk ble godkjent i Ekofisk K, som er hovedinnretning for vanninjeksjon, startet injeksjon fra 1987 og er fremdeles i drift. Det har også vært vanninjeksjon fra Ekofisk W fra 1989 til Den ble nedstengt i 2009, og injeksjonen ble erstattet av en bunnramme, Ekofisk VA. Plan for utbygging (PUD) for Ekofisk Sør ble godkjent i Prosjektet omfatter to nye innretninger: produksjonsplattform Ekofisk Z og en bunnramme for vanninjeksjon, Ekofisk VB. Injeksjon fra Ekofisk VB og produksjon fra Ekofisk Z begynte i Boliginnretningene Ekofisk H og Ekofisk Q ble erstattet av Ekofisk L i Ekofiskfeltet produserer fra naturlig oppsprukket kritt av tidlig paleocen alder i Ekofiskformasjonen og av senkritt alder i Torformasjonen. Reservoarbergartene har høy porøsitet, men lav permabilitet. Reservoaret har en oljekolonne på over 300 meter og ligger meter under havoverflaten. Ekofisk ble opprinnelig produsert med naturlig trykkavlastning og hadde en forventet utvinningsgrad på 17 prosent. Senere har vanninjeksjon bidratt til en betydelig økning i oljeutvinningen. Omfattende vanninjeksjon begynte i 1987, og i de etterfølgende årene har området for vanninjeksjon blitt utvidet i flere faser. Erfaringer har vist at vannet fortrenger oljen langt mer effektivt enn ventet, og den endelige utvinningsgraden på Ekofisk er estimert til over 50 prosent. I tillegg til vanninjeksjon gir sammenpressingen av det myke krittet ekstra trykk i dreneringen av feltet. Reservoarkompaksjonen har ført til at havbunnen har sunket med mer enn til meter, spesielt i den sentrale delen av feltet. Det er ventet at innsynkingen vil fortsette, men ikke så kraftig. Olje og gass sendes til eksportrørledninger via prosessanlegget på Ekofisk J. Gass fra Ekofisk-området transporteres via Norpipe til Emden i Tyskland, mens oljen sendes i Norpipe til Teesside i Storbritannia. Produksjonen fra Ekofisk opprettholdes på et høyt nivå gjennom vanninjeksjon og kontinuerlig boring av nye produksjons- og injeksjonsbrønner. Seismikksystemet, Life of Field Seismic (LoFS), som ble installert i 2010, gir data for overvåkning av vannstrømning og reservoarstyring, samt observasjon av dynamiske forandringer i overliggende lag. Boring av flere brønner pågår som en del av utbyggingsprosjektet «Ekofisk Sør». En ny injeksjonsramme vurderes installert for å forbedre vannflømmingen Investeringer (forventede) Side 3 av 18
