Abstract

Anvendelse av en blanding omfattende en surfaktant og en kosurfaktant i form av en vandig oppløsning for overfylling av undergrunns forekomster av hydrokarboner for mobilisering og utvinning av hydrokarboner fra de undergrunns forekomster, idet kosurfaktanten er en substans eller en gruppe av substanser selektert fra den følgende liste: - en amfifil kampolymer med en hovedkjede med to eller flere sidekjeder festet til hovedkjeden, idet sidekjedene er forskjellige fra hverandre og/eller sidekjedene er forskjellig fra hovedkjeden i sin amfifile karakter, - en amfifil polymer med en eller flere hydrofobe subenheter [A2] basert på en polyisobutenblokk, idet minst 50 mol% av dennes polyisobuten makromolekyler har terminalt arrangerte dobbeltbindinger, og en eller flere hydrofile subenheter [B2], eller - en amfifil polymer med den generelle strukturformel
