Abstract
En fremgangsmåte for å forbedre utvinningen av olje fra et reservoar beskrives. Fremgangsmåten har trinnet a) innføring av et overfyllingsfluid i reservoaret og b) ekstrahering av oljen gjennom et brønnhull ved en lokalitet forskjellig fra innføringspunktet for overfyllingsfluid i reservoaret. Overfyllingsfluidet inneholder vann og en mengde av en eller flere ikke-polymere viskoelastiske surfaktanter tilstrekkelig til å gi en grenseflatespenning på omtrent 1 mNm eller mindre og en viskositet på omtrent 10 cPs eller mer. Nevnte ene eller flere surfaktanter er selektert fra gruppen bestående av én eller flere kationiske surfaktanter, én eller flere zwitterioniske surfaktanter, én eller flere amfotære surfaktanter, én eller flere anioniske surfaktanter, og kombinasjoner derav.
