A process for the extraction of crude oil from an underground deposit which is penetrated by at least one injection well and at least one production well is disclosed. The process comprises forcing a solution or a dispersion of a surfactant co-solvent mixture into the injection well, wherein the surfactant is an alkyl (poly)glycoside of formula (I) R－O－Zn wherein R is a linear or branched, saturated or unsaturated C7-24 alkyl radical, and Zn is an (oligo)glycosyl radical having, on average, n=1 to 10 hexose or pentose units or a mixture thereof.
