Abstract: Process for tertiary mineral oil production in which an aqueous injection fluid comprising at least a water soluble polyacrylamide-(co)polymer dissolved in the aqueous fluid is injected into a mineral oil deposit and the aqueous injection fluid is prepared by mixing a liquid dispersion polymer composition comprising particles of polyacrylamide-(co)polymers dispersed in an organic, hydrophobic liquid with an aqueous fluid. Preferably, the process is carried out on an off-shore production site.
