AROMATIC COMPOUND WITH AQUEOUS HYDROPHILIC POLYMER FLUID D#76,672-F ABSTRACT OF THE DISCLOSURE Disclosed is an improved viscous, aqueous, hydrophilic polymer-containing fluid suitable for injection into porous media such as subterranean petroleum-containing earth formations and an oil recovery method in which the aqueous fluid is injected into the subterranean petroleum- containing formation. The fluid contains an effective amount of an aromatic treating substance, preferrably benzene, toluene, xylene, and low alkyl-substituted benzene or toluene. The improvement resulting from incorporation of this additive in the polymer fluid includes greatly increased resistance to microbial degradation of the polymer, improved screen factor, and improves the injectivity of the fluid.
