  • Patent number: 4232739
    Abstract: The injectability, filterability and stability, especially resistance to precipitation on contact with water containing relatively high content of boron salts such as borates, of an aqueous polysaccharide-containing fluid for use in viscous oil recovery operations is improved by prehydrating the polysaccharide in fresh water of low boron content followed by shearing for a period of time sufficient to provide desirable filtration properties following by dilution with field brine followed by a second shearing step prior to injecting the aqueous fluid into the formation.
