Method of viscosifying aqueous fluids and process for recovery of hydrocarbons from subterranean formations

Patent ·
OSTI ID:5429017

The present invention relates to a method of viscosifying aqueous fluids and a viscosifying composition which when admixed with an aqueous fluid produces a viscosity increase in the fluid in excess of the additive viscosity of the individual composition components. The viscosifying composition comprises xanthan gum and at least one memeber selected from the group consisting of the ammonium, hydrogen or alkali metal salts of polystyrene sulfonate, polyvinyl sulfonate and hydrolyzed copolymers of styrene sulfonate and maleic anhydride.
