ABSTRACT:
An aqueous liquid medium having increased low shear viscosity and utility as a mobility control agent in enhanced oil recovery is provided by dispersing into the aqueous medium (1) a hydrophilic/hydrophobic polymer having hydrophobic groups, e.g., an acrylamide/dodecyl methacrylate copolymer, and (2) a water-dispersible surfactant, e.g., dodecyl polyethyleneoxy glycol monoether.
