Considerable research has been conducted to identify water soluble polymers which can efficiently control the flow properties of displacement fluids for enhanced oil recovery.1–5 Two main types of polymeric viscosifiers have emerged from this research which rely mainly on ultra high molecular weight for thickening efficiency: natural biopolymers such as Xanthan or Scleroglucan and synthetic acrylamide based polymers. Although these polymers possess many useful characteristics, the reservoir conditions in which they can provide adequate mobility control are limited. For example, the biopolymers provide excellent mechanical stability and salt tolerance, however, further improvement in high temperature stability6 would be desirable. Viscosification with acrylamide based polymers depends not only on high molecular weight but also on chain expansion due to ionic charge repulsion or the polyelectrolyte effect. Thus solutions of these polymers are salt sensitive and exhibit poor mechanical7 and thermal stability.8
