         Figure 12.5 Polymer flooding projects in the world.





























         Figure 12.6 Results of polymer flooding projects implementation.

           Fig. 12.6 shows successful completed projects and the additional oil produced.
         As can be seen the use of polymer flooding can significantly increase the oil recov-
         ery coefficient.
           The vast majority of polymers for flooding are based on acrylamide-based poly-
         mers (Pusher, PAA-HPAM) due to their good water solubility, good surface activity
