ABSTRACT:
High molecular weight N,N-dimethylacrylamide copolymers and terpolymers were synthesized. These polymers offer outstanding advantages as injection water viscosifiers in enhanced oil recovery processes including chemical, miscible, and steam or in processes requiring profile improvement through adsorption and/or gelation. They are very valuable in applications where high salinity is a problem since they are relatively insensitive to metal salts (such as those containing polyvalent ions, such as Ca.sup.++ and Mg.sup.++).
