ABSTRACT:
Methods of preparing viscous aqueous polymer solutions having improved viscosity and stability properties for use in the treatment of subterranean hydrocarbon-containing formations and in enhanced oil recovery processes are provided. More particularly, a method of preparing such viscous aqueous polymer solution in a buffer system that contains a particular buffer and a substantially oxygen free aqueous solvent. Such solvent is used for pH control and contains one or more metal salts.
