Abstract
A water-soluble inorganic non-crosslinking salt is incorporated in an aqueous gel-like solution of a water-soluble uncrosslinked polymer at an initial higher polymer concentration. The salt accelerates the dilution of the polymer solution with an aqueous diluent to an aqueous polymer solution at a predetermined lower polymer concentration. The gel-like polymer solution is diluted without substantially degrading the polymer so that it retains desirable properties for use in a hydrocarbon recovery process.
