摘要： Embodiments relate to improving the performance of anionic friction reducing polymers in water containing multivalent ions. Exemplary embodiments relate to methods of improving the performance of anionic friction reducing polymers in a subterranean treatment, wherein the method comprises adding a complexing agent to water comprising multivalent ions. The method comprises adding the anionic friction reducing polymer to the water comprising the multivalent ions, wherein the anionic friction reducing polymer is added in an amount less than or equal to about 0.15% by weight of the water. The method comprises introducing the water comprising the multivalent ions, the complexing agent and the anionic friction reducing polymer into at least a portion of the subterranean formation such that the friction reducing polymer reduces energy loss due to turbulence in the water. The complexing agent complexes with at least a portion of the multivalent ions in the water such that the reduction of energy loss by the friction reducing polymer is improved.
