Title: POLYMER FLOODING PRODUCED WATER TREATMENT
Abstract:
The present embodiments generally relate to the treatment of produced water comprising one or more water soluble polymers, wherein such treatment comprises: adding to the produced water at least one iron complex; and degrading at least a portion of the one or more water soluble polymers. This treatment may result in a reduction of the viscosity of said produced water and/or the degradation of the water soluble polymers which are contained therein.
