Abstract: A method is provided for improved degradation of metal-crosslinked polymer gels, which are useful in oil and gas treating operations. In this method a polysaccharide having a higher degree of substitution than the polymer in the polymer gel is added to the gel. The polysaccharide removes the crosslinking metal ion from the gel to thus break down the gel and reduce its viscosity.
