ABSTRACT:
A new method is provided for improved degradation of metal-crosslinked polymer gels which are useful in oil and gas well treating operations. In this method an esterified carboxylated chelator is added to the gel. At elevated temperatures, the esterified chelator undergoes hydrolysis to form an acid and an active ligand which subsequently removes the crosslinking metal ion from the gel and hydrolyses the polymer.
