Abstract
A method for plugging a permeable zone or leak in a subterranean formation comprises introducing into the formation a cross-linkable organic polymer and a cross-linking composition which comprises a zirconium triethanolamine complex, a tetra(hydroxyalkyl)ethylenediamine, water and optionally, a polyol. The method can be used for cross-linking organic polymers over a wide range of pH. By varying the composition and optionally adding a delay agent, the method provides flexibility in rate of cross-linking.
