The present invention provides a method for reducing the amount of water produced from a subterranean formation as a result of stimulation of the subterranean formation. The method comprises the introduction of a first and second reactive polymer which leak-off into the formation and which are capable of subsequently reacting together to form a reaction product which selectively reduces the permeability of the formation to water flow through the formation. The reactive polymers react in situ to form a reaction product that binds to the formation in such a manner that the flow of water is selectively retarded through the matrix while the flow of oil is substantially unaffected.
