In an improved method for the treatment of a permeable formation or zone adjacent to the bore of an oil well, the setting time of an acid-settable liquid is predictably delayed by use of a novel catalyst system. The method provides an effective means for controlling the reduction of the permeability of the formation or zone in a single stage treatment by dissolving the catalyst in the liquid and introducing the solution into the formation. The catalyst system comprises a mixture of a suitable acid-releasing compound and a base.
