ABSTRACT:
A method is disclosed for selectively reducing the permeability of water producing intervals in a hydrocarbon formation without reducing oil permeability. A soluble oil followed by water is injected into the formation to lower the residual oil saturation. The well is then produced to remove water from any oil zones before injection of an isobutyl-methacrylate solution in acetone. A slug of a non-condensable gas follows the treating solution before the shutting in of the well for up to about one day.
