ABSTRACT:
A method is provided for swelling water-swellable elements located in a portion of a well. The method comprises the steps of: (A) introducing an oil-in-water emulsion into the portion of the well, wherein the oil-in-water emulsion comprises: (i) an aqueous liquid, wherein the aqueous liquid is the external phase of the oil-in-water emulsion; (ii) a hydrocarbon liquid, wherein the hydrocarbon liquid is an internal phase of the oil-in-water emulsion, and wherein the hydrocarbon liquid is adjacent to the external phase of the oil-in-water emulsion; and (iii) a surfactant; and (B) allowing the oil-in-water emulsion to contact the water-swellable element for a sufficient length of time to cause the thickness of the water-swellable element to expand by a desired percentage, wherein the desired percentage is at least 5%.
