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