摘要：
Methods and compositions are provided that include a water-in-oil composition comprising an oil-based continuous phase and a discontinuous phase that comprises at least a plurality of hydrogel droplets and a method comprising providing a water-in-oil emulsion comprising an oil-based continuous phase and a discontinuous phase that comprises at least a plurality of hydrogel droplets; and placing the water-in-oil emulsion in a well bore penetrating a subterranean formation. Additional methods are also provided.
