ABSTRACT:
The invention provides for a composition for treating a subterranean formation, the composition comprising a water-swellable agent and a sealing agent. Preferably, the water-swellable agent: i) absorbs greater than 100 weight % of water; and ii) swells to greater than 100 weight % as it absorbs water. Preferably the sealing agent: i) is greater than 0.01 weight % soluble in water; and ii) forms a three dimensional gel structure in water. The invention also provides for a method of treating a subterranean formation penetrated by a wellbore, the method comprising the steps of: a) introducing a sealing agent into the subterranean formation; and b) introducing a water-swellable agent into the subterranean formation.
