Patent ID: 8316940

Claim:
A method of treating a subterranean formation for reducing a flow of aqueous liquids through the subterranean formation comprising the steps of: a. injecting a water control agent composition into the subterranean formation through a wellbore, the water control agent composition comprising a soluble sodium silicate, an activator, and a hydrolysable organosilane compound that hydrolyzes to produce a silanol reactive intermediate; b. allowing the soluble sodium silicate and the activator to set and form a plurality of silicate particles to seal the subterranean formation to prevent water production; and c. allowing the silanol reactive intermediate to (1) condense to form a polysiloxane; (2) react with the siliceous grains of the formation to covalently bind the subterranean formation to the silicate particles; and (3) bind the silicate particles from setting of the soluble sodium silicate to each other.
