Abstract
A method of blocking a high permeability channel in communication with a wellbore, including the steps of introducing an amount of an unreinforced gel into the high permeability channel via the wellbore and introducing an amount of a reinforced gel comprising an amount of a reinforcing material into the high permeability channel via the wellbore. The method may further include the step, after introducing the unreinforced gel and the reinforced gel into the high permeability channel, of introducing an amount of a chaser fluid into the wellbore.
