Abstract
A method of sealing a space in a wellbore formed in an earth formation comprises inserting a plurality of swellable particles into the space by pumping them in a carrier fluid, the particles being susceptible to swelling upon contact with a selected fluid, and inducing the selected fluid to contact the swelleable particles whereby the swelleable particles swell so as to form a body of swollen particles in the space.
