Abstract
An improved gravel pack material includes granules of a swellable elastomer selected to trigger by a surrounding fluid. When a fluid breakthrough occurs in a gravel-packed well, the swellable elastomer granules swell in the presence of the fluid at the point of the breakthrough, sealing off or reducing the flow of the fluid through the breakthrough into the well.
