CONTROLLED SWELL-RATE SWELLABLE PACKER AND METHOD

摘要

A controlled swell-rate swellable packer comprises a mandrel; a sealing element, and a jacket. The sealing element is disposed about at least a portion of the mandrel, and the jacket covers at least a portion of an outer surface of the sealing element. The jacket is configured to substantially prevent fluid communication between a fluid disposed outside of the jacket and the portion of the outer surface of the sealing element covered by the jacket.
