Abstract
A method of making a controlled swell-rate swellable packer comprises disposing a sealing element about at least a portion of the mandrel, applying a mask onto at least a portion an outer surface of the sealing element, wherein the sealing element comprises a swellable material, and wherein the mask comprises void spaces, and applying a jacket to the sealing element not covered by the mask. The jacket may be disposed such that it 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. The mask may be removed from the sealing element after applying the jacket to the sealing element not covered by the mask.
