Abstract
A packer system for a wellbore includes a tubular member and a packer element mounted on the tubular member. The packer element is formed of a swellable polymeric material, the packer element having a radially-outward external surface, the surface including a plurality of radially-inwardly extending recesses formed therein. The recesses provide additional surface area that can contact a swelling fluid, thereby increasing the swelling rate of the packer element.
