ABSTRACT:
A technique is provided to isolate regions of a wellbore. The technique utilizes a swellable material packer that comprises a layer of swellable material disposed about a tubular member of a completion. When the layer is exposed to a substance that induces swelling of the swellable material, the layer expands between the tubular and a surrounding wall to isolate a region of the wellbore annulus.
