A swellable packer comprises an elastomeric element and a mandrel extending through the elastomeric element. The elastomeric element is formed of an elastomer which undergoes swelling following contact with certain types of well fluids. The elastomeric element is sealed with respect to the mandrel and may be located along an undercut region of the mandrel. Additionally, the mandrel has an interior passage extending longitudinally through the mandrel and offset with respect to an external geometry of the mandrel. Accordingly, the mandrel is effectively constructed with relatively thicker and thinner wall sections. The thicker wall section or sections accommodates at least one bypass conduit which extends longitudinally through the mandrel.
