An expandible packer provides a crescent-shaped cross-sectional area for more and larger diameter data cable and fluid control conduits by eccentrically offsetting the packer mandrel relative to the expandable element. The expandible element of the packer eccentrically surrounds the mandrel to provide an eccentric volume zone between the packer collars. One or more data cable or fluid carrier conduits may be laid between the collars within this eccentric zone, all of greater diameter than would be possible within an annulus between two concentric mandrels. The eccentric zone conduits are secured and protected by a compliant filler material such as rubber or other elastomer that is applied around and between the control conduits within the eccentric zone. This filler material is trimmed or cast to a substantially cylindrical surface about an axis that is substantially coextensive with the expandable element axis.
