ABSTRACT:
A packer for a subterranean well conduit providing an electrical conduit bypass comprises a top sub having a first eccentric bore connectable between a tubing string and a mandrel and a second eccentric passage sealingly receiving an electrical conduit. A tubular body assembly is shearably connected to the top sub and mounts an annular packing element, an annular cylinder and piston unit and an annular slip and cone assemblage in axially stacked, abutting relationship. A support block secured to the lower end of the mandrel supports the electrical conduit and secures the lower cone against relative movement so that extension of said cylinder and piston effects setting of the packer. Upward movement of the top sub effects unsetting and retrieval of the packer.
