A packer for a subterranean oil and/or gas well. The packer has a control signal bypass passage incorporated in the packer body. The control signal bypass passage may be opened and closed via reeled tubing to selectively allow and disallow passage of a control signal through the packer. The packer supports an electric submersible pump for enhancing flow of well fluids. The control signal bypass passage of the packer connects with a control line from the surface and with a separate control line extending downhole from the packer in the well. The control line, downhole from the packer, connects with a safety valve operable by control signal passed from the surface, through the packer, and downhole through the control signal bypass passage of the packer.
