ABSTRACT:
An improved apparatus for transmitting signals through a well tool is provided. In a broad aspect, the present invention is a communication conduit in a well tool comprising: a cylindrical mandrel having a longitudinal bore therethrough, an inner diameter, an outer diameter, and an outside circumference; a well tool attached to the outside circumference of the cylindrical mandrel; and at least one signal transmitting passageway positioned in the mandrel between the inner diameter and the outer diameter. In a specific embodiment, the well tool may be a packer. The at least one signal transmitting passageway may be used as a carrier for electrical or fiber optic conductors, or it may be a pressure retaining member whereby pressurized hydraulic fluid may be passed through to a device below the well tool without interruption.
