ABSTRACT OF DISCLOSURE A pipe assembly for use in production or drilling systems comprises a plurality of pipe members connected together in end-to-end relationship and a plurality of tubular conductor members electrically connected together in end-to-end relationship. The members have co-operating tapered or stepped portions, and/or screw- threaded portions whereby the pipe members support the conductor members in internal or external coaxial relationship A logging unit can be moved along the assembly unit under fluid pressure to engage stop means for connecting the unit with the conductor members, or a logging unit can be incorporated in a pipe member wall. An outer pipe can surround the pipe assembly to provide with the pipe assembly interior two passages for the reception, flow or circulation of fluids, for example extracted oil and/or gas and barrier fluid.
