ABSTRACT:
A pipe conduit bundle for installation into a wellbore using horizontal drilling techniques is disclosed. The pipe conduit does not require an outer casing for construction. The pipe bundle configuration is formed by pipes of varying sizes in a particular configuration, with bindings interspaced along the length of the pipes such that the pipe bundle deflects as a single unit during installation. A pulling head is attached to the bundle, which is hollow to allow liquid entering one pipe to be distributed to other pipes. Liquids such as water may be used to fill the pipes to reduce buoyancy, and thereby reduce drag, during installation of the bundle.
