ABSTRACT:
Two or more opposing and outward facing profiles are fabricated and joined to each other along their outer edges, forming a section of a guide string. The sections of the guide string are secured together in an assembly and lowered into a single conductor. The assembly lands on the bottom of the well and may support its own weight. The guide string defines two separate longitudinal cavities or sections of the well. Each separate cavity allows drilling and installation of casing in the conductor.
