A process for drilling subterranean wells and the finishing of multiple from a common bore wells and one set for the guidance of a cable of drill pipe and tube revestimentFor the finishing of such multiple wells.The assembly comprising a mouth pit located on or near the earth's surface and positioned above the hole common to wells.At least two tubes positioned inside the hole common to wells, and means positioned in the mouth of the well to segregate and support tubes.According to the process, at least one underground well is drilled through one of the tubes and the inside of an underground formation.It may be produced hydrocarbons from an underground formation to the surface through the pipes of coating production and / or tubes positioned within the borehole to borehole subterru00e2neO. other holes for underground wells may be drilled in a similar way through other tubes of the assembly.
