摘要
Method and apparatus for providing access to a lower end wellbore through an impasse using an circumferential adaptable apparatus and downhole devices to pilot a tool string through an existing obstructive frictional or restricted passageway with dissimilar well bore walls, wherein piloting a tool string may comprise displacing debris within and/or deforming its proximally circular and/or deformed bores or traversing an obstructive passageway therebetween, and whereby various downhole devices may be incorporated, deployed and oriented relative to a proximal axis or proximally contiguous wall, using the expandable and collapsible members of the present invention engaged about a plurality of shafts, usable to pilot the tool string through a conventional impasse or restriction of said walls of said dissimilar contiguous passageways.
