ABSTRACT:
A device for guiding the lower end of a pipe string, or the like, past an upwardly facing shoulder in a well in which rotation of the pipe string is prohibited. When the guiding device lodges on such shoulder, the pipe string is lifted and lowered a few times, this reciprocating action actuating an indexing mechanism in the guide tool and causing the lower end of the guide tool to rotate so that a slanted guide surface thereon is brought around to the point of lodging to dislodge the guide tool from the shoulder and guide the pipe string therepast.
