A well tool and more particularly a hanger or setting tool actuating assembly for hanging a liner in a well or setting various other well equipment in a desired sub-surface position. The actuating assembly includes a magnet which is moved by means controlled remotely therefrom to cause a member magnetically coupled thereto to correspondingly move resulting in setting of the well equipment in the desired location.
A well tool and setting tool assembly comprising: a well tool mandrel, at least a portion of which is of non-magnetic material; a setting tool mandrel coaxially and releasably positioned within said well tool mandrel; magnet means carried on the exterior of said setting tool mandrel and movable adjacent said non-magnetic portion of said well tool mandrel between a first and a second axial position; setting means carried on the exterior of said well tool mandrel; a magnetic-follower member of magnetic material carried on the exterior of said non-magnetic ...
