Abstract
A tieback tool (10) and method for connecting tieback conductors (12) to a well system (14) where misalignment occurs between the tool and the well system including a body (40) having an externally threaded dog ring (44) which engages the throats of J-slots (34) in the well system and which initially serves to align the tieback tool to the well system. Rotation of the tieback tool after initial alignment actuates the threaded dog ring (44) in the tieback tool to lock and seal the tieback tool into the well system.
