Abstract:
A weight down tool comprises a central mandrel configured to be coupled to a wellbore tubular, a plurality of outwardly extending hunter lugs disposed about the central mandrel, and a plurality of radially expandable weight down lugs disposed about the central mandrel. The hunter lugs are configured to retract in response to moving through an upper restriction in a downwards direction and to expand the weight down lugs into an expanded position in response to moving through the upper restriction in an upwards direction. The weight down lugs are configured to retract out of the expanded position in response to moving through the upper restriction in an upwards direction.
