Patent attributes
A system includes a tool mandrel securable to a landing nipple and a prong receptacle coupled to a lower end of the tool mandrel. The prong receptacle includes a central bore and a pressure release port in communication with the central bore. The system also includes an equalizing prong initially securable within the tool mandrel in a run-in position. Further, the system includes a tubular prong extension coupled to the equalizing prong. An upper end of the tubular prong extension extends up out of the tool mandrel. Moreover, axially downward movement of the tubular prong extension from the run-in position to a set position secures the tool mandrel to the landing nipple, and axially upward movement of the tubular prong extension from the set position to a released position disengages the tool mandrel from the landing nipple.
