The External Pulling Tool is designed to undertake various HWO and coiled tubing operations. A nozzle is attached to the nose of the tool to create internal pressure so as to move the unbalanced piston. There are a number of nozzle sizes available in the market which gives an ease to the operators to choose the best operating parameters that suit the standard external profiles.
