Petropedia explains External Pulling Tool

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. The operator can use the fishing neck by pumping with the latch back or by pushing a latch back that allows the tool to directly land on the profile. The benefits of using the tool include:

  • It suits all kind of external profiles.
  • It is field redressable.
