Precision Mechanical Applications



Clean and access your well

The PrecisionDebrisMill is used to remove debris preventing access to completion targets, causing internal diameter changes, or choking production/injection. It is run in combination with PowerTrac® for anchoring, coupled with a Direct Drive Rotation (DDR) device to generate the required rotational force. This service is designed without debris collection, with the debris either falling to the bottom of the well for collection in the rathole, or circulated out for surface collection.


  • Removal of a wide range of wellbore debris e.g. scale, asphaltenes, cement stringers, rust
  • Milling out glass plugs


Key Features

  • E-Line conveyed, powered device
  • Combinable with PowerTrac® for conveyance
  • Real-time monitoring of key milling parameters 
  • Can be run with a Hole Opener to achieve precise and smooth milling
  • Optional Shock Absorber and mechanical Straight Pull Release Tool



  • Optimised milling speed, reduced risk of stalling
  • Precise, cost effective and low risk wellbore cleanout service
  • Light on logistics, footprint, personnel and time
