PrecisionBrush

Precision cleaning of tubing and profiles

The PrecisionBrush is used to clean tubing and completion components by removing thin deposits of rust and scale that could affect sealing integrity or mechanical functionality. It is run in combination with PowerTrac® for anchoring and conveyance, coupled with a Direct Drive Rotation (DDR) device to generate the required rotational force.

APPLICATIONS

  • Removal of debris affecting seal integrity
  • Cleaning plug setting areas
  • Brushing of downhole safety valve flow tube cavities and nipple profiles
  • Removal of rust, scale, wax etc. from tubing seal bores and profiles
  • Preventive maintenance in scale environment

Key Features

  • E-Line conveyed, powered device
  • Customisable brush bottom hole assembly (BHA)
  • Expandable brush BHA elements expand PrecisionBrush on activation and retract on deactivation

BENEFITS

  • Cost effective preventive maintenance and repair option compared to coiled tubing, hydraulic workover units or workover rigs
  • Precise, low-risk wellbore cleanout service
  • Expandable brush passes through restrictions and expands to the profile to be cleaned
  • Light on logistics, footprint, personnel and time
