PrecisionCollector

Clean and access your well

The PrecisionCollector is a robust, full system cleanout technology that can remove a wide range of debris types in varying well conditions. It mills, agitates and dislodges the debris downhole, collecting and retaining it in reservoir chambers for transportation out of hole. It is run in combination with PowerTrac® for anchoring and providing weight on bit, coupled with a Direct Drive Rotation (DDR) device to generate the required rotational force.

Applications

  • Removal and collection of a wide range of wellbore debris:
  • Unconsolidated (e.g. proppants, sand)
  • Consolidated (settled barites, hard scale)
  • Vicious (asphaltenes, waxes)
  • Wells where circulation for cleanout is not recommended or not possible

 

KEY FEATURES

  • Robust mechanical collection mechanism, not requiring fluid circulation
  • Mechanical interaction and friction separates debris from fluid, rather than filtration
  • Highest solids recovery content per collected volume of debris
  • Customisable bottom hole assembly (BHA) with operational flexibility depending on debris in well
  • Real-time monitoring of key milling parameters; weight on bit (WOB), bit speed, vibration

 

Benefits

  • Provides loosening, collection and recovery of debris to surface in one run
  • Best technology option if debris composition and consistency is unknown or varying
  • Operates in wet and dry environments
  • Precise, cost effective and low risk wellbore cleanout service
  • Light on logistics, footprint, personnel and time
