Based on the same patent and proven cutting technology of the EZ-cutter, XS & XL Cutters will enable clean and perfectly controlled cuts without using explosives, chemicals or other expensive Work-Over alternatives. Simplifying transportation, logistics and safety issues, XS and XL cutters will be easily deployable on any logging unit. The only significant requirement will be a conductive fluid in the well, like brine or sea water. After anchoring the instrument inside the casing, a quick operation to remove rust and scale deposits is initiated before supplying the electrodes with power. A controlled groove starts and deepens with time until the first perforated zone is identified. A penetration regulator then avoids the electrodes to be stuck before the end of the cut.

XS Cutter : Initial Prototype : June 2021

XS Cutter has the objective to cut small size pipes, of nominal diameter between 2-7/8’’ and 7-5/8’’. The XS Cutter project is to integrate both Oil & Gas conditions and Well intervention technologies. It will connect on any Production logging cables.

  • O.D. : 2″
  • Casing to cut : 2-7/8″ to 7-5/8″
  • Works in highly deviated wells
  • Navigates through dog legs
  • Able to enter a 2-1/2’’ WPCE
  • Max. Working Pressure : 10 000 PSI
  • Max. Working Temperature : 100°C (soon 150°C)
  • Real time control of the groove evolution

XL Cutter : Initial Prototype : September 2021

XL Cutter has the objective to cut large size diameter casings, of nominal diameter between 7’’ et 20’’. This innovative casing cutter shall integrate 12 arms mounted electrodes in order to significantly reduce the cutting times (3 hours instead of the EZ cutter 9 hours for a 45,5 lbs/ft 10-3/4’’ casing, as an example). Logging cable might be of reduced length or of larger diameter and the number of electrodes is increased in order to deal with improved cutting times.

  • O.D. : 5″
  • Casing to cut : 7″ to 20″
  • Deployable anchoring system
  • Able to enter 6’’ WPCE
  • Pressure, Temperature and Deviation conditions are not considered tough as large size casings only concern shallow depths (6000 ft max) and vertical wells.
  • Real time control of the groove evolution
