DECT - Downhole Electric Cutting Tool


DECT

Precision pipe cutting, eliminating use of explosives or chemicals

The Downhole Electric Cutting Tool (DECT) is an electrically powered, mechanical pipe cutting tool with multiple sensor measurements to monitor and control the depth of penetration. The resulting cut has a machine shop finish which ensures efficient pipe retrieval. Approximate cutting time in 5”,19.5lb/ft. drill pipe is four minutes.

APPLICATIONS

  • Cuts drill pipe, heavy weight drill pipe and tubing during drilling and completion operations
  • Cuts tubing, packer mandrels and annular safety valves during well intervention and P&A operations
  • Cuts tubing in high scale environment

 

KEY FEATURES

  • E-Line conveyed, powered device
  • Cuts pipe in both tension or compression
  • Cuts pipe in all orientations from vertical to horizontal
  • Run on standard mono-conductor cable and combinable with PowerTrac® in highly deviated/horizontal wells
  • Cuts all grades of low and high alloy steels
  • Unaffected and able to cut through thick/hard scale
  • Cuts pipe up to 1” thickness
  • Operates in gas, oil, brine or drilling mud
  • Multiple cuts possible during single run
  • Machine shop quality finish on cut
  • Monitoring of penetration using multiple measurements
  • Two sizes DECT001/DEC 002 range of 3”- 6”/ 41/2”-7 5/8

 

BENEFITS

  • QHSE; no personnel exposure to explosives and/or chemicals
  • Reduced logistics, time and cost as no dangerous goods certificates, radio silence or special permits for work required
  • High assurance of success in pipe recovery operations due to capability to handle wide range of steels and well conditions
  • Improved operational efficiency due to speed and quality of cut
