What happened PLD-COIL TUBING PARTS WHILE
PULLING OUT OF WELLBORE A coil tubing (CT)
operation had completed drilling out plugs,
circulating the well bore and started pulling out
of the hole. After pulling out approximately 9
ft., the tubing parted at the surface just
outside of the gooseneck. The parted end of the
2 tubing on the spool side of the break recoiled
towards the spool and struck the operators cab
visor and windshield, cracking the safety glass.
The well was immediately secured per established
procedures. A buffer zone was in effect and the
immediate area was clear of personnel.
Investigation is currently underway.

• Preliminary Learning Points
• Hazard Identification - During JSA and pre-job
  safety meetings, hazards and mitigation steps
  were identified and communicated to all involved
  site personnel.
• Buffer Zone was in effect - clear of personnel
  Before travelling in or out of well bore, buffer
  zones around the Coil Tubing unit and wellhead
  were established and enforced.
• Coil Tubing Integrity - All elements pertaining
  to the condition of the pipe must be considered
  before the job is started (CT reel log time in
  service, gas service, fluid pumped, well bore
  fluids exposure, etc.)
• Tubing on Reel must be secured Procedures and
  necessary equipment/tools should be available to
  secure the reel end of the tubing should a
  similar failure occur to prevent additional
  spinning or flaring out of reeled tubing.
