DCT TurboCaser Data Sheet

TurboCaser™

RAPID DRILL-THRU CASING RUNNING SYSTEM.

The TurboCaser™ is a pass through turbine powered reaming system that enables casings and intermediate liners to be landed at target depth. 

The TurboCaser™ provides high speed rotation of a reamer shoe, independent of casing string rotation.

The casing is cemented in the normal manner. The TurboCaser™ is designed for very rapid drill out. Drill out time of the TurboCaser™ is under 15 minutes and a dedicated drill out trip is not required.

THE BENEFITS

  • Turbine powered reaming
  • Land casing and liners on depth
  • Reduce or eliminate wiper trips
  • Full bore pass thru and drill ahead
  • No string rotation required
  • Low flow rate on start up
  • Stress free casing connections
  • Case trouble zones quickly
  • Reduce well construction risks
  • Maximise ROI
  • Minimise HSE exposure

  • Material grade of the body can be changed on request, lead times may vary.
  • Performance charts are given out separately as they are dependent on the fluid weight being used on casing/completion run.
  • Max drill thru bit size is as stated in tables above, preferably PDC drill bit, but is not required to be.
