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
