Potential Applications
- Oil, gas, and offshore wells
- Vertical, horizontal and extended reach drilling wells with high degree wellbore deviation (up to 400 per 30 m)
- Wells with aggressive H2S and CO2 environments
Factors of Improved Reliability
- Special thread hooked profile with a negative angle protecs the connection from dissemble when running the strings
- Gas-tight metal-to-metal seal assembly ensures that the connection can withstand high bending and compression loads
- Additional inner internal shoulder provides resistance to high torques
- An increased connection ID allows for more flexibility in selecting downhole equipment
- Inspection of thread connection assembly based on specified make-up torques and an assembly diagram
- OMK POLAR design has been verified by successful bench testing per ISO 13679 CAL IV
- CLEAN SPACE dope-free technology option
- High-torque modification of OMK POLAR HT for casing pipes operation under extreme conditions, during running and cementing with rotation, as well as for drilling while casing
