Sleeve Stabilizers and Extended Reach Drilling (ERD)

Challenges in ERD
·Severe Torque and Drag
Long horizontal sections create high friction that can compromise drilling performance and hole quality.
·Trajectory Maintenance
Accurate steering over thousands of meters requires perfect centralization and minimized borehole deviation.

Sleeve Stabilizer Solutions
1.Optimized Blade Profiles
Designed for low-resistance passage while maintaining high stabilization in long horizontal runs.

2.Custom Sleeves for Specific Sections
Operators use harder sleeves in abrasive formations and softer sleeves in clay-rich zones to optimize ROP and reduce vibration.

3.Mandrel Reusability Across Laterals
In pad drilling scenarios, the same mandrel can be reused across multiple wells with different sleeve configurations.

Success Snapshot
In a North Sea ERD well (over 12,000 ft lateral), the operator reported:
·No stick-slip incidents
·8% faster ROP than forecasted
·Lower friction factor by 0.03 compared to previous BHA

Sleeve stabilizers are enabling longer, more efficient ERD wells by providing customized, consistent stabilization across extended lateral sections.
