The Deviation Control Challenge
Unstable BHAs cause:
-Excessive doglegs (>8°/100ft) leading to stuck pipe
-Accelerated drill string wear costing $500K/well in replacements
-Poor hole cleaning increasing equivalent circulating density (ECD) risks
Our spiral stabilizers deliver:
✅ 65% lower vibration than straight-blade designs
✅ 3x service life with advanced hardfacing options
✅ ±0.15° inclination control in directional wells
Engineered for Performance
Spiral vs. Straight Blade Design
Feature Spiral Stabilizer Straight-Blade Stabilizer
Rotation Smooth torque transmission High rotational vibration
Hole Cleaning Aggressive cuttings transport Poor fluid mobilization
Stick-Slip 40-50% reduction Minimal reduction
Applications Directional, horizontal, curved sections Vertical wells only
HF Hardfacing Technology Matrix
Grade Hardness (HRC) Application Life Extension
HF1000 58-62 Soft formations (shale, clay) 2x conventional
