FixedBlade Stabilizer
THE STABILIZER REINVENTED
Reduce Torque, Drag & Torsional Vibration
The Fixedblade Stabilizer is ideal for all drilling locations in vertical or deviated wells where drilling gauges are clearly established. With its enhanced hydrodynamic shape, created using industry standard computational fluid dynamic modelling, the Fixedblade Stabilizer serves to reduce clay balling whilst increasing overall drilling efficiency.
The unique profile and blade orientation improves BHA stabilization by reducing torque, drag and torsional vibration – all key causes of borehole enlargement and subsequent BHA component failure.
The Fixedblade Stabilizer is a direct replacement to conventional drilling stabilizers and can be used in any drilling application.
FIXEDBLADE STABILIZER FEATURES
Design Features
- Dome-shaped, low friction blades
- 6 points of contact with the 5-3/4″ and 14-1/2″ hole sizes
- 8 points of contact with the 16-1/2″ and 26″ hole sizes
- Flow profile with optimized hydrodynamics
Benefits
- Reduced torque and drag
- Improved weight transfer and tool face control when slide drilling
- BHA vibration dampening, low pad pressure
- Increased stability for BHA components and concentric hole openers
- Resistance to balling-up and packing-off
- Reduced risk of swab and surge and reducing ECD while drilling
- Minimized damage to mud cake while drilling and tripping
