Fixedblade® stabilizer
Designed to address the known issues of the conventional blade stabilizer.
Enhanced Hydrodynamic Design
The Fixedblade Stabilizer offers a simple yet innovative solution that enhances drilling performance, prevents downhole failures and makes tripping easier.
Optimized Flow Profile
Dome-Shaped Low Friction Blades
Hydrodynamic Flutes
Reduce torque, drag & torsional vibration
The Stabilizer Reinvented
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
The six blade orientation and smooth dome profile have three key benefits
- Improved weight transfer when slide drilling minimises hanging up, motor stalls and subsequent loss of tool face as well as the onset of excessive stick/slip in rotary mode.
- The balanced front and back wellbore contact points improves stabilisation by reducing friction and dampening drillstring harmonics.
- The hydrodynamic design enhances hole cleaning performance whilst optimizing vibration mitigation at source.
The enhanced hole cleaning ability aids ECD management by limiting pack off tendency which reduces borehole erosion when tripping and backreaming. Better drill fluid displacement reduces the risk of swab and surge in comparison to conventional blade stabilisers – a key cause of wellbore instability.
