FixedBlade^® Stabilizers

Technical Summary

The FixedBlade stabilizer is ideal for all drilling locations in vertical or deviated wells where drilling gauges are clearly established. With its enhanced hydrodynamic design, created using industry standard computational fluid dynamic modelling, the FixedBlade stabilizer serves to reduce balling whilst increasing overall drilling efficiency.

The unique profile and blade orientation improve BHA stabilization by reducing torque, drag, and 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.

Design Features Benefits

• Dome-shaped, low friction blades
• 6 or 8 points of contact
• Flow profile with optimized hydrodynamics

Benefits

• Reduced torque and drag
• Improved weight transfer and tool face control when slide drilling
• BHA vibration dampening
• Increased stability
• Resistance to balling up and packing off
• Reduced risk of swab and surge
• Minimized damage to mud cake while drilling and tripping

Features

Blade geometry and configuration:

The six blade orientation and smooth dome profile provide three key benefits

1. Improved weight transfer when slide drilling minimizes hanging up, motor stalls and subsequent loss of tool face as well as the onset of excessive stick/slip in rotary mode.
2. The balanced front and back wellbore contact points improve stabilization through improved wellbore coverage and by reducing friction and dampening drillstring harmonics.
3. The hydrodynamic design enhances hole cleaning performance through enhanced displacement of cuttings and fluid.

Hydrodynamic Design:

The FixedBlade stabilizer offers a simple yet innovative solution that enhances drilling performance, prevents downhole failures, and makes tripping easier.

FixedBlade^® Bitbox Stabilizers

The FixedBlade® Bitbox stabilizer directional drilling tool was designed to address the known shortcomings of drill bit stabilization. Utilizing the FixedBlade hydrodynamic design, enables enhanced fluid displacement and near bit stabilization without compromising steerability or torque levels.

The FixedBlade® Bitbox stabilizer was designed to replace the need for static motor sleeve stabilization, improving weight transfer and tool face control when slide drilling. This design bitbox is also suitable for BHA's with point-the-bit RSS, allowing the use of short-gauge bits without compromising directional performance and hole quality. It could also help maintain angle in vertical or tangent sections when used with point- or push-the-bit RSS.

Bitbox Stabilizer Applications

The FixedBlade® Bitbox stabilizer is placed directly above the bit and has three points of contact with the wellbore. It is equally suited for use on either mud motor or RSS applications. The Bitbox stabilizer improves bit stability, minimizing whirl and spiraling.

On steerable motors the rotating bit box stab replaces the static bearing-housing motor sleeve, reducing friction and improving weight transfer when slide drilling. That minimizes the risk of hanging up, motor stalling, and subsequent loss of tool face.

When running with point-the-bit RSS, it allows using regular drill bits with short gauge without compromising hole quality. Similar to other FixedBlade® stabilizers, it has low-friction dome-shaped blades. The Bitbox stabilizer also has superior hydrodynamic properties providing resistance to balling up and packing off.

Benefits

• Improved weight transfer and tool face control when slide drilling
• Improved bit stability
• Reduced torque and drag
• BHA vibration dampening
• Resistance to balling up and packing off
• Reduced risk of swab and surge
• Minimized damage to mud cake while drilling and tripping
