High-Speed Reaming Tool (HSRT)
Confident casing deployment in the most challenging wellbores
When tortuosity, instability, or extended open-hole exposure threatens casing deployment, conventional shoes and casing rotation are no longer enough.
The High-Speed Reaming Tool (HSRT) is a fluid-activated, high-speed reaming solution that actively conditions the wellbore without rotating the casing string, enabling smoother deployment, reduced risk, and improved cementing outcomes.
The challenge:
Modern wells push casing deployment to its limits:
- High doglegs and excessive tortuosity
- Unstable or plastic formations
- Extended reach drilling with low TVD-to-MD ratios
- Liners run on systems that cannot be rotated
Traditional casing rotation increases mechanical risk, rig time, and exposure and still does not guarantee reaching depth.
HSRT Solution:
- HSRT uses hydraulic energy to drive a high-speed rotating reaming shoe, actively conditioning the wellbore as casing or liners are run
What this means for your operation:
- Navigates restrictions without rotating the casing
- Maintains forward progression in challenging hole conditions
- Reduce the risk of stuck pipe and non-productive time (NPT)
- Improves wellbore cleanliness before cementing
Features and Benefits
- High-speed rotation: Greater than 1,500 RPM (bearings rated at over 3,000 RPM)
- Fluid activated: no mechanical casing rotation required
- Compact design: approximately 1 m tool length
- Fully-drillable internal drive
- Compatible with drift ID
- Available in all casing sizes and API or premium connections
- Free-rotating nose for smooth wellbore tracking without circulation
- Provides a very important second shear to the cement slurry as it is pumped through the tool
- Reduces NPT during casing deployment increased efficiency when encountering wellbore obstructions
- Increased safety for floor personnel and reduced potential damage to assets
