Rhino Hydraulic Underreamer
Rhino integrated borehole enlargement system
Underream while drilling in a single run.
Wired multicycle hydraulic underreamer
Rhino integrated borehole enlargement system
Overview
Complete control, reliable communication
The Rhino™ wired multicycle hydraulic underreamer is part of the rugged, precision-engineered Rhino integrated borehole enlargement system—a family of hydraulically actuated reamers that save rig time and bring production online faster by underreaming and drilling in a single run.
Building on the capabilities of the Rhino multicycle hydraulic underreamer, Rhino wired multicycle hydraulic underreamer delivers on-demand hydraulic activation with full wired communication for rathole elimination applications. It provides complete control of reamer activation, eliminating pumpdown device activation.
Additionally, the reamer’s flow actuation changes the reaming mode in minutes, reducing reamer activation time and enabling an unlimited number of activation cycles during a run.
Applications
- Hole enlargement while drilling
- Mud systems with high solids content
- Lost circulation material (LCM) as background treatments
- Deep water
- Extended-reach wells
- Highly abrasive environments
- Swelling formations
