ECCENTRIC REAMING, MULTI-POINT STABILIZATION, AND AN AGITATING FUNCTION
ALL-IN-ONE TOOL

ClearPath Eccentric Reamer
ClearPath Eccentric Reamer
Multifunctional Drilling Technology
An innovative multifunctional tool combining reaming, drilling, wellbore conditioning, improved stabilization, and hole cleaning capabilities.
Applications: Reaming while drilling in vertical, deviated, and extended reach wells.
Introduction
As technology has advanced in the directional drilling industry, it has facilitated the drilling of deeper, and more complex well trajectories, faster than ever before. Wellbore quality issues, whether related to either hole geometry, hole cleaning or formations could lead to the wellbore drift diameter being smaller, increased friction, tight spots, higher upper rotary torque, reduced actual weight on bit and even unnecessary and premature BHA component wear.
FEatures
The ClearPath Eccentric Reamer is aimed towards addressing and alleviating aforementioned issues by integrating the following design features:
- Single piece integral assembly
- Eccentric blade design → opposing eccentric reamer blades
- Progressive low-torque helical hybrid cutting structure → 2-stage wellbore conditioning
- Premium selection of PDC Cutters → cutter and insert optimization
- Multi-point stabilization
- Hydrodynamically positioned inner blades
- Drilling cuttings agitator
- Low torque hybrid cutting structure → incrementally shear the formation
- Bi-directional cutting configuration
BENEFITS
• Increases drift size • Eliminates the need for dedicated wiper trips; • Removes horizontal section misalignment, ledges, key seats, and micro doglegs • Eases tripping and subsequent casing running • Reams out spiral patterns • Reduces stick and slip • Increases energy transfer to the bit and reduced drill string drag • Improves weight transfer to the bit • Helps extend bit and motor life • Shortens trip times • Minimizes downhole vibration • Reduces risk of stuck pipe • Reduces risk of packing off • Reduces torque and drag in drilling mode • Improves control of ECD (Equivalent Circulating Density) • Creates cleaner and more stable wellbore conditions

differentiatiors
- Hybrid multi-functional model combining reaming, stabilization, and agitation features in a single tool
- Enhanced transportation of cuttings and fluid across the tool due to unique hydrodynamic design resulting in better hole cleaning
- Hydrodynamically positioned mid-tool features designed to stir low side cutting beds in horizontal well sections
- Provides 2-stage wellbore conditioning through its unique multi-blade insert design
