Description

Introduction
Drilling highly reactive, unconsolidated, inter-bedded and similarly troublesome zones, especially with tortuous extended reach well paths, all-too-often induces non-productive time (NPT) to deal with stuck pipe and other wellbore instability issues. Project costs are further aggravated when post-drilling reaming runs are required to minimize tortuosity and condition the wellbore for the completion and production hardware.

Benefits
• Minimal NPT while drilling and tripping
• Faster drilling rates with lower torque and drag than conventional tools
• Enhanced wellbore stability
• Reduced costs
• Elimination of dedicated reaming trips
• Unimpaired MWD/LWD logs
• Increased durability for longer runs
• Effective reaming without the need for conventional and often obstructive stabilizers
• A smooth and ready-for-completion wellbore
