High Ratio underreamer

ROCK TO ROCK P&A solution

The ProMILL Underreamer is designed to enlarged wellbore sections up to 100% of the pilot diameter. The tool has a long reach of arms relative to the tool body diameter. This allows it to easily drift through the narrow casing restriction and then open the hole to the minimum half inch diameter over the original hole size.

Applications & Features:

• Plug & Abandonment operations to provide rock-to-rock isolation
• Remove excess cement, filter cake and open hole to expose virgin formation
• PDC cutter arms capable of underreaming variable formations
• Reduces rig time by eliminating additional trips to underream after completing a section milled window
