The Well Miller® Expandable Bit for hardware milling provides operators with a better way to repair wells with mechanical obstacles. It can pass through small ID and expand to a larger OD when activated.
The bit will extract if communication is lost to the tool. Using only e-line tools, nipple profiles or other restrictions can be eliminated or increased, plugs can be removed, failed isolation valves can be milled through for production or access to deeper parts of the wellbore. The Well Miller® is run in combination with the Well Tractor® for precise control of weight on bit and to counter reactive torque.
