With Expandable Bit
The Well Miller Expandable Bit is primarily used for scale milling and provides operators with a better way to intervene and gain access to wells with restrictions resulting from scale build up and debris.
It can pass through small ID and expand to a larger OD when activated.

Well Miller expandable bit for scale milling provides operators with a better way to overcome well restrictions.
It can pass through small ID and expand to a larger OD when activated. The bit will retract if communication is lost to the tool. Using only e-line tools, scale, debris, and even nipple profiles or other restrictions can be eliminated to allow 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.
