High-speed precision milling
The Axter Lateral Miller is a programmable, high-speed precision milling tool designed for accurate and controlled downhole operations — so precise that you could write your name with it.
In plug and abandonment (P&A) and intervention scenarios, the miller creates a precise 200 mm (7.9”) window in production tubing, enabling controlled access to control lines without the need for full tubing removal. Its advanced multi-axis control ensures clean, targeted milling while preserving the integrity of surrounding components.
Capabilities and applications
This rigless, electro-mechanical milling solution streamlines P&A, intervention, and retrieval operations, delivering a cost-effective, high-precision approach to downhole milling.
| Applications |
| Plug and abandonment |
| Tubing cutting |
| Milling windows in tubing to allow for removal of control lines and fiber optic cables from the annulus |
| Creating slots/windows in wellbore tubulars |
| Milling holes in tubing to allow circulation |
| Milling restrictions to increase ID of nipples and other completion equipment |
| Milling weak points and profiles in the wellbore |
| Penetrate (cross boring) the hydraulic bore in TRSCSSV to allow for installation of a WRSCSSV |
| Cutting shunt tubes |
| Machining e.g. Nipple profiles |
