Well Miller®

for hardware milling

Introduction

The Well Miller® for Hardware Milling optimizes the repair of wells with mechanical problems by milling out the faulty hardware with keyhole precision. Hardware milling is performed in combination with our Well Tractor® to apply weight-on-bit as necessary and counter the reactive torque.

The Well Miller for Nipple Profile Removal (NPR) is developed to increase the ID of a nipple profile, the Well Miller NPR provides increased production and access to the wellbore below for tools with larger diameters. We have also successfully applied the Well Miller NPR to open up pipe or tubulars which have partially collapsed. Our track record speaks of successfully removing nipples of high tensile steel, chrome, and super chrome.

The Well Miller for Plug Removal (PR)
A powerful solution for removing faulty or temporary plugs in the wellbore. Even the hardest materials such as cast iron or composite plugs can easily be milled out with the Well Miller PR.

The Well Miller Valve Opening (VO) If valves malfunction the Well Miller VO can help restore production to the well by milling out a predetermined part of the valve. When a control line fails or a valve doesn’t open, it affects both production and wellbore access below the valve. A swift solution is therefore always desired. The Well Miller VO is able to quickly and safely restore the flow path.

The Well Miller Valve Removal (VR)
Flapper valves, half and full-ball valves and isolation valves pose no obstacle for the Well Miller VR. Valves made of high tensile steel, chrome, super chrome, incoloy and inconel are easily removed to establish or even increase production.

The Well Miller Ball Seat Removal (BSR)
The tool has been designed especially for milling out balls and ball seats to increase flow and allow access to lower completions. Through the years we have successfully milled out balls and ball seats made of cast iron and composite materials.

Overview

The Well Miller® provides operators with a better way to repair wells with mechanical problems. 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.
