Welltec, a leading provider of well intervention services, has announced the addition of two groundbreaking solutions to its Well Miller portfolio, significantly enhancing its capabilities in addressing clean-out and downhole access challenges.
The first innovation is a percussive milling solution that has demonstrated remarkable efficiency in scale milling operations.
During extensive testing, this new technology has shown to be three to four times more effective than standard milling options.
The percussive milling solution utilises a rotary hammer action, which allows the bit to maintain constant contact with the target while delivering additional impact energy.
This continuous impact is generated by a toothed cam mechanism, inducing micro-fractures in the scale material and dramatically improving the milling process.
One of the key advantages of this percussive milling solution is its versatility.
The toothed cam mechanism is designed to be expendable and replaceable.
Once fully utilised, operators can continue with standard milling without the need to end the run or pull out of the hole to redress the tool.
Additionally, custom bits are available to provide varying levels of force and frequency, allowing operators to tailor the milling process to specific challenges.
The second addition to the Well Miller portfolio is a dual-rotation milling option, primarily developed for plug removal but also applicable to the removal of flapper valves and other loose hardware.
This innovative technology addresses a common issue in plug milling operations where the target can rotate in reciprocation with the milling action, significantly reducing effectiveness.
The dual-rotation milling solution features a two-part mill bit with inner and outer components that rotate in opposite directions.
This counterrotation effectively nullifies any unwanted rotation of the target during operations, ensuring consistent and efficient milling.
These new additions to Welltec’s Well Miller portfolio demonstrate the company’s commitment to developing advanced solutions for well-intervention challenges.
By improving efficiency and addressing specific operational issues, these innovations are set to provide significant benefits to operators in the oil and gas industry.
As the industry continues to face complex downhole challenges, Welltec’s expanded Well Miller portfolio positions the company at the forefront of well intervention technology, offering operators enhanced tools to optimise performance and efficiency in their operations.
