SwarfPak – The universal solution

Main challenges in traditional milling :

•Swarf to surface creates logistical and environmental challenges

•Swarf size is large often creating bird nesting and pack-offs

•Milling speed is low – normally less than 3 m/hr

•High vibrations

•Knives / Cutters wear fast and often multiple runs are needed to mill a 50 m section

SwarfPak - Technical Goals :

•Swarf left down-hole

•Swarf size optimized and at a controlled and homogenous size

•Milling speed: 18 – 30 m/hr!!

•Reduces vibrations

•Milling of 50 m section in 1 run

Swarf Challenges:

• Bird nesting, Pack-Offs, etc

• Hole Cleaning,

• Formation fracturing

SwarfPak Goals:

• Cutting Swarf Continously

while machining

• Optimizing & Secure Swarf Size

• Optimizing Performance

SwarfPak – Testing Status

Early size

Various testing has been performed to optimize swarf size.

We have now developed a very homogenous and small swarf.
