Today, a typical section milling performed before a plugging operation involves downwards milling with extreme vibrations and consequently knife wear and damage. In addition there is a lot of trouble involved in bringing the milling swarf to surface, separate it out into skips, sending it onshore and then transport it to a safe place for deposition. The whole process is extremely in-effective and costly.

The new SwarfPak challenges this principle with its upwards milling practice leaving the milling swarf downhole. Introducing Gravel Pack (reverse flow) principles allows the milling swarf to be left downhole.
