QUICK FACTS
Technology developed in co-operation with Equinor, Innovation Norway and Research Council of Norway. Patented technology.
The Swarfix® WCT operates using a unique, active swarf capture system designed to imporve the exisitng conventional way of swarf collection by string magnets. As milling debris is generated, the WCT’s integrated components work together to ensure complete, controlled downhole collection:
This closed-loop process prevents swarf from re-entering the wellbore, reduces HSE risks, and ensures predictable operational performance.
Description:
The patented Swarfix® Well Cleaning Tool (WCT) actively collects, stores and secures swarf in a sealed container downhole during milling operations — leaving return flow above Swarfix®WCT, swarf-free.
The 1338 model is designed for casing exits in the 13 3/8″–14″ range, with proven performance in whipstock window milling operations.
The 958 model is designed for casing exits in the 9 5/8″–10 3/4″ range, delivering the same active swarf capture performance as the 1338 model in smaller casing sizes.
