Patented Extended Reach and Wellbore Cleaning Technology.
The Patented Universal Jet Thruster (UJT) Smart Sub is placed below a motor between the bit and the bit box. The natural flow path is altered to jet 45° up hole through nozzles directly above the bit, helping to propel the CT string in-hole. The UJT automatically switches from “Thrust Mode” to “Milling Mode” when WOB is applied, allowing flow through the bit to provide cooling and lift cuttings. Maximize debris recovery and improve ROP with this simple innovation for any milling string.
