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.
45° Backward Jet
Maintains turbulent flow while keeping debris in suspension and creating a hydraulic swab cup.
Automatic Cycling Mode
Enables seamless operation by automatically cycling between milling and jetting modes with no surface input required.
True “Bit Sub” Access
Crossover compatible with true “bit sub” flexibility and multiple thread options.
Engineered to create a big impact on the most intricate applications, each UJT configuration is designed with optimized tensile, torsional, and flow ratings to maximize hole cleaning and material recovery.
