Description
If you have ever been faced with trying to pull your drill string out of a hole due to overpulls, tight spots, swelling shales, unstable formations, gumbo, or well bore instability the REACTv Sub is the solution. The REACTv Sub is an in-situ hydraulically actuated stabilized reamer with forced balanced cutters and torque reduction features.
The REACTv Sub is powered by a 1.5 – 2.2 stage inverted motor power section with seal assemblies that ensure no fluid discharge into the annulus.
The REACTv Sub design ensures simple seamless torque transfer from the tool across the borehole walls for efficient reaming action. It replaces the use of agitators, shock subs, stabilizers, and concentric reamers in a single tool
Features
- Smooth leading edge for smoother transfer of energy
- Energy-balanced cutter placement
- Depth of cut control
- Hydraulically powered inverted motor power section
- Nozzled rotor for better transmission of telemetry data
- Can be bored to meet specific diameters if re-entry is desired
Advantages
- Improved hole cleaning
- Less hole rugosity
- Better hole quality
- Reduction in back reaming, wiper trips and check trips requirements
- Better weight transfer to bit and BHA
- Reduction in drilling torque
- Reduced side forces when steering/ drilling directionally
- Reduction/ elimination of destructive drill string vibrations
- Reduction/ elimination of stuck pipe incidents
