SLIDERTM Technology
While Sliding for Directional Drilling
Top Drive without Slider: Stopped or Sometimes Rocks Pipe Manually
Top Drive with Slider:
Directional Drilling Machine
- Automatic “Rocking” to enhance ROP
- Provides accurate Tool Face Orientation While Drilling
- May Extend the length of the Well (see conditions)
- Avoids Downhole Motor Stalling
- Saves time and consequently $$$
