VectorZIEL Rotary Steerable System
The VectorZIEL™ rotary steerable system is an automatic steering
tool for three-dimensional drilling. Offering higher ROP, improved
cuttings removal, and precise trajectory control, the system helps
you produce higher quality boreholes at reduced operational costs.
End Sub
Based on a design that has been developed and refined over
the past 20 years, the VectorZIEL tool offers reliable and precise
directional control, even in the most demanding applications.
The VectorZIEL tool is available for purchase or rental, and it’s
supported by NOV's global maintenance infrastructure, enabling
directional drillers to offer high-tier directional drilling services
around the world.
