ABSTRACT:
An improved method and apparatus for automatically controlling the direction of advance of a rotary drill to produce a borehole profile substantially as preplanned with minimal curvature while maintaining optimum drilling performance. The system is capable of storing a planned path for the borehole. Information relating to the profile of the actual drill path is compared to the planned path and an appropriate correction signal is generated and used to cause the borehole to be drilled in accordance with the planned path.
