Abstract:
A method and apparatus for controlling drilling, the method comprising ascertaining a current position and attitude of a drilling structure, obtaining a desired end point for the drilling structure, creating an optimized geometric Hermite curve path for the drilling structure from the current position and attitude of the drilling structure to the desired end point for the drilling structure and controlling a drilling of the drilling structure from the current position and attitude of the drilling structure to the desired end point for the drilling structure along the optimized geometric Hermite curve path.
