1. A method for automated closed-loop control of drilling trajectory during directional drilling, the method comprising:
automatically adjusting at least one parameter during directional drilling to automatically control the direction of drilling when drilling a kickoff that transitions a wellbore from a vertical section to a curve or tangent section, wherein the at least one parameter comprises a steering ratio (SR) parameter that controls time that a steering tool will spend in holding a desired magnetic toolface, wherein the automatic adjustment of the steering ratio (SR) parameter is based on a ramp of multiple magnetic toolfaces or magnetic toolface set-point nudges using estimated or elapsed measured depth during drilling.
