Abstract
Methods and systems are provided for automated closed-loop control of drilling trajectory during directional drilling, which automatically adjusts at least one parameter during the 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. In embodiments, the closed-loop control can be configured to automatically adjust a steering ratio (SR) parameter that controls time that a steering tool will spend in holding a desired magnetic toolface.
