Abstract
Methods and systems are provided for automated closed-loop control of drilling trajectory during directional drilling, which define target inclinations and/or target azimuths for a sequence of automated control loops performed over distances of measured depth during directional drilling, wherein the sequence of automated control loops transition from drilling a curve or bend in a wellbore to drilling a horizontal or lateral section or tangent section of the wellbore. In embodiments, the sequence of automated control loops can be configured to incrementally change dog leg severity of the wellbore in a pre-defined manner with the final dog leg severity being at or near zero.
