Abstract:
A system and method of directionally steering a bottom hole assembly (“BHA”) from a drilling rig to a target location including by receiving data indicative of a directional trend of the BHA and a projection to bit depth; determining a location of the BHA based on a directional trend and the projection; identifying an amount of deviation from a drilling path; automatically creating a modified drilling path that intersects the planned drilling path based on the amount of deviation exceeding a first threshold amount of deviation and being less than a second threshold amount of deviation, automatically creating a modified drilling path that does not intersect the planned drilling path in response to the amount of deviation exceeding the second threshold amount of deviation, and determining a curve profile of the modified drilling path having the smallest rate of curvature to avoid drilling overshoot; and steering the BHA.
