Abstract

A method may include receiving a digital well plan that specifies planned drilling parameters for drilling a borehole, where each of the specified planned drilling parameters includes one or more of a minimum threshold and a maximum threshold; generating statistical distributions of actual drilling parameters in real-time responsive to receipt of real-time data acquired during a depth-based window for the drilling; generating comparisons in real-time, where each of the comparisons is between one of the statistical distributions and a corresponding one of the planned drilling parameters for the depth-based window; and, responsive to one or more of the comparisons indicating an unacceptable actual to planned parameter deviation, issuing a control signal.
