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.

Abstract: A method for monitoring an adherence of actual drilling parameters to planned drilling parameters in real-time includes receiving a well plan for a well. The well plan includes a plurality of planned drilling parameters corresponding to a plurality of intervals in the well. The method also includes receiving actual drilling parameters corresponding to the plurality of intervals in the well and comparing the actual drilling parameters to the planned drilling parameters. The method also includes determining a plurality of compliance indicators based at least partially upon the comparison. The compliance indicators indicate a level of adherence between the actual drilling parameters adhere to the planned drilling parameters. The method also includes generating a first alarm in response to greater than a first predetermined amount and less than a second predetermined amount of the compliance indicators being below a planned minimum threshold, above a planned maximum threshold, or both.
