PNG media_image1.png 930 645 media_image1.png Greyscale PNG media_image2.png 681 881 media_image2.png Greyscale Regarding claim 1, the claim recites a method for controlling operations of a drilling rig through a system, the method comprising: acquiring a measured pressure within fluid lines in communication with a wellbore in real time; and calculating a first magnitude of error between the measured pressure and a target pressure; and calculating an output value proportional to the first magnitude of error between the measured pressure and the target pressure, the output value being a pressure rate of change target; and calculating a second magnitude of error between the pressure rate of change target and a pressure rate of change, the pressure rate of change being a difference in the acquired measured pressure and an average of a plurality of prior measured pressures, the difference being divided by an amount of time between the acquired measured pressure and a prior measured pressure; and calculating a second output value that is a sum of a proportional magnitude of real time error between the pressure rate of change target and the pressure rate of change and a proportional sum of a plurality of prior errors between the pressure rate of change target and the pressure rate of change, the second output value being a position setpoint; and using the second output value to generate a process signal; and using the process signal to actuate a pressure control device; and iterating the process to regulate a pressure within a fluid line in communication with a wellbore. Step Analysis 1: Statutory Category? Yes . The claim recites a method; therefore, it is a process 2A - Prong 1: Judicial Exception Recited? Yes . The claim recites the limitation of calculating a first magnitude of error between the measured pressure and a target pressure. This limitation, as drafted, is a process that, under its broadest reasonable interpretation, covers performance of the limitation in the mind; for example, calculating a first magnitude of error between the measured pressure and a target pressure can be done by a human with pen and paper. The claim recites the limitation of calculating an output value proportional to the first magnitude of error between the measured pressure and the target pressure, the output value being a pressure rate of change target. This limitation, as drafted, is a process that, under its broadest reasonable interpretation, covers performance of the limitation in the mind; for example, calculating an output value proportional to the first magnitude of error between the measured pressure and the target pressure can be done by a human with pen and paper. The claim recites the limitation calculating a second magnitude of error between the pressure rate of change target and a pressure rate of change, the pressure rate of change being a difference in the acquired measured pressure and an average of a plurality of prior measured pressures, the difference being divided by an amount of time between the acquired measured pressure and a prior measured pressure. This limitation, as drafted, is a process that, under its broadest reasonable interpretation, covers performance of the limitation in the mind; for example, calculating a second magnitude of error between the pressure rate of change target and a pressure rate of change can performed by a human with pen and paper. The claim recites the limitation of calculating a second output value that is a sum of a proportional magnitude of real time error between the pressure rate of change target and the pressure rate of change and a proportional sum of a plurality of prior errors between the pressure rate of change target and the pressure rate of change, the second output value being a position setpoint.
