Abstract:
An apparatus for, and method of identifying a potential problem with, drilling equipment that is used in a drilling operation. The method includes monitoring an actual drilling parameter associated with the drilling operation; comparing the actual drilling parameter to a target drilling parameter to determine a deviation between the actual and target drilling parameters; creating, using the controller and in response to the deviation, instructions for a control system that controls an aspect of the drilling operation; drilling, using the instructions and the controller, the wellbore; monitoring, using the controller, a change in deviation in response to drilling using the instructions; determining that the change in deviation is below a threshold; and determining, based on the change in deviation being below the threshold, that there is a potential problem with the drilling equipment.
