Abstract
An apparatus for, and method of identifying a potential problem with a bottom hole assembly (“BHA”) combination that is used in a drilling operation. The method includes monitoring, using a sensor, an actual drilling parameter; comparing the actual drilling parameter to a target drilling parameter to determine a deviation; creating, in response to the deviation and by a feedback control loop system that references an electronic database, instructions thereby omitting variability associated with human input in creating the instructions; monitoring, using the controller, a change in the deviation; determining that the change in the deviation is below a threshold; and determining, based on the change in the deviation being below the threshold, that there is a potential problem with the BHA combination. The BHA combination comprises a mud motor and a drill bit.
