METHOD FOR STANDARDIZED EVALUATION OF DRILLING UNIT PERFORMANCE

摘要

A method for evaluating drilling unit performance includes automatically identifying at least one operating state of a drilling unit during operations thereof that is independent of conditions in a wellbore. Start times and stop times of the at least one operating state are determined. The automatically identifying and determining start and stop times are performed by comparing at least one drilling unit operating parameter measurement to a set of stored measurements corresponding to the operating state. An elapsed time of the at least one operating state is determined from the start times and the stop times. The elapsed time for the drilling unit is compared to a predetermined reference standard.
