Abstract
A method can include determining that measured outputs of first and second sensors are correlated, calculating a second sensor output based on the measured first sensor output, and in response to a loss of the measured second sensor output or a failure of an item of equipment, controlling a drilling operation based on the calculated second sensor output. A control system can include a statistical model that determines a correlation between measured outputs of first and second sensors, and calculates a calculated second sensor output based on the measured first sensor output, a controller that controls the drilling operation, and a hydraulics model that determines how the drilling operation should be controlled to achieve a desired objective, and determines, based on the calculated second sensor output, how the drilling operation should be controlled, in response to a loss of the measured second sensor output or an equipment failure.
