Abstract
Present embodiments are directed to a drilling system and method for evaluating energy consumption to determine the onset of drilling issues and identify mitigation strategies for more efficient drilling. The drilling system receives drilling parameter values and a drilling performance value from sensors located on a drilling rig, and calculates an energy value based on the drilling parameter values and drilling performance value. The drilling system determines a deviation of the calculated energy value from a desired energy value and identifies one drilling parameter that significantly correlates with the deviation. Further, the drilling system determines an adjustment to the one drilling parameter that, when applied, causes the calculated energy value to approach the desired energy value. The drilling system then indicates the desired adjustment to the drilling operator so that appropriate actions may be taken to mitigate the drilling issue.
