  • Automatic drilling advisory system based on correlation model and windowed principal component analysis
    Patent number: 9598947
    Abstract: Methods and systems for controlling drilling operations include using a statistical model to identify at least two controllable drilling parameters having significant correlation to one or more drilling performance measurements. The methods and systems further generate operational recommendations for at least two controllable drilling parameters based at least in part on the statistical model. The operational recommendations are selected to optimize one or more drilling performance measurements.
    Type: Grant
