Claim Text:
1. A method of drilling a wellbore through subterranean formation, the method comprising: (a) receiving data regarding at least two drilling operational parameters related to wellbore drilling operations into an operating parameter database; (b) computing a mathematical objective function based upon the received data for input into each of a global search engine and a local search engine; (c) inputting the computed objective function and received data into the global search engine to create a global response surface, and to identify at least two global-engine recommended drilling parameters; (d) inputting the computed objective function and received data into the local search engine to determine a significantly correlated drilling parameter, and to identify at least two local-engine recommended drilling parameters based upon the significantly correlated controllable drilling parameter; (e) creating a combined dataset using a data fusion process by combining (i) the created global response surface, and (ii) the determined significantly correlated controllable drilling parameter and the local-engine recommended drilling parameters; (f) using a decision tree process on the data fusion combined dataset to determine whether to define a status mode of the combined dataset as at least one of a learning mode and an application mode; determining operational updates to at least one of the at least two controllable drilling parameters based at least in part on the further optimized recommendation; and implementing at least one of the determined operational updates in the wellbore drilling operations.
