ABSTRACT:
A method for improving drilling performance of a drilling tool assembly is disclosed. The method includes identifying a drilling performance parameter to be improved. One or more potential solutions are defined to improve the drilling performance parameter. A drilling simulation is performed to determine the dynamic response of the drilling tool assembly during a drilling operation. Determining the dynamic response includes determining the interaction of a cutting element of a drill bit with an earth formation. Improvement in the drilling performance parameter is determined based upon the drilling simulation.
