A method of drilling a well includes at least one drill bit and at least one secondary cutting structure. The method includes determining a neutral point of a drill string, positioning at least one secondary cutting structure based on the neutral point of the drill string, and drilling an earth formation.

Method for optimizing the location of a secondary cutting structure component in a drill string

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.
