Abstract (en)
Disclosed herein is a method for optimising drilling performance of a roller cone drill bit, comprising simulating drilling with the bit in a selected earth formation to determine at least one drilling performance parameter, adjusting, an orientation of at least one non-axisymmetric cutting element on the bit, repeating the simulating the drilling and determining the at least one performance parameter, and repeating the adjusting and simulating the drilling until the at least one performance parameter is determined to be at an optimum value.
