Abstract
Methods and computer systems for performing and using drilling simulations. The drilling simulations can be used to improve drilling performance or demonstrate drilling performance of a drilling profile. One method for creating a drilling profile includes obtaining drilling profile data and performing a drilling simulation using at least a portion of the drilling profile data. Modifications are then recommended for the drilling profile data.
