Field synthesis system and method for optimizing a drilling device using offset log data

A system and method for optimizing the performance of a drilling device utilizes well logs and drilling parameters from multiple offset wells located in proximity to the location of a desired wellbore. The well logs and drilling parameters data from the offset wells is synthesized (316) to determine major drilling contexts including both geological trends, mechanical properties and the different well profiles. The performance of one or more drilling devices and or drilling parameters is then simulated (324) within the selected drilling contexts of the offset wells. The simulation information is then used to select an optimized drilling device or parameter for drilling the selected wellbore.
