Abstract
Systems and methods for subterranean drilling operations comprising: adjusting a wellbore parameter; measuring a time interval between adjustment of the wellbore parameter and a resulting change at a bottom hole assembly of a drill string; using the measured time interval and determining resistance in the wellbore; and modeling the resistance to form a friction model of the wellbore.
