Abstract
A method for optimizing borehole drilling by a drill string having a drill bit at a rotated and axially urged to drill formations includes measuring a parameter related to at least axial and torsional motion of a drill string propagating as elastic waves at a selected position along the drill string. An axial force exerted by the drill bit and torque applied to the drill bit are determined from the measurements related to at least axial and torsional motion. A confined compressive strength of the formations is determined from the measurements related to at least axial and torsional motion. At least one of the determined axial force and the determined torque is adjusted such that a mechanical specific energy applied to the formation is closest in value to the confined compressive strength.
