Abstract
A method for drilling a well includes applying energy input to a drill string () by at least one of rotating the drill string () from surface and operating a drilling motor () disposed in the drill string () to operate a drill bit () at a bottom of the drill string (); an amount of the applied energy not consumed in drilling formations caused by at least one of motion, deformation, and interaction of the drill string () is calculated; an amount of the applied energy used to drill formations below the drill bit () is calculated; and at least one drilling operating parameter is adjusted based on energy calculation before or during drilling operation.
