USING MODELS AND RELATIONSHIPS TO OBTAIN MORE EFFICIENT DRILLING USING AUTOMATIC DRILLING APPARATUS

A method for controlling an automatic drilling system includes measuring at least one drilling operating parameter applied to a drill string disposed in a wellbore when the drill string is suspended above the bottom of a wellbore. The drill string is lowered to drill the wellbore when the wellbore....

description A method for controlling an automatic drilling system includes measuring at least one drilling operating parameter applied to a drill string disposed in a wellbore when the drill string is suspended above the bottom of a wellbore. The drill string is lowered to drill the wellbore when the wellbore. At least one relationship is established between the at least one measured drilling operating parameter and corresponding values of a drilling response parameter at the surface and at the bottom of the drill string. A value of a rate of penetration parameter at surface is selected to operate the automatic drilling system so as to optimize a rate of penetration parameter at the bottom of the drill string.
