Abstract
Tools and method for automatically controlling torque when making-up and/or breaking-down threaded connections between downhole assets such as drill pipe, drill collars, and BAH components. An iron roughneck may be controlled by, for instance, automatically monitoring and adjusting the fluid pressure of cylinders that ultimately provide the torque to the downhole assets. The torque may further be automatically controlled by automatically identifying the downhole assets and selecting a corresponding torque profile or target torque. Clamping force may also be controlled, and is optionally proportional to the target torque.
