Abstract
A make-up control method and system for creating a threaded connection between a first tubular and a second tubular are provided. The make-up control system including a top drive connected to the first tubular and a controller operably connected to the top drive that sends at least one command signal to the top drive. The top drive generating a torque and a rotational speed in response to the at least one command signal that are applied to the first tubular during a make-up process between the first and second tubulars. The top drive also generating a torque feedback signal that is transmitted to the controller. The controller using the feedback signals to monitor the torque and rotational speed that are applied to the first tubular during the make-up process. The controller halting the make-up process when a predetermined torque limit is reached.
