- providing a rig structure having a top drive operatively connected thereto;
providing a gripping member, operatively connected to the top drive, for gripping the first threaded downhole tubular;
gripping the first threaded downhole tubular with the gripping member;
aligning a first thread on the first threaded downhole tubular with respect to a second thread on the second threaded downhole tubular;
operating the top drive, thereby rotating the gripping member and the first threaded downhole tubular and thereby inter-engaging the first and second threads;
measuring a torque developed at the inter-engaging first and second threads during make-up;
controlling the top drive to adjust the torque in response to the measured torque and prior to an indication of shouldering between the first and second threaded downhole tubulars; and
continue making the threaded connection after adjustment of the torque.
