Abstract
Embodiments of the present invention generally relate to methods and apparatus for improving top drive operations. In one embodiment a method of ensuring safe operation of a top drive includes operating a top drive, thereby exerting torque on a first tubular to makeup or breakout a first threaded connection between the first tubular and a second tubular. The method further includes monitoring for break- - out of a second connection between a quill of the top drive and the first tubular; and stopping operation of the top drive and/or notifying an operator of the top drive if break-out of the second connection is detected.

2. The method of claim 1, wherein the second connection is monitored by monitoring the torque and determining if the torque is in a loosening direction of the second connection.
3. The method of claim 2, wherein the second connection is further monitored by detecting a sudden change in the torque if the torque is in a loosening direction of the second connection.
4. The method of claim 3, wherein the second connection is further monitored by measuring rotation of the first tubular if the sudden change in torque is detected.
5. The method of claim 3, wherein:
the second connection is between the quill and a torque head or spear gripping the first tubular, and the second connection is further monitored by measuring rotation of the torque head or spear if the sudden change in torque is detected.
the second connection is between the quill and a torque head or spear gripping the first tubular, and the second connection is further monitored by measuring rotation of the torque head or spear if the sudden change in torque is detected.
6. The method of claim 3, wherein:
the second connection is between the quill and a torque shaft having a strain gage disposed thereon and a turns counter in communication therewith, the torque is monitored using the torque shaft, and the second connection is further monitored by measuring rotation of the torque shaft using the turns counter if the sudden change in torque is detected.
the second connection is between the quill and a torque shaft having a strain gage disposed thereon and a turns counter in communication therewith, the torque is monitored using the torque shaft, and the second connection is further monitored by measuring rotation of the torque shaft using the turns counter if the sudden change in torque is detected.
7. The method of claim 3, wherein the sudden change in torque is detected by calculating a differential of torque with respect to rotation or time and detecting a change in sign of the torque differential.
8. The method of claim 2, wherein the torque is monitored by calculating the torque from power input to the top drive.
9. The method of claim 2, wherein:
the second connection is between the quill and a torque shaft having a strain gage disposed thereon, and the torque is monitored using the torque shaft.

10. The method of claim 2, wherein the torque is monitored using an upper turns counter disposed near an upper longitudinal end of the first tubular and a lower turns counter disposed near a lower longitudinal end of the first tubular.
11. The method of claim 1, wherein the second connection is monitored by calculating a differential between rotation of the quill and rotation of the first tubular.
12. The method of claim 11, wherein the second connection is further monitored by calculating a differential between the torque exerted on the first tubular and a second torque exerted on the quill.
13. The method of claim 1, wherein:
the second connection is between the quill and a torque head or spear gripping the first tubular, and the second connection is monitored by calculating a differential between rotation of the quill and rotation of the torque head or spear.
