Abstract
Apparatus and method of sensing tension downhole, such as a tension sensing tool for coupling between opposing first and second portions of a tool string conveyable within a wellbore. The tension sensing tool may include a tension-bearing member, a load cell connected along the tension-bearing member and operable to generate information indicative of tension applied to the tension sensing tool, and electronic equipment communicatively connected with the load cell. The electronic equipment may be operable to record the information generated by the load cell and/or transmit the information generated by the load cell to a wellsite surface from which the wellbore extends.
