Abstract
A device is taught for measuring and wirelessly transmitting one or more parameters during wellbore operations. The device comprises a torque sub releasably connected to a top drive at a first end and having a second end such that the torque sub rotates with the rotating top drive, one or more sensors for measuring rotational, torque and torsion parameters, a wireless power source and a signal transmitter connected to the one or more sensors for wireless transmission of data collected by the one or more sensors to a computer. Systems and methods are also provided for connecting threaded tubulars for use in a wellbore.
