Abstract
A system for measuring drilling and completion operational parameters in a tubular handling system is provided. The system includes a sensor sub connected below a top drive of the tubular handling system; one or more sensors within the sensor sub, for measuring, in the form of electrical signals, operational parameters; one or more low-power integrated circuits within the sensor sub, for receiving electrical signals from the sensors and digitizing the signals; two or more radio frequency (RF) transmitters located in the sensor sub, for transmitting the digitized signals; one or more commercially available lithium batteries within the sensor sub and remote receiver hub located remote from the tubular handling system and including a remote antenna for receiving the digitized signals from the two or more RF transmitters; one or more processing units for processing received digitized signals into engineering units for each of the operational parameters; and an input/output data connection for communicating operational parameters to an operator.
