Abstract
A technique includes deploying an untethered object though a passageway of a string in a well; and sensing a property of an environment of the string, an electromagnetic coupling or a pressure as the object is being communicated through the passageway. The technique includes selectively autonomously operating the untethered object in response to the sensing.
