Abstract
A technique includes running a plug assembly inside a tubing string of a well; deploying an untethered object in the tubing string; and communicating the untethered object into a passageway of the plug assembly to land the untethered object in a seat of the plug assembly. The passageway has a maximum cross-sectional dimension that is larger than a maximum cross-sectional dimension of the untethered object. The technique includes using the landed untethered object to form a fluid barrier in the tubing string.
