Abstract
A method of dispensing a plug can include deploying the plug into a tubular string including a plug dispenser tool, and applying a pressure differential across the plug, thereby discharging the plug into an annulus surrounding the plug dispenser tool. A plug dispenser tool can include an outer housing having a plug discharge port that provides fluid communication between an exterior of the outer housing and a flow passage extending longitudinally through the plug dispenser tool, and a piston slidably disposed in the outer housing between a closed position in which the piston blocks fluid flow through the plug discharge port, and an open position in which fluid flow through the plug discharge port is permitted. A system can include a plug dispenser tool configured to discharge the plug into an annulus surrounding the plug dispenser tool in response to a predetermined pressure differential applied across the plug.
