Abstract
A method of deploying plugging devices can include conveying a bottom hole assembly into a well, the bottom hole assembly comprising a plug deployment tool, and actuating the plug deployment tool, thereby dispensing at least one of the plugging devices from an interior of the plug deployment tool. A plug deployment tool can include a first chamber, a valve that isolates the first chamber from a second chamber, multiple plugging devices contained in an outer housing, and a piston that displaces one or more of the plugging devices out of the outer housing in response to the valve being opened. The second chamber can be disposed in the piston and can displace with the piston in response to the valve being opened.

A method of deploying plugging devices into a subterranean well, the method comprising:
- conveying a bottom hole assembly into the well, the bottom hole assembly comprising a plug deployment tool;
- and
- actuating the plug deployment tool, thereby dispensing at least one of the plugging devices from an interior of the plug deployment tool into the well.
A plug deployment tool for use with a subterranean well, the plug deployment tool comprising:
- a first chamber;
- a valve that isolates the first chamber from a second chamber;
- multiple plugging devices contained in an outer housing;
- and
- a piston configured to displace at least one of the plugging devices out of the outer housing in response to the valve being opened, the second chamber being disposed in the piston.
