Abstract
A method of deploying plugging devices can include actuating a plug deployment tool, thereby dispensing at least one plugging device into a well, the actuating including flowing fluid from a first chamber to a second chamber of the plug deployment tool. A plug deployment tool can include a first chamber isolated from a second chamber, and a piston to displace at least one plugging device out of an outer housing in response to fluid communication between the first and second chambers. A plug deployment system can include a valve that isolates the first chamber from the second chamber, a first piston biased by a spring to pressurize the first chamber, and a second piston to displace at least one plugging device out of the outer housing in response to the valve being opened.
Claims26
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,
- in which the actuating comprises flowing fluid from a first chamber to a second chamber of the plug deployment tool.
A plug deployment tool for use with a subterranean well, the plug deployment tool comprising:
- a first chamber;
- a second chamber isolated from the first chamber;
- multiple plugging devices contained in an outer housing assembly;
- and
- a piston configured to displace at least one of the plugging devices out of the outer housing assembly in response to fluid communication between the first and second chambers.
A plug deployment system for use with a subterranean well, the plug deployment system comprising:
- a first chamber;
- a valve that isolates the first chamber from a second chamber;
- multiple plugging devices contained in an outer housing assembly;
- a first piston that is biased by a spring toward the first chamber to pressurize the first chamber;
- and
- a second piston configured to displace at least one of the plugging devices out of the outer housing assembly in response to the valve being opened.
