Abstract
A method of deploying plugging devices into a subterranean well can include conveying a bottom hole assembly into the well, the bottom hole assembly including a plug deployment tool, and actuating the plug deployment tool, thereby gradually dispensing the plugging devices from an interior of the plug deployment tool into the well. The plugging devices may be dispensed from the plug deployment tool all at once, or in discrete intervals.
Claims11
A plug deployment tool for use in a subterranean well, the plug deployment tool comprising:
- a first piston positioned in an outer housing;
- multiple plugging devices disposed in the outer housing;
- and
- a fluid pump configured to pump fluid into the outer housing and thereby displace the first piston to dispense the plugging devices from the outer housing.
A plug deployment tool for use in a subterranean well, the plug deployment tool comprising:
- an atmospheric chamber;
- an openable closure that isolates the atmospheric chamber from a fluid volume;
- multiple plugging devices contained in an outer housing;
- and
- a piston configured to displace the plugging devices out of the outer housing in response to the closure being opened.
