Abstract: A method of releasing plugging devices into a wellbore can include conveying a dispensing tool to a desired downhole location in the wellbore, the dispensing tool including a container, and then releasing the plugging devices from the container into the wellbore at the downhole location. A plugging device dispensing system for use with a subterranean well can include a dispensing tool having a container configured for containing multiple plugging devices, and an actuator operable to release the plugging devices from the container at a downhole location in the well.

Abstract: A method can include deploying a plugging device into a well, the plugging device including a body, and an outer material enveloping the body and having a greater flexibility than a material of the body, and conveying the plugging device by fluid flow into engagement with the opening, the body preventing the plugging device from extruding through the opening, and the outer material blocking the fluid flow between the body and the opening. In another method, the plugging device can include at least two bodies, and a washer element connected between the bodies, the washer element being generally disk-shaped and comprising a hole, a line extending through the hole and connected to the bodies on respective opposite sides of the washer element, the washer element preventing the plugging device from being conveyed through the opening, and the washer element blocking the fluid flow through the opening.
