Abstract
A plugging device, apparatus, and method. The plugging device includes an expandable member configured to move from a first, retracted position to a second, expanded position, a counter configured to count a number of restrictions in a conduit that the plugging device passes through, and an actuator configured to move the expandable member from the first position to the second position in response to the counter counting a predetermined number of restrictions. The expandable member in the expanded position prevents the plugging device from passing through a target restriction.
