Abstract
An interventionless system and method: of detecting a downhole activation device are provided. The system includes a first detector disposed downhole in a fluid pathway and; a second detector disposed downhole of the first detector in the fluid pathway. In one exemplary embodiment, the detectors include a pair of ultrasonic transducers that generate signals indicative of fluid pathway flow. Differences in the signals between the detectors are indicative of the presence of the downhole activation device within the fluid pathway. The system also includes a deployment port disposed above the second detector from which the downhole activation device may be deployed into the fluid pathway.
