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.
Claims20
An interventionless system for detecting a downhole activation device launched downhole, comprising:
- a first detector generating a first signal;
- a second detector generating a second signal, the second detector located downhole from the first detector;
- wherein the presence of the downhole activation device is detected when the second signal differs from the first signal.
A method of detecting a downhole activation device, comprising:
- launching the downhole activation device through a pathway;
- generating a first signal using a first detector;
- generating a second signal using a second detector located downhole from the first detector;
- comparing the signals from the first and second detectors;
- detecting the presence of the activation device downhole where the first and second signals are different from each other.
