Abstract
Systems and methods for a flow activated choke device that is activated by the choke device directly interacting with the flow of fluid in an upstream direction. More specifically, a choke device formed of chain like materials that is configured to be extended in a first mode and compacted in a second mode, wherein the choke device moves from the first mode to the second mode responsive to an upward fluid flow rate being greater than a flow rate threshold.
