  • Flow rings for regulating flow in autonomous inflow control device assemblies
    Patent number: 9765602
    Abstract: Disclosed are wellbore flow control devices that allow on-site field adjustments to flow characteristics. One autonomous inflow control device (AICD) assembly includes a base pipe defining one or more flow ports and an interior, a first end ring and a second end ring each arranged about the base pipe, the second end ring being axially-offset from the first end ring such that a fluid compartment is defined therebetween, an AICD arranged within the fluid compartment and having at least one fluid inlet and an outlet configured to be in fluid communication with one of the one or more flow ports, and a flow ring arranged about the base pipe and in fluid communication with the AICD, the flow ring being operable to regulate a fluid flow into the interior of the base pipe and being accessible and manipulatable by a well operator on-site.
