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, at least one AICD arranged on the base pipe and having at least one fluid inlet and an outlet in fluid communication with one of the one or more flow ports, and a fluid barrier configured to be arranged about the at least one AICD by a well operator on-site and configured to isolate the at least one AICD from an influx of fluid during operation.
