Abstract
An autonomous inflow control system includes an inlet conduit connecting production fluid to an input of a first flow modifier including one of a laminar flow device and a turbulent flow device. An intermediate conduit is connected to a first fluid output of the first flow modifier, and connects the first flow modifier to a second flow modifier configured to provide a second fluid output, the second flow modifier including another of the laminar flow device and the turbulent flow device. The system includes a signal path configured to provide a first signal and a second signal, and a valve responsive to a difference between the first signal and the second signal. The first signal corresponds to the first fluid output and the second signal corresponds to the second fluid output, or the first signal corresponds to the input and the second signal corresponds to the first fluid output.
