Abstract

Provided is a fluid flow control system, a well system, and a method. The fluid flow control system, in one aspect, includes a flow restrictor operable to receive production fluid having a pressure (P3) and discharge control fluid having a control pressure (P2), and a fluidic diode placed between the flow restrictor and the tubing, the fluidic diode configured to increase the control pressure (P2) to a higher control pressure (P2⁺⁺) when the fluidic diode encounters lower viscosity fluids and is configured to increase the control pressure (P2) to a lower control pressure (P2⁺) when the fluidic diode encounters higher viscosity fluids. The fluid flow control system, in one aspect, further includes an inflow control device having a production fluid inlet, a control inlet operable to receive control fluid having the higher control pressure (P2⁺⁺) or the lower control pressure (P2⁺), and a production fluid outlet.
