Abstract
A flow control system includes a nozzle for controlling the flow of fluids into production tubing from a hydrocarbon containing reservoir. The nozzle comprises a passage extending between an inlet and an outlet, wherein the passage comprises converging and diverging sections separated by a corner. The nozzle serves to effectively choke the flow of steam and thereby allows preferential production of hydrocarbons.
