Abstract (en)
A system for controlling production from a gas-lifted oil well comprises a dynamically controlled choke (1) for adjusting the flow of crude oil from a production tubing (2) of the well. The system is capable of maximizing and stabilizing the crude oil production in an accurate manner and without requiring downhole equipment. <IMAGE>
