Abstract

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 choke (1) is controlled by a control module (CM) comprising a PID controller (PID) which is set to dynamically control the opening of the choke (1) such that the pressure (CHP) in the lift gas injection conduit is minimized and stabilized. The system is capable of maximizing and stabilizing the crude oil production in an accurate manner and without requiring downhole equipment.
