Title: Method of controlling a hydrocarbons production well activated by injection of gas

Abstract: The invention relates to a method for controlling a liquid and gaseous hydrocarbons production well (1) activated by injection of gas, the well comprising a production string (2) fitted with an adjustable-aperture outlet choke (9), into which gas, the flow rate of which can be adjusted by means of a control valve (6), is injected, the method being characterized in that it comprises a start-up phase which consists in performing the following sequence of steps: a step of initiating the production of hydrocarbons a step of ramping up to production speed followed by a production phase, during which phases the outlet choke (9) and the control valve (6) are operated in such a way as to maintain the stability of the flow rate of the produced hydrocarbons.
