ABSTRACT:
The invention relates to the production of hydrocarbons in the form of oil and gas, from a well activated by a pumping system. According to the invention, a hydrocarbon production well comprising a submerged pump (5) driven by an electric motor (6), an oil outlet choke (17) and a gas venting choke (22) is operated by acting, during the various production phases, on the chokes and on the speed of the electric motor (6) either in turn or simultaneously. Furthermore, correct operation of the well is constantly checked and it is also checked that the current drawn by the motor (6) does not cross thresholds that vary as a function of the speed of the motor (6). The invention finds its application in the oil industry.
