The disclosure relates to a method for extracting hydrocarbons from a tank including providing a facility having an injection well including at least one tube for steam injection, a production well including at least one hydrocarbon extraction tube, a set of measuring sensors, at least one hydrocarbon extracting pump in the production well, an automaton for controlling and monitoring the running of the facility; rejecting the steam into the injection well; extracting the hydrocarbons with the pump of the production well; and controlling speed of the pump depending on the difference between the measured temperature at the pump input and the evaporation temperature calculated on the basis of the measured pressure at the input of the pump. The method enables an increase in hydrocarbon production.

Method for extracting hydrocarbons from a tank and hydrocarbon extraction facility

Some embodiments include a heavy-oil-based hydrocarbons effluent production installation for the production of hydrocarbons from at least one well. The installation includes an effluent-lightening fluid injection system at the bottom of the well, an effluent-evacuation pump, a plurality of sensors that measure physical units relating to the installation, and an automated device suitable for optimizing the lightening-fluid injection flow-rate and for regulating the pump speed. The automated device regulates the pump speed according to the physical units and a predetermined target production value. The speed of the pump and the physical units are within a predetermined range of values. some embodiments include a hydrocarbons production method in such an installation. Some embodiments make it possible to ensure a minimum consumption of lightening fluid, while ensuring good operation of the pump and good productivity of the well.

Hydrocarbons production installation and method

A method is proposed for heating a hydrocarbons reservoir, comprising The method makes it possible to more precisely control injection of the steam into the wellbore, throughout the circulation phase, optimizing the steam injection flow rate throughout the circulation phase while still ensuring the safe operation of the steam circulation phase.
