    摘要: The present invention concerns a system for extracting the liquids from a well producing liquid and gas, in which the system comprises: a separation wall (105) defining, in the well, a first space (113) and a second space (112); a liquid-gas separator (117); and a system (108) for eliminating separated liquid. Moreover, the first space is suitable for conveying a mixture comprising the gas and liquid from a production area to the separator. Furthermore, the separator is suitable for separating the gas and liquid from the mixture. Moreover, the second space is suitable for receiving the liquid separated from the mixture. Finally, the elimination system is suitable for eliminating the separated liquid using at least the gravitational potential energy of said separated liquid in the second space.

    摘要: There is provided a system for producing oil from a well bore extending through a fossil fuel reservoir. The system includes a plurality of perforations defined in the casing proximate the fossil fuel reservoir. A gas flow tube is in communication with the annulus volume of the casing proximate the wellhead. A gas valve is coupled to the gas flow tube, with the gas valve configured to selectively open and close the gas flow tube. A controller, is coupled to the gas valve, with the controller configured to control the opening and closing of the gas valve. The opening and closing of the gas valve maximizes the volumetric rate of oil flow into the annulus volume through the perforations from the reservoir by displacing liquid in the annulus volume with a gas volume between the gas valve and the perforations.
