  • Patent number: 7147058
    Abstract: For production of hydrocarbons with high and medium gas-oil ratio from a well with a wellhead and a bottomhole communicating with a formation, and with a casing and a tubing located inside the casing and forming a space therebetween, steps are performed and means are provided for establishing a flow of hydrocarbon-containing fluid inside the tubing from the bottomhole to the wellhead, introducing gas into the space between the casing and the tubing so that the gas passes into the tubing and enhances the flow of the hydrocarbon-containing fluid from the bottomhole to the wellhead with simultaneous reduction of pressure in the bottomhole resulting in an increase of a pressure differential between the formation and the bottomhole; and introducing in the bottomhole a device which increases the pressure in the bottomhole so that the pressure differential between the formation and the bottomhole decreases and therefore a gas blockage in a near bottomhole zone of the formation is reduced to maintain an oil flow from
