  • Method and device for production of hydrocarbons
    Patent number: 6173784
    Abstract: Hydrocarbons are produced from a well having a bottomhole and a wellhead and communicating with a formation, by producing a flow of hydrocarbon-containing formation fluid from the formation at the bottomhole of the well, transforming the flow of the formation fluid from the formation at the location of transformation into a finely-dispersed gas-liquid flow with a liberated gas forming a part of the gas-liquid flow, so that a column of the formation fluid is formed in the well from the depth of the formation to the location of transformation, and a column of the finely-dispersed gas-liquid flow with a liberated gas is formed in the well between the location of the transformation and the wellhead, and automatically maintaining a pressure of the formation fluid at the bottomhole in the well higher than saturation pressure, substantially independently from changes in properties of formation and formation fluid.
