Embodiment Construction

[0014]Referring now to the drawings, and particularly to FIGS. 1-3, a preferred embodiment of the venturi siphon atomization liquid lift apparatus of the present invention is shown and generally designated by the reference numeral 10.

[0015]With reference to FIGS. 1-3, there is shown a diagrammatic partial view of a well casing 100 positioned within a borehole 120 drilled into a formation 125. The venturi siphon atomization liquid lift apparatus (VSALL) 10 is shown positioned within the casing 100 at a bottom hole location 110. It is important to note, the VSALL 10 can also be set within a tubular that is run into a well casing.

[0016]The VSALL 10 operates to increase gas production from the well by lifting accumulated formation fluid using only the transport velocity or energy of the gas being produced. The VSALL 10 depends upon basic laws of physics to lift the formation fluid to the surface.

[0017]In doing so, the VSALL 10 includes a body 12 of dimensions allowing the body to be run...

Abstract

A method and apparatus for increasing the production of a hydrocarbon well by removal of accumulated formation fluid from the bottom of the well. The apparatus includes a body positionable down hole and a sealing assembly, with a converging-diverging nozzle installed axially within a through bore extending through the body at a position below the sealing assembly. A fluid lift passage extends from the accumulated formation fluid through the body and into the throat of the nozzle. The entrance into the throat of the nozzle includes inwardly tapered shoulder portion position below the opening of the fluid lift passage into the throat. The apparatus creates a low-pressure zone within and lifts the accumulated formation fluid into the throat where it is atomized by a high velocity flowing production gas. The atomized fluid is carried to the surface of the well by the production gas where it is then separated from the gas. The method includes the installation of an apparatus within the well.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 743,691, filed Mar. 23, 2005, the entire of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention generally relates to an apparatus and a method for removing formation fluids from the bottom section of hydrocarbon producing wells. More specifically, an apparatus which uses the natural flow of gases to enhance the production of hydrocarbons, such as gas, from a subsurface wellbore.BACKGROUND OF THE INVENTION[0003]It is common for a gas well to produce liquids in addition to gas. These liquids, typically termed as formation fluid, may include water, oil, and condensate. The accumulation of formation fluid in the well can effect the flow characteristics of the well resulting in low production or no production at all.[0004]There exists several methods of removing or recovering the formation fluid from the well to simulate further p...
