ABSTRACT:
A gas extraction device for down hole oilfield applications utilizes the flow of the liquid, created by an artificial lift device, to produce conditions by which the gas is drawn into tubing. A venturi creates a low pressure area through a constricted section of the tubing. The pressure within the throat of the venturi drops the pressure in the casing. The device is axially adjusted to allow communication ports to a lower pressure area of the casing annulus. The lower pressure in the venturi draws the gas into the liquid stream and into the production tubing above the device. The gas is then transferred through the well head within the liquid stream.
