Abstract: Water, with gas entrained therein, collecting in the bottom of the casing of a gas producing well is continuously removed using an ejector in the inner of a pair of coaxial tubes mounted in the casing by continuously pumping drive water downwardly between the two tubes, radially inwardly through apertures in a nozzle body and upwardly through a nozzle at the top of the nozzle body into a suction chamber to draw water from an inlet duct at the bottom end of the inner tube through longitudinally extending passages in the nozzle body; the resulting mixture of drive water, well water and gas being discharged through a multi-stage diffuser and the inner tube to a separator, where the gas and water are separated. The separated gas can be used to operate a gas engine for driving the pump, which feeds drive water to the ejector, and the well water can be re-used as drive water.
