Abstract
There is provided a method and apparatus for removing liquid from a well using well bore pressurized gas. A U-shaped tube having a small orifice near the bottom thereof is received in the well. The upper portions of both legs of the tube are connected to well bore pressurized gas. A liquid sensor is received in one leg of the tube. When liquid flowing into the tube through the orifice rises to the level of the sensor, a valve, which is connected to one leg of the tube, is opened and the well head pressurized gas forces the liquid out of the tube and then out of the well.
