Many forms of artificial lift have been designed to deliquify gas wells. Plunger Lift is one form, utilizing the wells natural reservoir pressure as the prime energy source for removing the liquids from the bottom of the well bore. Intermittent operation of a motor valve installed on the tubing, allows fluid to be lifted to the surface, utilizing the free running plunger as an interface between liquids accumulated in the bottom of the well and the stored gas in the annulus. There are many variations of plunger lift employing multiple motor valves and many different sub-surface mechanical tubular arrangements. Chamber Lift is another form of artificial lift extending from Gas Lift. Combinations of Gas Lift and Plunger Lift have been used in the past and the technique described within is an extension of those methods.
