The method according to claim 21, further including the step of controlling the cycling of pumping units removing said column of liquid in said well based on comparing the determined liquid level against a predefined liquid level. 27. The method according to claim 21, further including the step of controlling a plunger lift system in said well for removing said column of liquid based on comparing the determined liquid level against a predefined liquid level. 28. The method according to claim 21, wherein said step of introducing a gas to the bottom of said column of liquid is through a piggy back line running from the surface to said bottom of said column of liquid so as to permit said gas to bubble up through said column of liquid when the pressure of said gas overcomes the pressure at said bottom of said column of liquid. 29. A system for determining a liquid level of a column of liquid contained in a well for controlling an artificial lift system for said well based on said liquid level of said column of liquid, comprising: a gas line for introducing a gas adjacent to a bottom of said column of liquid in small amounts which are sufficient to overcome the pressure exerted at the bottom of said column of liquid, or introducing said gas in small amou
