Abstract:
A system and method for creating a controlled geyser well with sustained periodical production includes a cap (16) which prevents gas from entering a well tubing (14) while allowing liquid to enter and accumulate in the tubing, means for compressing the gas, and means for injecting the gas in the annulus so that the gas enters the bottom end of the well tubing (14), thereby creating a controlled geyser effect which blows out most of the liquid residing in the well tubing (14). The gas being compressed can be a produced gas or a supplied gas.
